Last weekend Jakob Herrmann, Austrian ski mountaineer and Suunto ambassador broke the 24-hour skimo world record. He ascended 24.242 meters (79.534ft) in 24 hours in Radstadt, Austria. To put that into perspective, Jakob’s average hourly ascent was over 1.000 meters, and the total ascent was more than equal to six laps up to Mont Blanc, the tallest mountain in the Alps, from the valley floor in Chamonix. The previous 24-hour world record was 23.486 meters set by Kilian Jornet. Jakob not only broke the record but was also the first person ever to climb over the 24.000-meter mark. Jakob skied all together 34 laps up and down a ski slope that has 713 meters of ascent. A single lap was 2,55 km and in total he skied more than 170 kilometers. During one of his descents, he hit a max speed of 108 km/h! We caught up with Jakob shortly after his record-breaking ski. Read on to learn more! Suunto: When did you set the 24-hour record as your target? Jakob: I just love to spend time on my skis for hours! It has always been a dream for me to go on touring skis for 24 hours to see how many meters in altitude I can manage. I just want to know what limits I can reach and how far beyond them I can go. Did you do some specific training for it? In November and December, I did a lot of long and easy sessions on my skis followed by short and hard interval sessions to get the speed and strength. In the last two weeks before my 24h I only did short, easy sessions and some short, but hard ones and one race to get used to the suffering! Have you tried a personal 24h challenge before? No, but I did one session with 10.000m of ascent in 9h30m in the middle of December. I felt super strong although I did it self-supported. I think with more long sessions my head and muscles would have gotten tired and the pace would have gone down. So, I did more split sessions with 5.000m+ in the morning and a second session in the evening. How did you pace yourself? For 90% I listened to my feelings. When I felt strong, I went faster and when I felt tired, I went a bit slower! My supporters always gave me the lap times. In addition, I observed the vertical speed per hour on my Suunto Race. How did your pace change through the 24 hours? I did the first loops very fast – my first uphill was in 30’. The first 10 loops were all between 30-36’. After that, I was between 37-40’. My slowest uphill was 42’ on the 24th loop when I had my lowest point. The hardest part for me was the early morning when I felt the freezing cold temperatures of around -8 degrees, especially during the downhills. In the end, I was able to push again, and the last 7 loops were all between 38-40’. The average was 38’20”. So, I think the secret to my success was that I was able to keep the pace constant. Did you have some surprises on the way? I didn’t have any negative surprises – only positive ones! I was surprised that so many friends joined me on my way and so many people followed me on-site or in the live stream. Did you have anyone keeping you company? Yes! I was only 7 hours in total alone: 4 hours during the night and 3 hours during the day. I am super happy I had so many friends on my side, but I enjoyed also the loops when I was alone! When did you realize that you would make it? From the beginning… No joke! I had a strong day, and after some laps, I knew, that I could do it. After 18h I was 100% sure that I would make a new record, but I wasn’t sure if it would be more than 24.000m. After 21h I was sure I’d do the extra lap to climb more than 24.000 meters. Which Suunto did you use? I had the Suunto Race – and it worked perfectly. The battery lasted unbelievably well; I had more than 40% of the battery left in the end even though I had the GPS on the best settings, the light was always on and I used the SuuntoPlus Loop sport app. What was your nutrition strategy? 100 grams of carbs per hour. I always had 300ml of Maurten Drink Mix320 with me. Every loop I had a Maurten gel and every 4th loop I ate a Moonvalley bar and no gel. After the 8th and 16th loops, I had warm salted potatoes and a warm soup on the top. For the last 6 loops, I stopped with Maurten Drink Mix320 and Moonvalley bars and changed to Red Bull, water, and Pringles! Did you have a big crew supporting you? I had two supporters in the valley and two on the top. Philipp [Reiter] was everywhere taking pictures and pushing me! Also, my parents were nearly 24 hours on my side to give me a good feeling! How do you feel now, one day after the enormous effort? I feel super good. My energy and legs are strong – only my feet are swollen, and I have some blisters. I am surprised… but I think my nutrition strategy was really good. I never felt completely out of energy.

Rise&Fall Mountain Attack Rise & Fall Mayrhofen Four people, one team, no mercy - on January 14th, everything will be demanded of the athletes. Each team consists of a ski mountaineer and mountain biker who will give their best in the uphill. A paraglider and skier cover the downhill and do complete the team and risk everything to be the first crossing the finish line. Among the more than 300 participants this year are Johanna Hiemer on touring skis, Aaron Durogatti and Judith Rubner on paragliders and Marius Quast on skis. The special thing about it is that both Johanna Hiemer and Judith Rubner will be competing in a women's team. "I'm looking forward to this unique event - 4 different sports combined in on event is unique. The atmosphere is amazing." - Johanna Hiemer We asked Chris Ebenbichler, the organizer of the event, a few questions in advance: What is important for the teams? The teams must form a homogeneous unit. The handover in the individual disciplines is crucial and, of course, the spirit within the team is always better when the athletes know each other. It's great to see how the team members cheer each other on, motivate and support each other. At the end of the day, they win or lose together and create unforgettable moments and emotions. What is the most challenging discipline? It's difficult to define. It's a high-intensity event and the short duration of the individual disciplines means that the athletes are constantly pushing themselves to the limit and in the red zone. There is no time to catch your breath and you have to stay focussed. It's a sprint for touring and biking, the paragliders are challenged by the running course and the difficult start section and for the skiers, with a 3-minute giant slalom and the obstacles before the finish, the lactate level is almost unbearable What is the discipline in which you can win everything and lose everything? The two RISE disciplines of ski touring and mountain biking certainly offer the most time. Unfortunately, you can lose everything if you fall in the last discipline, skiing. How do the teams prepare for this special event? The teams and athletes prepare very individually. For some amateur athletes, having fun comes first. The professionals, on the other hand, take things very seriously. For the ski tourers, it's a kind of benchmark for the start of their season and the mountain bikers see it as the starting signal for preparation and the first training courses in warmer climes. However, the same applies to everyone: Without adequate preparation, it will be a knife-edge ride. How many teams are competing? Men & women? There will be 80 teams and 10 individual starters on the day of the event. We hope to welcome around 20 women's teams to Mayrhofen this year. ©Michael Werlberger  SATURDAY, 13.01.2024 Europahaus Mayrhofen From 16.00 to 18.30: Bib-Collection & Pastaparty19.00: Welcoming and briefing 20.00: "RED BULL X-Alps 2023": Multimediashow with Christian "CHRIGEL" Maurer in the Europahaus - Ticketinfo SUNDAY, 14.01.2024 Eventarea in front of Ahornbahn 11.00: Entrance - Warm up11.30: START - RISE&FALL KIDS-RACE 2024+ Prize ceremony: KIDS-RACE12.45: START - RISE&FALL SINGLE-RACE 202413.00: START - RISE&FALL TEAM-RACE 2024directly afterwards: Flower CeremonyFrom 16.00: Live music with the band "Jukebox Brothers"16.00: Prize ceremonyApprox. 17.00: RISE&FALL Afterparties in Mayrhofen   Mountain Attack The 26th Mountain Attack will take place on 19th of January 2024 and athletes will give their best over 6 distances. In Saalbach-Hinterglemm, hundreds of athletes will once again give their all this year - the 3-person relay over the marathon distance is new. Suunto athlete Jakob Herrmann is not only last year's winner and therefore Mountain Man 2023 with a time of 2:22:14 but will also be on the starting line again this year. "The challenge is definitely the first mountain! You tend to go too fast or lose a lot of energy because it's so steep. In 2020, I was almost 1,5 minutes behind the leaders on the first climb and I finished 2' ahead with a new course record," says Jakob Herrmann. It remains to be seen whether a course record will be set this year in addition to his preparation for the 24h project, but we will certainly be there. © Philipp Reiter   Roland Kurz and his team have been organizing the Mountain Attack for 26 years now and give us a closer look at the ski touring event of the year: How did the Mountain Attack come about? We started the first race in 1999. It was very well received internationally, the media reported on it and so the idea became a vision - the Mountain Attack. It has since become a touring ski cult event, the biggest and toughest night-time piste ski touring race in the world with participants from over 20 nations and numerous side events, a meeting point for the scene, business and sport. What makes the Mountain Attack so special? The Mountain Attack is a race over several distances (Schattberg Race - vertical, Tour and Marathon - individual) where it is possible for amateur and hobby athletes to compete with the best athletes in the world in a race at the same time, in the same weather conditions and with the same snow conditions. Thousands of spectators on the various peaks and in the valley are up close to the racing action and motivate all participants to achieve their personal best. A unique atmosphere for all enthusiastic ski mountaineers and fans. And: because the course has been the same for 25 years, everyone can compare their own performance with that of previous years. What is the biggest challenge and who is the Mountain Attack for? The route. The start on foot, running through the centre of Saalbach, with thousands of spectators, and especially the first steep climb up the Schattberg with over 1000 metres of altitude difference is a special challenge - affectionately called "Il Muro" (the wall) by the Italians. The steep climbs and the long and steep descents throughout the race are unique and very challenging. Everyone is welcome, even without a national or international athlete's licence, who loves the sport and is an experienced ski tourer. Numerous athletes from summer sports, such as triathletes, trail runners and cyclists, like to use ski mountaineering in winter as optimal training preparation and are represented in large numbers at the start of the Mountain Attack. © Philipp Reiter PROGRAM FOR FANS AND SPECTATORS FRIDAY, 19.01.2024 13:00: Start Junior-Sprint: Schattberg-Basisareal.

Race to the Summit Two years ago, Dani Arnold completed the biggest project of his life: climbing the six large Alpine north faces – alone and in record time. The project occupied, accompanied and shaped him over a period of 10 years. Now the Netflix is devoting a 90-minute report to three of these climbs. Race to the Summit features the dizzying feats of Dani Arnold and the late Ueli Steck, two great Swiss alpinists and long-time Suunto ambassadors. Experienced mountaineers need a day or more to climb the infamous north faces of the Eiger or Matterhorn. But Dani and Ueli climbed them alone in less than three hours. The duel thrilled the climbing world and electrified the media. Watch the trailer above and the full film on Netflix.   Lost Then Found TDS winning athlete Christian Meier shares his inspiring story in Lost Then Found. Christian started his athletic career as a cyclist and has since made a transition from the pro peloton to the top of ultra-running. ”Life is a constant evolution of who you are as a person and Lost Then Found marks an important turning point in my life not only as an athlete but as an individual. From losing cycling to finding trail running this is a story of self-discovery and I am happy to be able to share that journey,” says Christian.   Arctic Lines – Sunny Car Center In the Arctic Lines video series, backcountry snowboarder Antti Autti explores the vast wilderness of northern Finland, Sweden, and Norway. The series is now in its third season, and in the latest episode, 'Sunny Car Center,' Antti seeks—and finds—a new special zone in Northern Norway. ”Exploring expands your horizons and finding new locations is one of the most important aspects of freeriding,” says Antti.   Balkan Express Ski mountaineers Jochen Mesle and Max Kroneck rode 2500 km from Greece to Germany – and stopped to ski along the way. Balkan Express, their film about the adventure, has won acclaim at international film festivals. “We really wanted to experience some mountains, cultures, people we didn't know. We looked at a map of Europe and saw that the Balkans are pretty interesting. The sport side wasn’t the main focus of the project. It was about getting to know the culture and people,” says Max.   Nomadland – Bikepacking in Mongolia Alba Xandri and Erreka Calmet found beautiful landscapes, friendly people and an epic adventure while bikepacking in in the Mongolian grasslands – and made a film about it. ”Mongolia far exceeded our expectations. It is a backcountry bikepacker’s paradise,” says Alba.   Ride to Ski – Bikepacking adventure through the Dolomites Lack of snow forced Henna Palosaari to think outside the box and led her to invite two of her friends, Sami Sauri and Malva Björkman, on a bike & ski adventure. The 9-day journey that combined two of her favorite sports, turned out to be a beautiful mix of sweat, laughs, ice, snow, and friendship.  ”It wasn’t a pure sufferfest,” Henna laughs.   Max Ammer, Raja Ampat and the richest reefs in the world This is an oldie but goldie: Max Ammer, founder of Papua Diving and two Eco Resorts, Sorido Bay and Kri Eco Resort, shows us why these incredible projects are more than just places to stay, dive and enjoy the unique ecosystems. Over the past 30 years, a remarkable conservation project has unfolded. The local team, with unwavering dedication, has prioritized the protection of the flourishing ecosystem. This strategic focus has proven to be wise, as the tangible outcomes of their hard work, long-term planning, and precise execution are evident in the thriving fish and coral counts. This stands as a rare case where the reefs are experiencing unprecedented richness – and gives hope for other areas as well.   Lead image by Richard Bucher / Ride to Ski

Keep an eye on what's happening inside your muscles with a Train.red muscle oxygen sensor and your Suunto watch. Exercise technology is developing fast and new ways to measure and understand what is going on in our bodies emerge frequently. SuuntoPlus gives sensor companies an agile way to integrate with Suunto watches for real-time monitoring and data collection. The latest addition to compatible devices is Train.Red muscle oxygen sensor. Muscle oxygen sensors are tiny devices that monitor the level of oxygen saturation in the muscles. The concentration of oxygenated and deoxygenated hemoglobin in muscle tissue is commonly measured using near-infrared spectroscopy (NIRS) devices. These sensors provide valuable data by detecting the saturation of oxygen in the muscle, which can assist athletes in maximizing their performance and recovery. How Muscle Oxygen Sensors Work Muscle oxygen sensors work by emitting light into the muscle tissue and measuring the amount of light that is absorbed and scattered by the hemoglobin in the muscle. This allows the sensor to determine the concentration of oxygenated and deoxygenated hemoglobin in the muscle tissue, which can be used to calculate the oxygen saturation level.   When using SuuntoPlus Train.red sport app your TrainRed muscle oxygen sensor will provide real-time feedback on the oxygenation status of muscles.   The Advantages of Muscle Oxygen Sensors in sports Performance Evaluation One of the key advantages of sports muscle oxygen sensors is that they provide vital data on an athlete's performance. Athletes can receive insight into how their bodies are doing and how they can enhance their performance by monitoring the saturation of oxygen in the muscles during exercise. Improving Endurance Muscle oxygen sensors can also be used to improve endurance. By monitoring the oxygen saturation levels in the muscles during exercise, athletes can determine when their muscles are becoming fatigued and adjust their training accordingly. This can help athletes train more efficiently and effectively, leading to greater gains in endurance and overall performance. Avoiding Injury Muscle oxygen sensors can potentially be utilized to aid in injury prevention. Athletes can tell whether their muscles are exhausted and at risk of injury by monitoring the oxygen saturation levels in their muscles. This enables them to modify their training to avoid injury and retain optimal performance. Personalized Training Muscle oxygen sensors can also be used to create personalized training plans. By analyzing the data provided by the sensors, athletes and coaches can identify areas of weakness and develop training plans that are tailored to their specific needs. This can lead to more efficient training and greater gains in performance. Monitoring the Recovery Process Finally, muscle oxygen sensors can be employed to track recovery progress. Athletes can evaluate how quickly their muscles recover by measuring the oxygen saturation levels in their muscles after exercise and adjusting their training accordingly. This can aid in the prevention of overtraining and injury, resulting in more consistent performance over time. How to use Train.red with Suunto When using SuuntoPlus Train.red sport app your TrainRed muscle oxygen (SmO2%) sensor will provide real-time feedback on the oxygenation status of muscles, helping you optimize your training and performance. Go to Suunto app’s App Store and save Train.red sport app in your sport apps. Go to “My SuuntoPlus sport apps” and “install” the Train.red sport app. Sync your watch with the app Before starting an activity, go down to the exercise settings and select Train.red sport app. During activity your Train.red data will be shown on a specific Train.red screen. After the activity your muscle oxygen data is saved and synced to Suunto app for post-exercise analysis.

It was late February in Innsbruck. Henna sat at her desk, browsing the map to see what destinations were close by, destinations with great skiing opportunities that could be easily reached by bike. The winter in the Austrian Alps had been the worst in living memory. The usual endless fresh snow had been replaced by grass and mud. Normally, at this time of the year, we were too busy to enjoy the powder days in the snowy resorts to even think about wasting this precious time riding bikes that could do plenty over the summer months. This year was different; it was time to slow things down and finally see if combining two sports, bikepacking and snowboarding, could actually be truly enjoyable. Malva, Sami and Henna. "We're actually doing it!" Malva exclaimed as we hopped on our bikes in Innsbruck. "My bike shakes like crazy, is this normal?" Henna asked, seemingly nervous after the first 500 meters. Sami reassured her that she'll get used to it by the time we reached the Dolomites. Dolomites, a destination with iconic sharp-toothed, sheer-sided mountains that stand enormously tall as the background whether it’s summer or winter. And most importantly, only a couple of hundred kilometers away, making it reachable by bike. The only question was whether our plan of a 5-day cycling and 4-day skiing journey from Innsbruck to Lago di Garda actually was realistic without being only a sufferfest? Snowflakes and sharks “It’s definitely a first, biking up to go ski touring,” Henna gasped as we made our way up to our first skiing spot. This winter, the snow line had been even higher than normal, at around 1000 to 1500 meters. Normally, we would drive up to the snow line and start touring, but not this time. Now, it meant first climbing 600 meters from the village with bikes before changing into skis and tackling the rest of the 750 meters with skis and splitboards. Our bikes were loaded with skis/splitboards, ski/snowboard boots, backpacks, poles, skins, ski clothes, crampons, and sleeping bags, all secured with many, many straps. “At least the body is already warmed up by the time we start touring,” Malva smirked. As we arrived at our accommodation the previous night, the snow had started to fall, giving hope for some fresh lines the next day. The trees and roofs were covered by a thin layer of snow, making the whole town glisten in the morning sun as we hopped on our bikes the next morning, excited for the first ski day. “Watch out for sharks,” Henna shouted as all three of us cruised down a fresh line from Vennspitze. That was the reality; there was still not enough snow to cover all the rocks, but it didn’t stop us from enjoying the first turns of the trip. “Shitty snow but so much fun to be riding!” Malva summed it up as we were riding the last meters down. With smiles or without smiles, the reality was that we still needed to bike another 31 kilometers to our next accommodation. Exhausted, we crossed the border to Italy in the dark, dressed up in all the layers we had, and descended down towards Vipiteno. “I don’t think we can keep on doing this for 7 more days in a row,” Sami said, and we all nodded in silence. Lesson learned - while enjoying a hearty dinner, we decided to split the rest of the days between the two disciplines to make it a smoother and, most importantly, more enjoyable experience. Ice and Dolomiti peaks "No way, is that a ski slope?" Sami shouted after we had just managed to get through a closed trail with hundreds of fallen trees. Route planning on a winter bikepacking trip was a lot different from a normal bikepacking trip. The nice small gravel roads that were usually preferred might be covered by snow or turned into a nordic ski track that had melted into a shiny ice field. Both of these we had to learn the hard way on our trip. “No braking,” Henna screamed as she balanced on the ice field that previously served as a nordic ski track. We survived but decided to reroute the rest of our route to the bigger roads to avoid more such surprises. We pushed our bikes across the ski slope while gazing at the first Dolomiti peak on the horizon. The 90-kilometer journey to Camping Sass Dlacia was a full day mission, but the sheer-sided mountain peaks colored in shades of pink and purple created a warm and unforgettable welcome into the Dolomites. The drumming of the raindrops the next morning not so much. The campsite was located at 1500 meters, but still, it was not enough to turn the rain into snow. “That is usually rideable,” Henna said, pointing out to a peak on our left side as we toured towards Lavarella hut. The lack of snow made it necessary for us to adjust the next day’s plan. There was simply not enough snow to ski the run we had planned to. “The rest of the face is pure ice from here to the top,” Malva said. The snow that had started falling after our arrival at the hut had come with too much wind to stick on the icy slopes. Creativity had been the key this winter, finding a way to make the most out of the current conditions no matter how bad they were. After looking around, we found an interesting-looking small couloir and a snowy-looking bowl that we decided to ski. “Go girls,” Sami wrote on the snow as Malva and Henna hiked up to the couloir. The wind was chilly, but the sun was shining as we rode down. "Not perfect but way better than I expected," Henna said, content for the day. The setting sun colored the sharp-toothed mountains in warm tones, giving the final confirmation for a great day in the mountains. Cheating to maximize the down time “I’m not feeling that good,” Malva said as the highest massif of Dolomites, standing over 3000 meters above sea level, looked down at us. The climb was famous among road cyclists, now tackled by three girls with 40-kilogram bikes loaded with ski gear. “2 kilometers in an hour,” Sami laughed out loud as she looked down at her watch and saw the pace we were moving. “But look at that,” Henna pointed out in awe towards Marmolada as she saw the majestic peaks glowing in the evening light, covered in fresh snow. At that moment, everything made sense, even doing a 9-day ski trip by bike. After seeing the fresh snow on the Dolomiti queen and knowing it was all accessible from the resort’s cable car, we decided to reward ourselves and maximize the time spent skiing down instead of spending it touring up. It was our last day of skiing on this trip after all. “This is why we do it,” Henna screamed out of joy. We found fresh lines between the cliffs, fun turns beside the already tracked ones, good snow and bad snow as we enjoyed the beaming sun and took in the magnificent views overlooking the Dolomites. Smiles bigger than any of the day, we packed the skis on the bike and started a short descent to the next accommodation, only to notice we had booked the wrong one from a village on the other side of Marmolada. Even that, could not ruin our mood that day, we kept riding to the next village and booked a new one from there. The last majestic peaks of Dolomites on our sides and the warmth of the sun growing more intense as we headed towards our last destination, Lago di Garda. Soon the only evidence of the snow and winter was the melting nordic ski tracks. As we passed by the Italian Vineyards, we felt light and relaxed, shed some layers, and chatted with the local cyclists as they passed by us. We knew that we were getting closer to our end destination. Whether it was the tailwind or knowing we could soon pop the champagne bottle gifted to us by our last accommodation, the last kilometers to Riva del Garda flowed in ease. “We actually did it,” Sami shouted as she popped the champagne bottles and sprayed it on Henna and Malva. “And it wasn’t a pure sufferfest,” Henna said, the taste of champagne in her mouth. A 9-day journey combining two of our favorite sports turned out to be a beautiful mix of sweat, laughs, ice, snow, and friendship.

Recovery is a crucial component of training that allows the body to repair and adapt to the stress of exercise. During recovery, the body replenishes energy stores, repairs damaged muscle tissue and strengthens muscles and connective tissue to better handle future physical demands. Without adequate recovery, the body may become overtrained, leading to fatigue, decreased performance, and increased risk of injury. Suunto GPS watches and Suunto app’s Training Zone collect and help you analyze your recovery based on indicators like heart rate variability, sleep, training stress balance and subjective feeling after workouts.   Monitor recovery with heart rate variability Heart Rate Variability (HRV) measures the variation in time between consecutive heartbeats, providing valuable insights into the balance of the autonomic nervous system and overall health. HRV is not just about heart rate but the fluctuations in the intervals between beats. A higher HRV generally indicates a more adaptable autonomic nervous system, reflecting the body's ability to handle stress effectively. Various factors, including intense training, mental stress, or illness, can influence HRV readings. Suunto Race, Suunto Vertical, and Suunto 9 Peak Pro offer HRV tracking during sleep, providing a reliable and easy way to gather comparable data. Interpreting HRV data is highly individual, and higher values usually signify better autonomic balance within an individual's normal range. Suunto defines an individual's normal range over 60 days, comparing the rolling seven-day average with that baseline. Consistently low HRV values may indicate a compromised recovery state due to factors like chronic stress, inadequate sleep, overtraining, or underlying health issues. After intense efforts or races, it's normal for HRV to temporarily drop below the normal range. Abnormally high HRV, indicated by a yellow or red warning in the app, may suggest excessive recovery (parasympathetic nervous system activity), often in response to accumulated stress. Learn more about HRV tracking with Suunto     Understand how much sleep you are getting Sleep plays a crucial role in recovery by allowing the body to repair and regenerate tissues that have been damaged during exercise. During sleep, the body releases growth hormone, which helps build and repair muscles, and the immune system releases cytokines, which fight off inflammation and infection. Additionally, sleep helps regulate hormones that affect appetite and metabolism, which can impact weight management and overall health. Lack of sleep can lead to decreased performance, increased risk of injury, and other negative health consequences. To optimize recovery, athletes should aim for at least 7-9 hours of quality sleep per night and establish a regular sleep routine that includes a consistent bedtime and wake-up time. To track sleep, you need to enable sleep tracking in the watch settings and wear the watch during sleep. In the settings, you also define your bedtime. Your watch uses that period to determine when you are sleeping (during your bedtime) and reports all sleep as one session. If you get up for a drink of water during the night, for example, your watch still counts any sleep after that as the same session. When you wake up, you are greeted with a summary of your sleep. The summary includes, for example, your average and minimum heart rate, and the total duration of your sleep, as well as the estimated time you were awake and the time you were in deep sleep. In addition to the sleep summary, you can follow your overall sleep trend with the sleep widget on your Suunto Vertical, Suunto Race and Suunto 9 Peak Pro. When you sync your watch with the Suunto app, you will see more sleep data and trends. Read about six ways to improve your sleep   Know the balance between your long and short-term training load Training stress score (TSS) is a metric that quantifies the stress training puts on your body. Over time, this load adds up. This is illustrated by Acute Training Load (ACL), the weighted seven-day average of your TSS, and Chronic Training Load (CTL), the weighted 42-day average of your TSS. CTL is also called ‘fitness’ as it indicates how much – or how hard – you’ve been training. When you compare these two cumulative training stress metrics, you get Training stress balance (TSB). If your acute load is smaller than the chronic load, your Training stress balance is positive: your training recently has been lighter than over the past several weeks. A positive TSB indicates that you are adequately recovered and may be ready to increase your training load, while a negative TSB suggests that you may need more rest or recovery time before increasing your workload. By using TSB as a guide, you can optimize your training and reduce the risk of injury or burnout. Learn more about Training stress score   Trust your subjective feelings as well Monitoring feelings after an activity can provide valuable insight into your overall recovery status. If your feelings after exercise start to trend downward, something is not right. You may be pushing too hard, not recovering well enough or might be getting sick. Consider taking a break or doing something different for a change You can add your feeling on your watch when saving an activity. You can then view the feeling trend in the Suunto app’s Training zone. The app shows your subjective, after-workout feeling for both the current week and the previous six weeks.
