Jukka Saarikorpi takes over @suuntodive Instagram
Passionate diver, photographer and Suunto’s own diving business line manager, Jukka Saarikorpi is hosting the @suuntodive Instagram account for a week, starting today. Make sure to follow to catch his inspiring images! USS Vanderberg, Florida Key West. © Jukka SaarikorpiWhere are you from, Jukka? I come from Finland. I was born in Tampere and now and live here in Helsinki. I work for Suunto as a diving business line manager. Where do you dive regularly? We tend to travel quite a bit for my vacations so most of my dives are in warm water. We also test diving products for Suunto in the Ojamo abandoned limestone mine, about 100 km from Helsinki in Lohja. There, and also in Baltic Sea, I occasionally do cold water diving. I enjoy warm water diving more and photographing marine animals. In Finland, you see a lot of wrecks, but wildlife is very rare to see while diving. © Jukka SaarikorpiWhat inspires you about the underwater world? I have always enjoyed being near the sea. I used to do a lot of competitive sailing, which I still do. Diving became something that I can enjoy in nice locations. It gives me something exciting to do in my free time. Nowadays, it has turned into work as well, but I still love it! How would you describe your photography style? I mostly use a wide-angle lens and like shooting big animals, wrecks and divers. I try to capture the moment underwater when the light conditions are changing. It makes diving more interesting when you have more challenges to get the “perfect” picture. Is there a story you wish to tell with your images? I love to inspire people to start diving and to appreciate the ocean more. The ocean is something I really value and I hope I can encourage other people to appreciate it too. Where to follow your adventures? You can see my underwater photography on my Facebook page, on Instagram and on my photography website.

The one thing every freediver needs
A dive computer makes freediving safer, more enjoyable and helps to improve performance.
Ute Gessman began freediving before the first dive computers were on the market. The AIDA sport officer and competition freediving judge would instead in those days carry a manometer (a mechanical device for measuring pressure) down with her, which was often inaccurate.
Since then, dive computers have become a must for every freediver, she says.
“For freediving, you need a freediving computer,” she says. “Without one, you have no idea where you are.”

Here’s why a dive computer is essential kit.
Safety first
A dive computer can tell you how long you’ve been under the water, your depth, and when you must return to the surface. It also helps your buddy at the surface to keep track of how your dive is going. “I can see when he or she left the surface, how long they’ve been under and when he or she should reach the bottom,” says Suunto’s dive business line manager, and freediver Jyri Vehmaskoski. “A dive computer also tells me when I should go down to do the safety dive, about 10 or 15 m, to make sure they’re okay as they come up.”

Preparation
“A freediving computer helps you prepare on the surface for a dive,” Ute says. You can use the dive computer to time different breathing exercises, to keep track of your warm up dives, and to tell you when you should commence the dive.”
Suunto D4i Novo is a lightweight dive computer that has four diving modes, including freediving.
Overcoming anxiety
“When most people start freediving, they are a little bit afraid to use the free fall to go down the whole way,” says Ute. “Using a dive computer helps them to relax because it tells you how long you should descend before turning back. “Some people want to work by a time, so they put a dive time in, so they know when two minutes, for example, has passed then they need to go back.”

To manage dive stages
Jyri uses his dive computer to manage the difference stages of a dive. “There are four stages when I dive deep: the first stage is obviously on the surface. I make three stronger kicks to get the dive going with momentum and then I start to relax after that. The second stage involves kicking very slowly, focusing on relaxation. Third stage: I do mouth-fill at about 24 to 27 m (an equalization technique). I set an alarm in my dive computer to mark that. The fourth stage: I stop kicking between 30 and 40 m because my lungs are squeezed and I have negative buoyancy so I don’t need to kick. I use a sound on my computer to signal this. Then I just shut my eyes, relax and do the free fall. During free fall my dive computer notifies with sound at certain depths so I know where I am at.”
After the dive
A dive computer records each and every dive in a session so once you’re back on land you can inspect the profile of each one. “The profile shows you if you had a good or bad start, if you took too long to go down, when you might have had equalization problems, whether you dived straight, down, or if you had problems,” Ute says. “You can make the profile really big so you can see every second. You can see exactly how you went down and back again. It gives a lot of information for improving performance.”

How to smash a stage trail race
Trail runner Rene Unser tells us what it takes to keep going during a multi-day race.
Image: Klaus Fengler (Feature image: Schneider Outdoor Visions)
Five-time Trans Alpine Run competitor and coach Rene Unser is passionate about trail running, in particular partnered staged races. No wonder, as she fell in love with the sport after her would-be husband coaxed her from the roads and onto the trails. She never looked back and she shares some of that passion here, as she explains what’s needed to smash a staged run.
Strategy is key
Having a fine tuned strategy is something important to Rene, in fact it’s one of the things she loves most about these races. She says: “I enjoy the strategy involved in preparation, racing and recovery. The preparation forms my lifestyle and it’s the favourite part for me.”
Care for your partner
Being in sync with your partner could make or break a race. Rene says: “Learn to work with your partner on and off the trails. Very rarely will you and your partner feel good at the same time. You need to work together and understand what the other needs.” Image: Klaus Fengler
Perfect your pace
Can you keep that pace through the whole race? Rene says you need to find out: “Learn your pace and check in with yourself – can you sustain this pace for the whole race, for many days. Try splitting your race into half and run the first half at a moderate, comfortable pace. After the half way mark you can reassess your capability to increase your efforts as you get closer to the finish.”
Know your strengths
No one has a perfect race, and that’s ok. “Most people will learn their strengths and weaknesses as their training progresses. Know there will be stages that won’t always match your strengths,” says Rene. “Do research on the daily profiles and recognise when the terrain will complement your strengths and try to capitalise on this,” she adds.
Get started
Perhaps not an eight-day trail run, but get out on the trails. Rene says: “I really encourage people if they love running long distances to give it a try. Stage races bring the world together, and I’ve met so many people and travelled to so many amazing places, it’s more than just a race!” And road runners should start slowly, she adds: “It’s a good idea to learn technique from a coach to avoid injury or join a running club to learn from others. Often the first thing I tell road runners when they make the transition to trails, is to change their mind-set, as we do a lot more hiking and road runners are not typically used to this.”

FOUR MYTHS ABOUT ULTRA-RUNNING THAT YOU NEED TO KNOW

Kilian Jornet’s game plan for speed ascent of Everest
Suunto ambassador Kilian Jornet is acclimatizing in the Himalaya so he can attempt to set a fastest known time (FKT) record on the highest mountain in the world – Everest. We caught up with him and found out the game plan for his daring project.
It’s literally the “high point” of his Summits of My Life project – alpinist, runner and adventurer Kilian Jornet’s personal mission to set ascent and descent records on the most important mountains on the planet, culminating with Everest.
Denali, Mont Blanc, the Matterhorn, Aconcagua, Kilimanjaro – all have seen records fall to Kilian. But now he’s readying himself for the ultimate challenge.
He has been preparing for months. Intense training, sleeping nights at 4500 m in the European Alps, and now he's in Nepal, doing the same at 6000 m.
“The highest I have been is 7700 m,” Kilian says. “I was feeling good then, but there is a big difference after 8200 m and after 8500 m.
“It’s really important to be well acclimatized to around 6000 m. So I will spend many nights at around this altitude. And then it’s important I go to around 8000 m before the attempt.”
Kilian and his team has arrived in Kathmandu and is getting ready for the expedition.
Depending on how well he acclimatizes, Kilian expects to make a FKT (fastest known time) attempt around mid September. It also depends on weather and snow conditions.
The plan is a light and fast, alpine-style ascent. He will carry only what he can fit a backpack. To keep weight down, he and his team have designed light, but warm boots made for purpose. He won’t be fixing ropes or using supplementary oxygen on the ascent. He will attempt the ascent from the north side, via either Norton-couloir or Horbein-couloir depending on conditions.
Two previous ascents are in the back of Kilian’s mind as time references. The first is a speed record set by Italian mountaineer Hans Kammerlander in 1996. Hans climbed from Base Camp to the summit of Everest via the North Col in 17 hours. The second reference is an “unprecedented and unrepeated” ascent in 1986 by Swiss climbers Erhard Loretan and Jean Troillet. They climbed the North Face via the Hornbein-couloir in a single alpine-style push without oxygen, ropes, or tents and descended again – all in 43 hours.
“It’s good to know these times as a reference for pace at altitude,” Kilian says. “I will take this as knowledge and will see how far I can go."
“It’s a big mountain, and we have a long term perspective. We will try this year, but probably we will need to come again next year."
“You need to go for it so if conditions are good and if I’m feeling good, I should try. But it’s important to have the patience to wait for this good moment.”

This is how Kilian Jornet prepares for Everest
This summer Kilian Jornet takes on the challenge of climbing Mount Everest, the final peak in his Summits of My Life project. Kilian will try to establish a record for the ascent and descent by a little-used route on the north face of the world’s highest mountain. To be ready for the challenge, he has spent a lot of time high in the Alps. Here are two of his training days on the Mont Blanc massif.
Physical training in the Alps: 6500 meters of climbing. (10.7.)
Kilian Jornet is taking on Everest with the purist and minimalist philosophy that is the trademark of the Alpine style. This means that, as with other challenges in the Summits of My Life project, he intends to complete the ascent in one go, without stopping at high-altitude camps. This is different from the classical Alpine approach but he has also acclimatizing himself in a different way. Kilian Jornet and his team intend to spend the last few weeks before they go to the Himalayas at a high altitude in the Alps.
Kilian’s training day high up on Mont Blanc Massif with over 3500 meters of climbing. (25.7.)
"It’s a new approach to acclimatization. Before we set off for the Himalayas we will have partly acclimatized having spent some days at altitude. This means we won’t have to wait so long to start when we arrive at the Everest base camp,” explains Jordi Tosas, Kilian’s teammate on Everest.
"This means we’ll be stronger when we begin the ascent. It can make you weaker if you spend several days acclimatizing yourself on the mountain. With this type of acclimatization we can begin the challenge with more energy and a better chance of success,” Kilian adds.

5 invaluable staged trail race training tips
“Commit to the training before you commit to the race” – Trail runner, Rene Unser.

Canadian Rene Unser, who will race the Gore-Tex Trans Alpine Run for the sixth time this year, is a trained coach with 13 years experience. She has also put together the official training plans for the epic Alpine race. So if anyone can give some helpful training tips it’s Rene, here’s what she had to say:
Commit to training
“Commit to the training before you commit to the race,” says Rene. She knows how big a time commitment a long distance race can be. A training schedule is also key, she adds: “To be successful it’s important to build up slowly, and train consistently. Find a training schedule that works for you and really dial that down.”
Mimic the race terrain
Do you know whether you’ll be running on hills or flat? Find out says Rene: “Mimic the terrain you will find during the race as much as you can! This can be hard for people who don’t live near the mountains, but it’s worth travelling to get there when you can."

Test your equipment
“Test your equipment and spend time running with your bag packed as it would be during different stages,” says Rene. All races are different, with some equipment being mandatory, she adds: “Learn how to use poles efficiently if they are permitted in your race, and if you choose to use them.”
Get your nutrition spot on
Of course fuelling before and after a race can make a huge difference, and Rene works with what she’s given in any particular race. She says: “I train with Hammer Nutrition Perpetuem with water and Hammer Gels. Before a race I start to practice with the food I’ll get at the aid stations. For TAR this is salami, cheese and cake. I am able to supplement with what’s provided if I have my staples. I aim for 120 to 150 calories an hour during a race.”
Take it easy
“A lot of people will cram a lot of races into a season, and it’s natural to want to do this,” says Rene. But try not to, she adds: “They want to squeeze in a 50k race as that’s what one stage in the race might be like. I caution all my athletes training for races like TAR not to have too many late season races, as it uses up valuable training time, by the time you factor in your taper and recovery.
