How to use Karoo 2 bike computer with Suunto
First things first: connect your Karoo 2 with your Suunto account
To get started, connect your Suunto and Hammerhead accounts: Go to dashboard.hammerhead.io and select ‘Suunto’ under ‘Accounts’. Once connected, your rides are automatically synced from your Karoo 2 to Suunto app and the routes planned in Suunto app are synced to your bike computer for navigation. After connecting you will also get access to Suunto cycling heatmaps on your Karoo 2.
If you don’t have a Suunto account yet, download Suunto app from the App Store or Google Play and create one. If you need a Hammerhead account, go to dashboard.hammerhead.io

See the heatmap on your bike computer
Suunto heatmaps show the most popular rides near you – or at your travel destination. They are great for route planning in Suunto app and offer clear benefits out on your rides as well.
On a Karoo 2 bike computer you can see Suunto cycling heatmaps on the go. So, even without a pre-planned route you will find places to ride. The more the road glows, the more popular the ride has been amongst the Suunto community. And, once it is time to turn back, your Karoo 2 will help you navigate back home!
Learn how to get Suunto heatmaps on your Karoo 2.
Plan routes for your rides in Suunto app
Suunto app has advanced route planning functionalities that you can use even on the go.
When planning a route, toggle between different map layers, 2D and 3D maps and use heatmaps to get inspiration. As you create your route, the app will calculate the distance, vertical meters and estimated duration. That way you can keep track of how long and challenging your route might be.
Once saved the routes are synced to both your Karoo 2 and Suunto watch for navigation. That is super handy especially if you are on a multisport adventure; ride to the mountain navigating with Karoo 2 and continue the hike up with your Suunto watch.
Use the same heart rate belt with your bike computer and watch
The Suunto Smart Heart Rate Belt provides accurate heart rate data without compromising comfort. You can use the same belt with both your Suunto watch and your Karoo 2 bike computer. Just pair it with each device and once you are starting your activity, the belt will be connected. Note that the belt can communicate only with one device at a time. However, no pairing and re-pairing is needed.
See all your rides, runs, skis, climbs and all other activities in one place
You can review your rides recorded with Karoo 2 and all of your activities recorded with Suunto watches in the Suunto app. Your Karoo 2 rides are automatically synced after finishing the activity. Select the default privacy setting of your rides in Suunto app settings (private, your followers, public). You can also change this setting for each activity.
Analyse your progress
Suunto app’s long-term analysis view tracks your training load and helps you stay in balance – whether that means progress, maintaining your fitness or avoiding over-training. With long-term analysis tools powered by TrainingPeaks and all your Karoo 2 rides and Suunto activities in one place, you can now manage your training better than ever.
Learn more about managing your training load with Suunto app.
View your personal heatmap
As you collect data in Suunto app you are building a powerful navigation tool for yourself: My Tracks. My Tracks is a map layer that shows your own activities on the map. That is an awesome way to see where you have been or – when compared with the general heatmap – where you have yet to explore.
My Tracks is also a powerful tool to support your route planning. When re-visiting an area and planning new routes, it helps a lot that you can see your previous rides on the map as well.
View activities as 3D animations
In addition to planning and reviewing your tracks on a 3D map in Suunto app, you can even enjoy your adventures as 3D video animations: Simply go to your activity, hit the play button, and enjoy the views as you climb up mountains, go over passes and storm down winding roads. Share the link with your riding buddies and they will be able to see the 3D animation as well – even on a big screen.
Create an adventure logbook
Having all of your activities in Suunto app will enable you to build an adventure logbook. Add descriptions, photos and videos to your activities and find them later with the search tool.
You can also share the images added in your activities with data overlays: hit the share button, select an image, and customise the data fields to support your story!
Connect with hundreds of 3rd party services
Suunto is proud to have a wide array of partners it cooperates with. From route planning services to training and coaching platforms and more, you are likely to find a service that can enhance what Suunto app offers you. These partner services are now compatible with your Karoo 2 activities as well.
To learn more, go to your profile page in Suunto app and select ‘Partner services’.
Each new Suunto watch comes with a extensive Suunto Value Pack, a collection of benefits and treats offered by Suunto partners. Value Pack deals vary from premium trials to free training plans and discounts from partners like Strava and TrainingPeaks.

Suunto is proud to be an official partner of the Golden World Trail Series 2022 that’s kicking off on May 29 with the legendary Zegama-Aizkorri trail marathon in Spain, and is followed by five more high profile races around Europe and the US that culminate in a grand finale on the island of Madeira.
“We are thrilled to partner with the Golden Trail World Series and be part of the most exciting trail races of the summer,” says Antti Laiho, Suunto global brand marketing manager. “With the new SuuntoPlus Race guides we can also support the competitors in a new, helpful way.”
What makes it special
These iconic races are the ones every runner wants to experience. This, and a clear and simple format where each runner’s best three results from the six races count, make the series easier for the public to follow and get behind. Each year the Golden Trail World Series will choose a very special race for the Grand Final In 2022, the top 30 men and women from the overall ranking after the sixth race will be invited to the Madeira Ocean Trails stage race grand final. This guarantees epic action until the very last finish line.
Supported by Salomon, the series is special in many other ways. “In trail running nowadays there are many series, world championships, the European championship and so on so nobody really knows what is going on,” says Philipp Reiter, the Global Community Manager Salomon - Trailrunning.
“The Golden Trail World Series is different because it has the best athlete field in the world and supports athletes regardless of brand sponsor to join the competition, it pays travel expenses to get them to the races and there is equality between men and women in terms of prize money, visibility, media coverage, which is pretty unique. And the prize money is really high. The goal of the series is to bring trail running to a larger audience and to grow the sport, not just promoting it to the core community as is the case so often.”

7 nations, 7 highest summits, 5 days
Watch how Philipp and Adrian's project unfolded!
Reaching the summit of Mont Blanc took everything Philipp and Adrian had in the tank. They began their climb of the highest mountain in the European Alps at 01:30 AM and, even though they had worked on acclimatization, they suffered on their way up and faced icy conditions. The ski down, involving crossing crevasses, took a brutal three hours.
“When we arrived back at the car 11 hours and 30 minutes after we had set out we were both super done,” Philipp says. “We both had headaches and had to travel by car for two and a half hours to Zermatt, sleep for two to three hours and get up at 2 AM to start over again to climb Dufourspitze.
“It was crazy, because for many mountaineers just doing one of the highest summits in the Alps is a big achievement, but we climbed seven in five days. For me, it’s still unbelievable because it happened so quickly that it hasn’t really sunk in yet.”
The 7 summits project
They started their adventure on March 26 at 06:00 AM, first climbing Italy’s Gran Paradiso. The goal was to climb the highest summit in each of the seven alpine nations - Italy, France, Switzerland, Liechtenstein, Germany, Austria and Slovenia - in seven days. However, weather forecasts predicted snow and harsh conditions on the last two peaks, leaving Philipp and Adrian no choice but to do all seven summits in five days, in this order:
March 26: Gran Paradiso (4061 m), Italy. March 27: Mont Blanc (4807 m), France.March 28: Dufourspitze (4634 m), Switzerland.March 29: Vorder Grauspitz (2599 m), Liechtenstein.March 29: Zugspitze (2962 m), Germany.March 30: Grossglockner (3798 m), Austria.March 30: Triglav (2864 m), Slovenia.
The project was a year in the making and originally involved a team of four, but a sickness and a death in one of the team’s families meant two of the four had to withdraw at the last minute, leaving Philipp and Adrian to scramble to keep the project from collapsing. To avoid piling pressure on themselves, they decided to keep their goal quiet until they reached the summit of Liechtenstein’s Vorderer Grauspitz.
Battling the conditions and sleep deprivation
They realized they needed to climb all seven summits in five days rather than seven after climbing Vorder Grauspitz and seeing a weather forecast predicting snow in the Alps. At that point, it was full steam ahead, with little time for rest and recovery. They only slept 14 hours over the five days, which included napping in the car - with damp clothes and cold bones - while driving from one mountain to the next.
“We had to be really focused because of the route navigation,” Philipp says. “We followed the tracks on our Suunto watches. This helped a lot because it gave us confidence and saved time.”

Follow this mountain race training program
Available for free on Training Peaks, a Suunto training plan designed by former world champion mountain runner Max King is designed to prepare trail runners for a 20 to 50 km race with 1500 m+ of vertical ascent.
Trail runners at any level can benefit from it, but it’s best suited to those with some trail experience who are looking for the next challenge. With the help of SuuntoPlus Guides, you can now follow this training plan on your Suunto watch. When your Suunto app and Training Peaks accounts are connected, the workouts planned in TrainingPeaks will appear automatically in your watch, ready for real-time guidance. This is especially useful with structured workouts, like the hill workout in this program that has uphill intervals of various durations. Learn more about SuuntoPlus Guides here.
“A moderate level trail athlete with some base fitness will be able to handle the challenge of the increasing vertical and volume,” says Max, the winner of the 2011 World Mountain Running Championships. “The important thing with this training program, like any program, is to listen to your body. It’s easy to overdo the amount of vertical gain if you’re a fit athlete, but your body isn’t used to how hard it has to work to go uphill or the increased pounding it takes on the downhill. Be careful of small injuries that creep in. Take care of them with self massage and rolling so they don’t become a bigger issue.”
Max, 42, is a professional coach and organizes trail running camps in the US. He’s currently preparing for his own busy racing season, including the Breakneck Point Trail Marathon in New York in April to try to qualify for the US National Mountain Running Team. Then he’s heading to Spain to compete in the Zegama Marathon in Spain to kick off the Golden Trail Series.
“My philosophy in training is that running is running and as long as you lay a good foundation of base work then you’ll be able to accomplish anything with a little specific work,” Max says. “Hard work and smart decisions result in accomplished goals. This plan is meant to take that good base fitness and apply specific mountain skills to round out an athlete to be able to accomplish a mountain race.”

Vertical Week competition winners
One of the reasons we’ve continued pushing World Vertical Week every year since its inauguration in 2016 is because it brings out the best in our Suunto community. People get outside more and push themselves, and many do some truly big days.
The World Vertical Week competition captures some of the best of it. We look forward to scrolling through all the images the community shares and tags via #verticalweek. Thanks to everyone who participated in this spring 2022 edition.
As always, we selected three winners who will each receive a Suunto 9 Peak. Congratulations!
And the winners are …
Everesting the Bastille in Grenoble
You can’t get a much bigger day than what @danielott_atalps pulled off in Grenoble, France. He competed in the second edition of the Everstille 2022 and was one of four people who climbed the Bastille hill above the city 33 times, adding to 8848 m, the height of Mt Everest.
“I read about Suunto vertical week last year and was fascinated by the concept of trying to accumulate as much elevation as possible,” Daniel says. “I wanted to participate then, but it always fell on the week of my exams, so I couldn't participate. This year, I was thrilled that the Everstille, the everesting race I did, fell in the time frame of the vertical week, so I signed up immediately.
“Everestille is a race organized by Tri-Haut, an association based in Grenoble that aims to improve the waste management in the Khumbu Region below Everest. The goal of the race is to run the Bastille, as many times as possible.”
Love in the Swedish mountains
Mother Nature turned it on for @josefintrogen on a ski trip in the Sälen ski resort in Sweden. It was the first time she participated in World Vertical Week and probably won’t be her last.
“We went cross-country skiing and downhill-skiing and it was a perfect weekend with sunshine, snow and what we call ‘Sweden’s fifth season’ or ‘spring-winter’,” Josefin explains. “It basically means there’s still enough snow to go skiing without problems, but warm enough to ski in a base layer only (this weekend it was about +10°C). Every day we bought soup for lunch and made a couch in the snow to enjoy it out in the sun before continuing our tour.”
Passionate mum and daughter skimo team
Her first Vertical Week, @monivieregg took her six-year-old daughter out into the Bavarian mountains on a skimo tour. The ascent is always challenging because Monika has a small frame and pulling her 20 kg daughter up the mountain behind takes everything she’s got.
“We life very close to the Alps and the tour in the pic was at a former ski slope, called Blickner Alm at the Hochfelln,” Monika says. “My daughter really loves skiing uphill and she did a very, very good job downhill. At every carve she did I could hear a ‘hui’, ‘nice’ and ‘yipee’. She had a few falls, but after every one she got up and told me nothing happened, ‘keep going faster I want to ski on’. We both are really satisfied after a tour and we look forward to the next one.”
