Find the coordinates. Start the race.  For 90 years Suunto has been creating tools for people who explore the world beyond the ordinary. To celebrate this milestone, we are inviting adventurers everywhere to take part in a global challenge. 
 Throughout the anniversary year our elite athletes will hide special Suunto chests in environments that represent their natural playground – from alpine mountains and northern wilderness to deep forests, open water, and vibrant city landscapes.  When a chest is hidden, the coordinates are released to the world. From that moment the race begins.  Anyone can join the challenge. 

The mission is simple: reach the location first. The first person to physically arrive at the chest wins the prize inside, while the next explorers to reach the location will receive runners‑up rewards. Every challenge will take place somewhere different. 
Some locations may be remote. Some might be closer than you think. But every one of them will invite you to step outside, explore new terrain and follow the coordinates to adventure. The Suunto 90 Challenge is our way of celebrating nine decades of exploration – by inspiring people around the world to get outside and discover what adventure means to them.   Sign up for coordinates How the challenge works: 1. Sign up below: Subscribe to Suunto newsletter to be the first to hear when new coordinates are released. 2. Get the coordinates: When a Suunto athlete drops a chest somewhere in the world, we will release the coordinates in our newsletter and @suunto Instagram – and the race begins! 3. Start the race: From that moment anyone can attempt to reach the location. Plan your route, prepare your gear and start moving. 4. Find the chest: The first explorer to reach the chest wins the prize inside. The next explorers will receive runners-up rewards.

For years, Suunto athletes, adventurers, and creators have pushed our products into new places — testing limits, exploring new ideas, and imagining new tools for training and exploration. Now, we’re opening those tools to the community. Introducing Open SuuntoPlus™ – a new way for developers, athletes, and the wider Suunto community to build their own Sports Apps for Suunto watches.  What is Open SuuntoPlus™?  Open SuuntoPlus™ is a new way for your Suunto watch to gain features created directly by the community.   SuuntoPlus™ Sports Apps are tools that run on your watch during activities, adding new features and insights that enhance your workouts, training sessions, and outdoor adventures.  With Open SuuntoPlus™, developers, athletes, and the wider Suunto community can now create these apps themselves.  New Sports Apps appear in the SuuntoPlus™ Store in the Suunto app, where you can choose free tools that support your training needs.   By opening the platform, new ideas can arrive faster than traditional firmware updates — and continue evolving over time.  What can creators build?  With Open SuuntoPlus™, creators can bring a wide range of ideas to life — from sport-specific tools to new ways of analysing and interacting with training data.   SuuntoPlus™ Sports Apps can include:  Sport-specific tools designed for unique workouts or race conditions  Performance features such as pacing logic, intervals, or threshold calculations  Sensor integrations using Bluetooth Low Energy devices  Real-time insights calculated during activities  Creative tools for navigation, exploration, or gamified training  Whether the goal is deeper performance insight or a completely new training experience, creators can extend their Suunto watch in ways that suit their sport and style.  Examples from the community  Some early SuuntoPlus™ Sports Apps already demonstrate what the community can build. You can see several of these in the video above.  Early examples include:  ParkRun tool – displays a QR code on your watch for ParkRun event registration.  Rugby referee app – helps referees track match time, scores, and game flow during matches.  Tennis Pro – allows players to track points during a tennis match.  Hex Hunter – a gamified app that rewards athletes for exploring new areas.  Beer Mile – a playful app designed around the well-known running challenge.  What this means for athletes  Open SuuntoPlus™ brings more flexibility and faster innovation to your Suunto watch.   For athletes, it means:  More sport-specific tools created by the community  New features arriving faster than traditional firmware updates  More ways to personalise your watch for your training style  Ideas coming directly from athletes and developers  How it works  Open SuuntoPlus™ makes it possible for new ideas to move from concept to wrist quickly.  Creators build SuuntoPlus™ Sports Apps using the SuuntoPlus™ Editor, where apps can be developed, tested, and refined.  Once ready, apps can be submitted through the Suunto Partner Program and reviewed by Suunto before appearing in the SuuntoPlus™ Store.  From there, athletes can discover and download these apps directly in the Suunto app — and creators can continue improving them with updates over time.  Get started  As Open SuuntoPlus™ grows, more Sports Apps will continue to appear in the SuuntoPlus™ Store.  Explore the available apps in the Suunto app to discover new tools that support your training, sports, and outdoor adventures.  If you’re interested in creating your own SuuntoPlus™ Sports App, you can learn more, and get started by joining the Suunto Partner Program.  Learn more about Open SuuntoPlus at Suunto Api Zone

Suunto Ambassador Sarah Perry ran an incredible 637 km in 95 hours at the Big Dog’s Backyard Ultra in Tennessee, breaking the women’s world record. A maths teacher and mountain rescue volunteer from Cumbria, England, Sarah is known for her love of long days on the fells – usually with her dog in tow. But even with years of endurance running behind her, this achievement was something else entirely. “It was the most epic experience,” Sarah says. “I enjoyed every minute and was so grateful to be there. There were serious lows – the heat, sickness, IT band pain – but so many highs too. I loved meeting the other competitors and running further than ever before.” Big's Backyard Ultra was Sarah’s sixth Backyard Ultra, and experience clearly paid off. The event’s unique format – a 6.7 km (4.167-mile) loop every hour on the hour until only one runner remains – requires not just fitness, but faultless pacing and mental resilience. This distance ensures that if a runner completes one lap every hour for 24 hours, they cover exactly 100 miles in a day. “The key is to simply run the lap that you’re in and not think about the bigger picture,” she explains. “You have to manage the small problems and trust that things will get better – and often they do.” As laps turned into days, Sarah’s sleep strategy became a critical part of her success. “I mastered sleeping this time,” she says. “I’d run the night loop, then come in with enough time to eat, drink, do any other admin, and grab a few minutes of sleep. Even a three-minute nap every hour can work wonders!” Her focus never wavered – even after surpassing the previous world record. “Once I’d broken the record, I was really focused on making it to 100 yards,” Sarah says. “I still had it in my legs and head to keep running but a back issue stopped me. I was disappointed but proud.” [Editor’s note: a yard in Backyard Ultra jargon refers to a full 6.7 km loop.] Throughout the race, Sarah relied on her Suunto Vertical 2 – and the Backyard Ultra SuuntoPlus feature – to manage pacing and timing. “I loved the Backyard Ultra feature,” she says. “All I need to know is how far I have left in each loop and how much time until the next lap. It’s perfect.” Sarah is still soaking up the experience and the fact that she is now the world record holder.  “It feels slightly surreal and hasn't really sunk in yet! I always have a variety of goals – number one was to get a PB and then I hoped I could aim for the women's record. I would love to run 100 yards, so this will be my next challenge!” Follow Sarah on Instagram Sarah Perry’s Big Dog’s Backyard Ultra in numbers Laps: 95 (New World Record) Distance: 637 km / 396 miles Total duration: 95 hours Total running time: 81:07:08 Fastest lap: 39:53 Average lap: 51:13 Calories: 37,537 Steps: 822,107 Sleep: No data available Watch: Suunto Vertical 2 Battery consumption: 87% (13% at finish)   All images by Jacob Zocherman / @searchingforzocherman

In ultra running, the crew is often the unsung hero. Crewing tells the story of Martina Valmassoi and Dakota Jones as they switch roles between athlete and supporter across two demanding races. Through La Sportiva Lavaredo Ultra Trail by UTMB in Italy and HOKA Val d'Aran by UTMB in the Pyrenees, Martina and Dakota experience both triumph and heartbreak. When Martina’s race in her home mountains takes an unexpected turn, Dakota is there to guide her through disappointment. Just a week later, the roles reverse as Martina helps Dakota push through doubt and exhaustion toward a hard-earned top-10 finish.  The film captures the resilience, trust, and deep connection that remind us: trail running is never just a solo sport. Along the way, you’ll also pick up insights into the art of crewing – valuable lessons you can bring into your own races or when supporting others.
