DESIGNED FOR LONG RACES WITH A LONG LENGTH
56 g—lighter than two energy gels. Top-of-the-line features in a compact titanium case that’s comfortable to wear during both long training days and long races. Sapphire crystal—one of the hardest materials used in premium sports watches—withstands scratches from rocks and impacts from branches, so you can keep a clear view of your route, data, and navigation from start to finish.
RELIABLE ON THE GO, EVEN OFF THE BEATEN PATH
PRECISE LOCATION TRACKING
Dual-band positioning (L1 and L5) remains stable even where terrain and buildings scatter the signal. Whether in deep forests, narrow canyons, or urban routes—your route always stays accurate and your track log precise.
FREE WORLDWIDE OFFLINE MAPS
Contour lines, place names, roads, and bodies of water are downloaded to your watch and available to you for free. Complex terrain is clearly visible at a glance—and completely offline.
FASTER CHARGING. LONGER RUNNING TIME.
EXTREMELY LONG BATTERY LIFE
The Suunto Race 3S is powered by a high-density silicon-carbon battery that stores more energy in the same compact titanium case, ensuring it can handle even long trail runs.¹
CLARITY WHEN IT MATTERS MOST
TOP-OF-THE-LINE DISPLAY
1.32" AMOLED · 2,000 nits peak brightness
466 × 466 resolution with an adaptive refresh rate of 5 Hz–60 Hz · 233% brighter than the Race S.
Whether under blazing sun, deep forest shade, or in twilight—pace, route, and heart rate are visible at a glance, so you can just keep running and focus entirely on the trail.
PERFORMANCE YOU CAN COUNT ON
FASTER RESPONSE
The new-generation Apollo 510 chip offers more processing power and better energy efficiency. Map zooming, page turns, and every interaction respond instantly as soon as you trigger them.
PRECISE HEART RATE
An improved sensor and algorithm behind a 2.5D curved lens that sits closer to your skin. More light paths, better contact, fewer motion-related errors, and readings that accurately reflect your actual exertion.
SUUNTO AI COACH
ASK THE SUUNTO AI COACH
Ask the Suunto AI Coach any questions about your training. Get clear, context-specific answers with charts, tables, and maps. Create structured training sessions and routes, save them in the Suunto app, and sync them with your watch.
PERSONALIZED TRAINING PLAN
Select your running goal and let the Suunto AI Coach create a plan tailored to your goal, your progress, and your current condition.
YOUR CONDITION—ALWAYS IN SIGHT
Stress, recovery, HRV, sleep quality, and training balance all work together to show whether you’re building up, exhausted, or in top form.
TRUE INTENSITY
When you pair your Suunto heart rate strap with the watch, ZoneSense determines your actual intensity directly based on your body’s response, so your training zones adjust automatically.
SMART TRAIL RACE STRATEGY
RACE PLANNER
The Suunto Race Planner creates a personalized pace plan that takes into account the elevation changes along the race course, weather conditions, and your race goal. During the race, the Suunto Race 3S provides real-time pace guidance and shows how far ahead or behind your plan you are. This helps you pace yourself better and maintain your pace throughout the race.²
ASCENT GUIDE
Thanks to real-time elevation data along your route, you’re always one step ahead on every ascent and descent. With every glance at your wrist, you can see what lies ahead and adjust to changing terrain in time.
