Cheetah 2 Ultra is built for trail runners facing prolonged exposure in unpredictable terrain, where distance is sustained through endurance and load is carried through structure. With up to 33 hours in Trail Running mode, full-color contour maps, and a vibrant 1.5-inch AMOLED display with 3000-nit clarity under alpine light, it remains stable when effort extends beyond expectation. A Grade 5 titanium frame reinforces the watch without excess mass, refining strength through architecture rather than bulk. Advanced positioning systems ensure precision across shifting terrain, while BioCharge, HRV, and training load intelligence help manage physiological stress over time. Every element serves one purpose: to carry more distance and control more load — without compromise.
Up to 33 hours in Trail Running mode, and 30 days with typical usage, covers race day and the longest runs without compromise.
Vibrant 1.5" AMOLED display with sapphire glass for durability and clear data anytime.
Full-color contour maps and ultra-fast navigation keep you on course when terrain shifts and elevation changes.
Dual-band positioning, backed by six satellite systems, delivers accurate GPS tracking even under dense tree coverage.
64GB onboard storage powers full contour maps and offline navigation for uninterrupted training and racing.
Built-in running workouts target the foundations that matter most over distance — endurance, threshold efficiency, and strength.
Trail Running workout supports load settings, so your training data more accurately reflects true effort and helps you improve more efficiently.
Engineered for Load.
The middle frame, bottom case, and buttons are crafted from Grade 5 titanium, delivering full-metal structural integrity without excess weight. Scratch-resistant sapphire glass protects a 1.5" AMOLED display that stays clear in sunlight, at altitude, and through the night.

Trail-Ready Battery.
Engineered to sustain the full demands of an ultra-distance race, not just to last long on paper, but to operate reliably throughout the entire race environment. Up to 33 hours¹ in Trail Running mode covers the world's most demanding trail events from start to finish. Up to 30 days of typical daily use means the watch that trains with you never needs to stop between sessions.
Trail Running Mode.
Trail Running mode applies load factor calculations for gradient, terrain resistance, and vertical gain, so your effort reflects what your body actually experiences. A color-coded elevation overview maps slope difficulty across your entire route, giving you a clear view of what’s ahead and how to manage it.
Train With Data That Matters.
Know exactly how hard you're working, no matter the terrain. Gradient-adjusted pace keeps your effort consistent across climbs and descents, while running power and biomechanical metrics flag the inefficiencies that cost you miles late in a race. Lactate threshold, VO2 max trending, and finish time prediction tell you not just where your fitness stands today, but where it's headed.
Purpose-Driven Workouts.
Structured training plans cover base endurance, vertical efforts, threshold runs, and strength work to build the sustained aerobic output, descending durability, and muscular endurance that ultra racing demands.
Connect Your Training.
Import structured training plans from TrainingPeaks, Runna, and Intervals.icu automatically sync completed activities with Strava so your workouts and progress stay connected across the tools you use.
Personalized Coaching.
Adaptive Zepp Coach™ training plans guide structured progression across distances from 5K to marathon, helping you build endurance, refine pacing, and develop strength throughout your training cycle.
Manage Your Gear.
Your gear works hard, too. Track mileage and usage for running shoes, cycling gear, and other equipment alongside your training history. Manage wear more evenly and know when it’s time to rotate, replace, or tune up.
Navigate with Confidence.
Six satellite systems, a circularly polarized GPS antenna, and dual frequency positioning2 use multiple signals for precise tracking in dense forests, steep canyons, and remote terrain. Your data stays on course, so your race stays on track.
Own the Route.
Automatic Rerouting
If you move off course, automatic rerouting calculates a new path based on your real time location and destination, helping you stay focused on the run instead of the route.
Points of Interest Search
Need a quick pit stop? With offline maps³, search nearby points of interest right from your watch.
Turn-By-Turn Navigation
Get guided and stay on track with turn-by-turn directions⁴ that update in real time. Whether you're navigating rugged trails or race checkpoints, you're always headed the right way.
Route Planning
Set a target distance and direction and the watch generates optimized round trip routes, helping you explore new paths while keeping your training distance on track.
Light the Way Forward.
Dual mode LED illumination with white and red-light options improves visibility during early morning and late evening runs, with Boost and SOS modes that add confidence when training in low light conditions.
Train Smarter, Recover Better.
You don't just train hard. You recover with purpose. BioCharge™ synthesizes overnight HRV, sleep quality⁵, blood oxygen, and respiratory rate into a single daily readiness score, so you know exactly when your body has rebuilt and is ready to go again. Heart rate zone monitoring, fatigue tracking, and training load balance keep that picture complete across weeks of high-volume preparation, so you arrive at the start line ready.
Train Hybrid. Prepare Better.
Hybrid Training in the Zepp App organizes your preparation across endurance, strength, and recovery, with Weekly Structure showing exactly how your load is distributed so you can build volume without the fatigue that derails long training blocks. BioCharge™ energy monitoring synthesizes your overnight recovery data into a single daily readiness signal, and Focus translates that into a daily training recommendation — so every day of your plan serves your long-term preparation.
