Amazfit Cheetah 2 Ultra

OVERVIEW.

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.

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. HybridCharge™ Energy Intelligence brings together Training Load, BioCharge™, and LifeLoad™ to show how training, recovery, sleep, and daily demands affect your capacity over time. 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. HybridCharge™ Energy Intelligence 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

Stay Connected. Stay in Rhythm.
