Amazfit Unveils the Cheetah 2 Ultra: The Performance Trail Running Watch Built to Master the Toughest Mountain Trails

Key Terms

hrv medical

Heart rate variability (HRV) is the tiny, millisecond-by-millisecond variation in the time between consecutive heartbeats, measured by ECGs or wearable sensors; it reflects how the nervous system balances stress and recovery. Investors care because HRV is often used as a health signal in devices, apps and clinical claims — like a dashboard light showing how well the body’s control systems are working — which affects product credibility, regulatory scrutiny and market demand.

amoled technical

AMOLED is a display technology where each tiny pixel lights itself with organic materials and is switched on and off by a thin control layer — think of a high-resolution mosaic of tiny self-lit bulbs that produce deep blacks, vivid colors and fast motion. Investors care because AMOLED affects product appeal, battery life, production cost and supplier dynamics; choices around this screen tech can influence sales, margins and capital spending across device makers and component suppliers.

gps technical

A global network of satellites and ground stations that provides precise location and time information to devices on Earth; think of it as a map and clock in the sky that tells a device exactly where and when it is. Investors care because GPS underpins navigation for shipping and delivery, fleet and asset tracking, location-based services, autonomous vehicles, and precise timing for financial networks—so changes in GPS technology, reliability, or competing systems can affect revenue, costs, and risk across many industries.

lactate threshold medical

The lactate threshold is the exercise intensity at which the body starts producing lactate faster than it can clear it, causing a sharp rise in fatigue and breathing effort. Think of it like a car hitting a point where the engine works harder and performance drops; measuring or shifting this threshold is important to investors because it is a clear, measurable biomarker for sports performance products, diagnostics, drugs, and wearable devices that can drive sales or clinical value.

Built for ultra distances and mountain racing, the Cheetah 2 Ultra combines long battery life, precision navigation, and advanced training insights to carry more distance and control more load

MILPITAS, Calif.--(BUSINESS WIRE)-- Amazfit, a leading global smart wearable brand owned by Zepp Health, today announced the Cheetah 2 Ultra. Building on the momentum of the recently launched Cheetah 2 Pro—designed for road marathoners—the Ultra is a specialized instrument for trail runners who measure success in elevation, unpredictable terrain, and hours spent on the move.

Built for ultra distances and mountain racing, the Cheetah 2 Ultra combines long battery life, precision navigation, and advanced training insights to carry more distance and control more load.

Amazfit’s Cheetah 2 Ultra is built for runners who prepare for ultra distances and mountain races, boasting 33-hour trail running optimized GPS battery life, full-color contour maps, Grade 5 titanium construction, and advanced training and recovery insights. Amazfit designed the Cheetah 2 Ultra to support the preparation required for long-course mountain racing from start to finish.

Engineered for Distance, Structured for Load

In ultra-running, distance is sustained through endurance, but load must be carried through structure. The Cheetah 2 Ultra pairs a Grade 5 titanium bezel, frame, and back cover with scratch-resistant sapphire glass to deliver exceptional structural integrity and strength without adding unnecessary weight. Built to withstand the rigors of technical mountain trails while remaining light on the wrist, the watch features a vibrant 1.5-inch AMOLED display with up to 3,000-nit peak brightness for clear readability from early alpine starts to late mountain finishes. A built-in dual-mode flashlight, with adjustable white, red, SOS, and Boost modes up to 300 lux, adds confidence during early morning and late evening efforts in the mountains.

Trail-Ready Battery Life That Matches the Distance

Built to support long stretches of training and racing, the Cheetah 2 Ultra offers up to 33 hours of battery life in Trail Running Mode, with the always-on display, heart rate monitoring, dual-frequency GPS, all-satellite positioning, and map navigation enabled. Off the trails, users can expect up to 30 days of typical battery life, helping the Cheetah 2 Ultra keep pace with both training cycles and daily life.

Navigate with Confidence Across Any Terrain

The Cheetah 2 Ultra delivers precision navigation built for the complexity of mountain racing.

• Dual-frequency six-satellite positioning: A circularly polarized GPS antenna ensures accurate, dependable route tracking through dense forests, steep canyons, and technical terrain.

• Alpine-Ready Clarity: A vibrant 1.5-inch AMOLED display protected by scratch-resistant sapphire glass features 3,000-nit peak brightness, making data easily readable under the intense glare of high-altitude sun.

• Full-Color Navigation: Topographic and contour maps deliver responsive navigation with rendering speeds 2.5 times faster and refresh speeds 12 times faster than before. Runners can create point-to-point routes, search nearby points of interest, and automatically reroute without needing a phone or network, so navigation stays reliable when focus and terrain demand the most. The upgraded Trail Running Mode includes a new elevation overview that color-codes slope difficulty across the entire route, giving runners a clear, at-a-glance view of what’s ahead and how to manage it. Trail Running Mode also applies load factor calculations for gradient, terrain resistance, and vertical gain, so exercise data reflects the true intensity of mountain effort.

Train Hybrid. Prepare Better.

Hybrid Training in the Zepp App organizes preparation across endurance, strength, and recovery, with Weekly Structure showing how training load is distributed so athletes can build volume without the fatigue that derails long training blocks. BioCharge™ energy monitoring translates overnight recovery into a daily readiness signal, while VO₂ max, fatigue level, training status, HRV, sleep, and training load insights help runners understand when to push forward and when to recover. Focus turns those signals into a clear training recommendation, helping each day support long-term progress.

With Cheetah 2 Ultra capturing performance in the moment, the system extends from preparation into execution, connecting how runners plan, perform, recover, and adapt over time.

Metrics That Define Progress Over Distance

The Cheetah 2 Ultra translates training data into meaningful guidance for mountain runners. Advanced running metrics, including lactate threshold, running power, pacing analysis, gait tracking, and finish time predictions, give runners a clearer understanding of how they move and how they can improve. Ground contact time and posture tracking add biomechanical depth to help runners train with greater intention across demanding terrain.

For those seeking deeper control, the watch integrates with advanced third-party platforms including TrainingPeaks, Runna, and Intervals.icu, while syncing activities with Strava. With 64GB of onboard storage, the Cheetah 2 Ultra also supports over 100 hours of podcasts and additional mapping.

"The Cheetah 2 Ultra is built for trail runners facing prolonged exposure in unpredictable terrain," said Wayne Huang, CEO of Zepp Health. "By focusing on a 'Structured for Load' design, we’ve refined strength through architecture rather than bulk, creating a tool that supports the runner from the first mile of preparation to the final meter of the race."

Pricing and Availability

The Cheetah 2 Ultra will be available for purchase starting May 13, 2026, for $599.99 on Amazfit.com.
