Am zweiten Sonntagmorgen im März fällt in Maloja im Oberengadin der Startschuss für den Engadin Skimarathon. Die grösste Sportveranstaltung der Schweiz zieht jährlich rund 14'000 Langlaufbegeisterte aus über 60 Nationen ins Bündner Hochtal. Auf der 42 km langen Marathonstrecke bewegen sich die Läuferinnen und Läufer über zugefrorene Seen, vorbei an typischen Engadiner Dörfern und durch eine einmalige Winterlandschaft bis nach S-chanf. Seit 1969 laufen Tausende Teilnehmende am zweiten Sonntag im März die Marathonstrecke von Maloja bis S-chanf.

WattPose — The AI Cycling Coach In Your Pocket. WattPose uses your iPhone camera and on-device AI to analyze your riding position in real time — while you pedal. No sensors. Just ride. WHAT WATTPOSE MEASURES ▸ Back Angle The lean angle of your torso from vertical. Optimal: 40–60°. Too upright means more drag; too flat means back pain and power loss. ▸ Knee Extension The angle at the knee joint at the bottom of the pedal stroke. Optimal: 140–155°. Protects tendons and maximizes pedalling efficiency. ▸ Knee Stability Lateral deviation of the knee from the ideal line. A wandering knee is a hallmark of hip weakness or saddle mismatch. ▸ Hip Rocking Side-to-side oscillation of the hips. Excessive rocking wastes watts and stresses the lower back. ▸ Head Drop Your head should sit above your shoulders. Drooping signals fatigue and increases the risk of neck injury. ▸ Shoulder Symmetry Equal loading on both sides. Asymmetry reveals muscular imbalances that limit sustainable power output. VIRTUAL CdA & WATTS SAVED WattPose calculates your virtual CdA (aerodynamic drag coefficient × frontal area) directly from your body pose — no wind tunnel required. Calibrate once from your upright position, then watch in real time how many watts you save by getting more aero (calculated at 40 km/h). A lower CdA means less drag and more speed for the same effort. REAL-TIME AI ANALYSIS ML Kit runs entirely on-device (no cloud upload, no latency). The AI skeleton analyses every frame at up to 30 fps and delivers colour-coded live feedback: • Green = perfect form • Orange = minor issue detected • Red = form breakdown, correct now VOICE COACHING No need to glance at your screen. WattPose speaks directly to you: "Relax your shoulders", "Stabilize your knee", "Keep your hips still" — in your language (English & German). Mute instantly with one tap. BLUETOOTH SMART TRAINER Pair your indoor trainer via BLE (FTMS Indoor Bike Data and Cycling Power Profile supported). Live watts and cadence (RPM) feed directly into the efficiency score — giving you a fully connected coaching experience. POST-WORKOUT ANALYSIS After every ride, review: • Your Collapse Point — exactly when and why your form broke down • A personalised Action Plan with targeted exercises (e.g. Clamshells for knee stability; Plank for back and head posture) TRAINING HISTORY & PROGRESS Every session is stored locally. The Stats screen shows: • Total sessions & total training time • Average & best form score • Bar chart of your last 7 sessions • Trend analysis (improving, stable, or declining) BIKE FIT GUIDE An in-app reference that explains what each metric means, how it's measured, and why it matters — with interactive optimal-range bars for every data point. YOUR DATA, YOUR DEVICE All analysis happens locally on your iPhone. No camera data ever leaves your device. Built for road cyclists, triathletes, gravel riders, and anyone who wants to train smarter — WattPose is the personal aero coach that fits in your jersey pocket. Start riding. Start improving.
