Adjust run time, walk time, warm-up, cool-down, and the number of rounds to create the session that works best for you. Suggested starting levels: 30s run / 90s walk 60s run / 60s walk 90s run / 30s walk During each workout, the app can also track heart rate and save your session to Apple Health, including workout time, calories burned, and distance covered.

AI Endurance is the data-driven AI coach for running, cycling, and triathlon. It learns from your own training to build a model of you (your fitness, your recovery, your race goal), then shapes your plan around that model and adapts it every day, so you always know what to do next. WHY ATHLETES CHOOSE AI ENDURANCE • Adaptive AI training plans: Set a race goal and get a full plan that reshapes itself as your fitness and recovery change. No more rigid plans that fall apart after one bad week. • Recovery you can trust: We read your HRV, resting heart rate, and DFA a1 to tell you when to push and when to back off, so you train hard without digging a hole. • Talk to your AI coach: Ask questions in plain language. Change a workout, understand your data, or plan your week just by chatting. • See inside every workout: Power and pace curves, durability, decoupling, and drift analysis that show exactly how your fitness is changing. • Built to peak, not just predict: Most apps stop at predicting a race time. AI Endurance builds your entire plan to optimize your race-day performance, and refines it as your data changes. • Two-way sync, not just a connection: AI Endurance imports your workouts from Garmin, Strava, Coros, Polar, Wahoo, Suunto and more, and reads your recovery data from Oura, Whoop, and your watch. Then it pushes your planned workouts straight to Garmin, Coros, Wahoo, Zwift, TrainingPeaks and more, ready to train with no manual entry. FOR EVERY ENDURANCE ATHLETE Whether you're chasing a first 5K, a Boston qualifier, a century ride, or an Ironman, AI Endurance meets you where you are and grows with you. Runners, cyclists, and triathletes all train from one adaptive plan. Train smarter. Recover better. Race faster. Download AI Endurance and get a coach that actually adapts to you.
