About Marathon Coach
Marathon Coach™ — Train Smarter™ Set your goal once. Get an adaptive race training plan that appears in the native Apple Watch Workout app — no chat coach, no spreadsheets. THREE PILLARS • Glanceable — Open the app and see today’s workout instantly: distance, pace guidance, and your week at a glance. • Autonomous — Plans build and adapt from your real runs, sleep, heart rate, and training load. No typing to an AI chat coach. • Watch-native — Send your plan to Apple Watch. Workouts appear under Scheduled in the Workout app via WorkoutKit. HOW IT WORKS 1. Set your race goal, target time, and training level (~2 minutes). 2. Connect Apple Health (optional but recommended) for personalized adaptation. 3. Train where you are — Start outdoor runs on iPhone GPS from the app, or open plan sessions on Apple Watch under Workout → Scheduled. Lock the phone for Live Activity metrics while you run. 4. Weekly reviews and recovery signals adjust your plan as you train. FREE CORE The full core experience stays free: goal setup, adaptive plan, Apple Health, Apple Watch → Scheduled, outdoor iPhone GPS runs with Live Activity (time, distance, pace), weekly plan review when you open the app, and share cards. No account required for free use. MARATHON COACH PRO (OPTIONAL) Upgrade to Marathon Coach Pro for deeper coaching — daily plan tune-ups, recovery-aware adjustments after rough days, post key-workout reviews, background plan refresh when entitled, and post-run pace zone estimates on planned sessions (plan-anchored — not HR or medical zones). Subscribe in the app via Apple (auto-renewable). Manage or cancel anytime in Settings → Apple ID → Subscriptions. AI COACHING (OPTIONAL) Enable AI coaching in Settings for plan adjustments from summarized Health metrics — never raw GPS tracks. Or keep a local plan with zero server traffic. You can turn AI off anytime. SHARE YOUR PROGRESS Export branded share cards — race countdown, week in review, latest workout — as square or 9:16 Story images. REQUIREMENTS • iPhone (iOS 17+) • Paired Apple Watch (watchOS 10+) for scheduled Watch workouts • Not optimized for iPad in this version Training guidance only — not medical advice. Consult a physician before starting or changing any exercise program. Privacy: https://www.getmarathoncoach.com/privacy Support: https://www.getmarathoncoach.com/support
