CoachX is a running-specific AI coach that connects to your sports watch (via Intervals.icu), analyzes your training data including HRV, heart rate, and sleep, and generates personalized running training plans using proven coaching methods from Daniels, Hansons, and Pfitzinger. You can chat with your running-specific AI coach to adjust workouts in real-time.

Which sports watches does CoachX support?

CoachX works with any sports watch supported by Intervals.icu, including Garmin, Wahoo, COROS, Polar, and Suunto. Your training data is synced automatically, and AI-generated workouts are pushed directly to your watch.

How does AI coaching work?

CoachX uses the latest AI models combined with established coaching methodologies (Daniels VDOT, Hansons, Pfitzinger). The AI analyzes your fitness data, training history, and goals to create periodized training plans. You can chat with your running-specific AI coach anytime to modify workouts, ask training questions, or adjust your plan based on how you feel.

What coaching methods does CoachX offer?

CoachX offers three proven coaching philosophies: 1) Daniels Coach - uses the VDOT-based scientific training system with 5 precise pace zones (E/M/T/I/R), ideal for data-driven runners. 2) Hansons Coach - uses cumulative fatigue training with high frequency (6 days/week) and shorter long runs. 3) Pfitzinger Coach - focuses on high-mileage training (55-85 miles/week) with lactate threshold emphasis, suited for serious runners.

Is CoachX free to use?

Yes, CoachX offers a free plan with 5 AI messages per day and basic coaching features. Paid plans start at $4.99/month for 50 messages/day (Standard) and $9.99/month for 200 messages/day with advanced coaching and priority support (Pro). Yearly billing saves 20%.

Can CoachX create interval workouts automatically?

Yes! Simply tell your AI coach what you need in natural language, like 'Schedule a 30-min tempo run for tomorrow' or 'Create a 5x1000m interval session'. The AI creates the structured workout with correct paces and automatically syncs it to your sports watch via Intervals.icu.

How is CoachX different from my watch's built-in training plans?

Unlike one-size-fits-all watch plans, CoachX creates truly personalized training plans by analyzing your actual fitness data (HRV, heart rate zones, sleep quality, training load). The AI adapts your plan in real-time — if you're tired or injured, just tell your coach and workouts are adjusted instantly. Watch plans can't do this.
