Your AI coach adjusts your marathon plan weekly based on how your body is actually responding - not a static 16-week spreadsheet that ignores bad sleep, missed runs, and life happening.
Your weekly volume adjusts based on training load, recovery scores from WHOOP or Oura, and how your body responded to recent long runs. If you bounced back fast from a 20-miler, the next one might be a little longer. If it wrecked you, the plan dials back.
Using your GPS pace data, heart rate drift during long runs, and elevation profiles from Strava, the AI calculates a realistic marathon pace. This updates weekly as your fitness changes.
The AI watches how your body responds to reduced volume during the taper by tracking HRV, resting heart rate, and performance in key workouts. Some people need a 3-week taper, others need 2. Your data determines the right approach.
The AI tracks caloric expenditure, body composition changes via Withings, and sleep data. If your weight is dropping too fast during a training block, it flags potential under-fueling before it becomes a performance problem.
It takes your run data from Strava, recovery metrics from WHOOP or Oura, and body composition from Withings to build a plan tailored to your fitness and goal time. It adjusts weekly mileage, workout intensity, and rest days based on how your body actually responds to training.
Pace, distance, cadence, heart rate zones, and elevation from your runs. HRV, resting heart rate, sleep quality, and strain from your wearable. Body weight from Withings if connected. All of this feeds into mileage decisions and pacing targets.
Most runners see improved pacing consistency and lower heart rates at the same pace within 4-6 weeks. The AI needs about 2-3 weeks of data to calibrate your plan.
Yes. Set your BQ time as the goal and the AI builds a plan around it. It tracks your projected finish time weekly and adjusts training if you're ahead or behind schedule.
Yes - Strava is the primary data source. Every run syncs automatically with GPS data, heart rate, splits, and elevation. Historical data imports on connection.
