- Weekly mileage adjusts based on your recovery metrics and training load trends. A bad recovery week means the plan backs off automatically.
- Race-day pacing comes from your actual workout data and heart rate trends, not a generic pace calculator.
- A 2015 study in the Journal of Sports Science and Medicine found that individualized training plans reduced injury rates by 23% compared to fixed programs.
- The AI monitors cardiac drift during long runs. Increasing drift at the same pace means your aerobic system isn't handling the distance - and the plan adjusts.
AI Marathon Training Coach
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.
What you get
Adaptive mileage planning
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.
Race pace prediction
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.
Taper optimization
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.
Fueling and recovery insights
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.
Questions
How does AI help with marathon training?+
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.
What data does it track?+
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.
How long until I see improvement?+
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.
Can it help me qualify for Boston?+
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.
Does it work with Strava?+
Yes - Strava is the primary data source. Every run syncs automatically with GPS data, heart rate, splits, and elevation. Historical data imports on connection.
