Coach AI ✓

Coach AI is an endurance coach you talk to, running on the data your Garmin or Apple Watch already collects. Instead of a fixed plan, it builds a periodized season around your races, reads your training every day, and adjusts the week when sleep, HRV, stress, weather or an injury change the picture. Ask why a workout matters, tell it you are exhausted, and get an answer specific to you.

What it does:
- Season planning: name your races and Coach builds base, build, peak and taper phases on your calendar. Change a goal and it replans.
- Adaptive weeks: a sick day, a work trip or bad weather reshapes the week across running, cycling, swimming and strength.
- Injury-safe comebacks: tell Coach about an injury or health condition and it rebuilds the plan around it with safe alternatives, gradual load progression and a readiness-guided return.
- Workout analysis: every session reviewed for pace, heart-rate zones, cadence, power and splits.
- Send-to-watch: build a structured workout in chat and sync it straight to your Garmin.
- Beyond training: fueling and nutrition guidance, recovery insights, bloodwork analysis, personalized HR zones.
- Memory: say "long runs on Sundays, no treadmill" once and it shapes every future plan.

How it works: a large language model grounded in sports-science rules and your real training history. Training load (CTL, ATL, TSB), HRV, sleep and readiness come straight from your device, not from a questionnaire. Coach explains the reasoning behind every recommendation, so you learn as you train.

Who it is for: runners, cyclists, triathletes and multi-sport athletes from a first 10K to Ironman, HYROX and ultras. Especially useful for masters athletes and anyone training around an injury, illness or health condition, where rigid plans fail.

Pricing: free 7-day trial, no credit card. Coach Pro is $19.99 per month or $119.99 per year. Available on web and iOS.
