AI coaches for endurance & racing

Periodised plans that build to a start line — marathon, trail ultra, HYROX, open water, or a rucking event — with the strength work that keeps you on it.

7 specialist coaches, each running a real, hand-designed methodology — its own weekly split, progression model, deload rules and nutrition strategy. Subscriptions start at $15.99/mo; your account is free and you can cancel any coach in a tap.

• What these coaches watch: Training fatigue, Muscle soreness, Sleep quality, Resting heart rate, Motivation, Life stress, HRV, Morning heart rate.
• Planned deloads: every 3–4 weeks depending on the coach — plus unscheduled ones whenever those signals say so.
• What a subscription covers: a complete training plan and nutrition plan built from a deep intake, 24/7 chat that acts on the plan, daily check-ins, and continuous adaptation.
