Here's how athletes and coaches use ICU Coach every day.
"The Morning Report changed my routine. I check my readiness every morning before deciding on intensity."
"Auto Coach saves me hours of planning. One tap and I have a workout that respects my recovery."
"As a coach, the team dashboard lets me monitor 15 athletes at once. The AI reports save me 2 hours daily."
Subscribe to a Coach plan, create invite links, and build your roster. Athletes authorize via Intervals.icu OAuth — you get instant access to their training data and AI reports.

BYOK means you provide your own AI API key (Google Gemini or OpenAI). This gives you unlimited AI requests at the cost of your own API usage. It's the most cost-effective option for power users.
Cloud AI: No setup needed — we handle everything on our servers. You get 50 requests/day. BYOK: You enter your own Gemini or OpenAI API key and get unlimited requests. BYOK is cheaper long-term; Cloud is easier to set up.
Recovery Pro is our science-based recovery engine. It tracks 3 systems (Metabolic, Neuromuscular, Hormonal) and uses a 21-day rolling percentile gate to determine when you should rest. It can override AI coaching recommendations to protect you from overtraining.
