IcuSync: Claude for Your Training Calendar
IcuSync connects Claude AI to Intervals.icu so athletes can question training data, generate structured workouts, and send sessions to connected devices.
Field notes
IcuSync uses Intervals.icu as the training-data and calendar layer, with Claude acting as the conversational interface. The setup connects the athlete’s Intervals.icu account through OAuth and adds the service to Claude via an MCP URL or desktop extension. The page lists eighteen Claude tools, including fitness, fatigue, form, power-curve, training-zone, best-effort, and calendar functions. A separate Notion template supplies a training log, weekly review, plan builder, and prompt reference.
