A TrainingPeaks alternative with an AI assistant

Blocks is an AI-native training platform for cyclists and runners. Built around an assistant that reads your calendar, rides and readiness, plans and adjusts the week, and answers from a sourced sports-science base with evidence levels. It shows every change and asks before writing. It is free to use, and it works inside your own Claude as well as in the app.

How to move across

Connect intervals.icu in Blocks and your training history comes in. A plan you already have in TrainingPeaks can follow: the open-source tp2intervals tool copies it to intervals.icu, and from there it lands on the Blocks calendar. If you work with a coach in TrainingPeaks, nothing forces a choice — keep their plan there and use Blocks to read it.
