A TrainerRoad 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 Strava or intervals.icu in Blocks and your ride history comes in, the rides you did in TrainerRoad included. Tell the assistant your goal, your race and the days you can ride, and it drafts the plan for you to approve. Sessions go to Wahoo and Karoo, to Garmin through intervals.icu, or download for Zwift — and any of them still exports as an .erg or .mrc file if you want to keep riding them in TrainerRoad.
