Blocks vs TrainerRoad

Choose Blocks if you want an assistant that reads your real data and cites its sources, or you already live in Claude and want it to see your training — without another monthly subscription. Choose TrainerRoad if you ride indoors a lot and want a proven adaptive cycling plan inside one app.

Can you use both?

Yes. Any Blocks workout exports as an .erg or .mrc file for TrainerRoad, and your TrainerRoad rides reach Blocks through Strava — so you can plan and review in Blocks and ride the session in TrainerRoad.
