The state of AI in cycling training
In short Most AI in cycling training today does one of two things. Either a training platform's own model picks your next workout and adjusts your FTP, or a general chatbot reads your ride history and talks to you about it. TrainerRoad rebuilt its engine around in-house models in January 2026. Strava gave Claude read-only access to subscribers' files in June. Zwift now pushes workouts from third-party AI coaches straight into the game. Garmin, Strava and TrainingPeaks' new owner are tightening who can reach your data and on what terms. The evidence has not kept pace. The vendor figures are unaudited. The published studies of LLM-written plans cover strength training, running and clinical exercise, not power-based cycling, and they rate the plans as moderate at best. For now, testing these tools against your own ride files is still the only check you can trust.
What it found
- The main platforms now sell AI as part of the subscription, not as an add-on: TrainerRoad bundles its AI at no extra charge, and Strava's Claude connector and Garmin's Active Intelligence are paid-tier perks.
- Access to your ride data is consolidating. Strava bought Runna and The Breakaway, Garmin bought TrainingPeaks, and Strava now charges developers for API access and has dropped intermediary platforms.
- General-purpose LLMs now have official routes to training data, but read-only: Strava's MCP connector cannot write workouts, and ChatGPT Health launched without Strava and excluded the UK.
- No published peer-reviewed study has tested LLM-generated plans for power-based cycling. The nearest work, on strength and clinical exercise, finds moderate quality and inconsistent intensity prescription.
- Vendor accuracy claims are unaudited: TrainerRoad's 33% lower failure rate and its 27% claim come from its own forum posts, with no published method or sample sizes.
- In the WorldTour, AI is now used for pacing and nutrition modelling, but the published accuracy is modest: Visma's nutrition predictions are reported at 52% to 82%.
How it was made
Every development in the report comes from a public source dated from April 2025 to August 2026: trade press, regulators, journals and company announcements. Each one is dated and names its source, so you can read the original, and every link was checked when this edition was put together. It is a record of what happened, not advice.
A new edition replaces this one as things move. The latest is always on this page.
