Which running coach apps actually sync with Strava?

What 'syncs with Strava' actually means

Strava's API offers apps three very different levels of integration. Direction: reading your completed activities, pushing planned workouts, or both. Freshness: apps that register webhooks are notified within seconds of you saving a run; apps that poll only update when you open them. Depth: some apps read just distance and time, others pull the full streams — heart rate, pace, cadence, elevation profile — which is what load tracking and adaptive coaching actually require. When you evaluate a coaching app, ask which of the three it does; the marketing word 'sync' hides the difference.

Why it matters for coaching

A coach that cannot read your history has to ask you questions you should never have to answer: what is your weekly volume, what pace was your last long run, how did the week actually go. A coach that reads summaries but not streams cannot see that your heart rate is drifting up at the same pace — an early fatigue signal. And a coach that syncs only when you open the app coaches yesterday's runner. Reading depth and freshness are not technical trivia; they are the difference between advice based on what you said and coaching based on what you did.

The honest landscape

Runna (acquired by Strava in 2025) reads activities and pushes workouts to watches. TrainingPeaks syncs completed activities and is built around coach-athlete analysis. Nike Run Club records with its own tracker and can share runs to Strava, but does not coach from your Strava history. Garmin Coach adapts plans from data inside the Garmin ecosystem. ChatGPT and Claude, on their own, have no Strava connection at all. Coach Leo reads your full activity streams in real time via webhooks (read-only — it never modifies your Strava), also takes Suunto and Polar as direct sources, imports history from Apple Health and Health Connect, and pushes planned sessions to Suunto watches. Each of these designs serves its product; the question is which one serves a coach that adapts to you.

The new option: your data inside ChatGPT and Claude

Since 2025, assistants can connect to external tools through MCP (Model Context Protocol). Coach Leo ships an MCP server (setup instructions): connect it once and ChatGPT or Claude gains real coaching tools backed by your synced history — your last runs, your load, your plan, your race calendar. You keep the assistant you already use; it stops guessing and starts reading. Any signed-in Coach Leo account can connect, including free ones.
