Strava, COROS and Garmin in ChatGPT and Claude: Which Running Apps Actually Connect

Until this spring, most ways to get your training into an AI assistant came from third parties. Now COROS and Strava have official connectors, and they don't work with the same assistants.

COROS: ChatGPT and Claude, and it can write

COROS went first, in May. Its connector is now listed in both the ChatGPT and Claude directories. According to COROS's official repository, it reads activities, laps and FIT files, sleep, HRV, stress and recovery status, plus COROS's own race predictions and training load. COROS doesn't charge for it.

It has also grown past reading. The same repository says it can create and change training plans and workouts and put them on your COROS calendar. Ask for next week's sessions around a 16 mile long run and they land on your COROS calendar. Plans must run 4 to 16 weeks, and it can't delete a plan or workout. Anything you ask it to save is written to your account, so read a plan before you accept it.

Strava: Claude and Gemini, subscribers only

Strava's connector arrived in June for Claude, and Gemini followed in October for US accounts. Strava's help page lists what it can read: activity history, fitness trends, best efforts, gear, streaks and activity weather. It's read-only, and it needs a Strava subscription.

There's no official ChatGPT connector. Third-party tools that link the two exist, but Strava doesn't make or support them.

Garmin: nothing official

Garmin hasn't shipped a connector for any assistant. What it did ship, in October, is a free Personal API key for your own data, and a crop of hosted services and open-source servers is building on it. Some of those tools still ask for your Garmin password instead of sending you to Garmin's sign-in page. Skip those.

Adding the race

Training data answers "how fit am I?" It doesn't answer "where should I race?", and race dates and registration windows change every year, after most assistants' training data was collected.

Marathon Scout now has its own free connector for that half of the question. It searches 2,000+ marathons, halves and ultras by place, month, distance and Boston-qualifier status, and returns each race's checked date, its registration status with the date we last checked it, and links to the official results and live tracking. It works in Claude, ChatGPT, Cursor and any other app that supports MCP, with no sign-in.

With Strava or COROS connected alongside it, a question like "look at my last 12 weeks and find a spring marathon in Ohio or Michigan that suits that training" can be answered from your real mileage and a real race calendar instead of the assistant's memory. Setup is one URL.
