- “Find a spring marathon in Ohio or Michigan that's a Boston qualifier.”
- “Is registration open for the Chicago Marathon next year?”
- “Where are the official results for this year's Philadelphia Marathon?”

Common questions
Which running apps officially connect to ChatGPT or Claude?
COROS connects to both ChatGPT and Claude. Strava connects to Claude and Gemini but not ChatGPT. Garmin has no official connector. Marathon Scout's race-data connector works with any assistant that supports MCP.
What is an MCP connector?
MCP (Model Context Protocol) is an open standard many AI assistants, including Claude and ChatGPT, use to connect to outside apps. A connector lets the assistant look things up in that app while it answers you, instead of guessing.
Can an AI assistant find me a marathon?
Yes, with Marathon Scout connected. It can search 2,000+ marathons, halves and ultras by place, month, distance and Boston-qualifier status, and read each race's checked date, registration status and official links.
