Runners often have more data than they know what to do with. With sleep scores, HRV, training load, recovery status and more—it can be challenging to figure out what information is important and how to use it.
Coros is trying to make that easier by helping athletes connect their data with AI platforms, including ChatGPT and Claude. The wearable company has launched a new tool called an MCP (model context protocol) that lets athletes connect their Coros training data to AI platforms, then ask questions about their training in plain language. The answers are based on their own workout and recovery data, not generic training advice.

Data made easy
The first version is read-only, so it can analyze data, but can’t change anything in an athlete’s account. North American and European users can connect the tool with ChatGPT Plus and Claude Pro at launch.
Once connected, athletes can ask about multi-week training load, pace trends, heart rate, recovery, sleep, HRV and race readiness. They can also use it to build custom reports, dashboards or spreadsheets without having to export files or write code.

Why AI?
Coros says that requests for access to its data have jumped sharply over the past year, with API integration requests rising by more than 1,100 per cent. (API integration is essentially a way for one app or platform to connect with another and exchange data.) Instead of relying only on traditional third-party integrations, the company is giving athletes a more direct way to work with their own data.
Coros CEO Lewis Wu said the goal is to keep athletes in control of their information. “We’ve always believed that athletes should have complete control of their data and retain the ability to work with it however they choose,” Wu said. “With the new MCP, those choices can now include asking large language models (LLMs) for training advice, and feeling confident that answers will be based on their actual training data, not generic recommendations.”

Privacy and control
Coros says that athletes authorize the connection through their existing Coros login and can revoke access at any time. The company also says payment information, passwords and data outside the Coros training ecosystem are not accessible through the MCP. The data is still processed through whichever AI platform the athlete chooses, so that platform’s privacy policy also applies.
What comes next
For now, athletes can ask questions and generate analysis, but they can’t use the tool to write workouts back into their Coros calendar. That may change. Coros says it is working on future write permissions, which could allow AI-generated training plans, automatic workout scheduling and plan adjustments based on race goals and recovery.
