About the project

Built by a triathlete, for triathletes

TRI-HARDER started as a personal project to see what would happen if you gave an AI access to your actual training data. Instead of generic advice, you get a coach that knows your workouts, your goals, and your fitness history. It's free to use and your data stays private — no third-party analytics, no selling your information.

— Martin Chan, creator of TRI-HARDER
