Show HN: Transition – AI Triathlon Coach

Hey HN, I’m Alex, a triathlete, dad, and software engineer.

I’ve been building Transition — an app for triathletes that creates adaptive training plans based on your goals, schedule, and workout data (Garmin, Strava, etc).

Most plans are static, which never really worked for me as a parent and someone with an unpredictable schedule. Transition adjusts every week using your actual workouts and progress, so the plan changes when you miss a session, set a new PR, or need to shift your priorities.

I built this because nothing else was flexible enough for my life, and I’m curious if others have the same problem.

It’s in beta and free to try. I’d love feedback from the HN crowd — especially around the training logic, onboarding, or any ways to make it more useful for real athletes.
