Private AI coach for endurance athletes
A private coach who reads every workout you log.
Train Ultra reads every activity the moment you finish, remembers your goals and history, and is always there to talk it through. What today meant, what to do next, why it felt the way it did.

The coach
It's a conversation, not a dashboard.
Ask anything, any time. Your coach has read every mile you've logged, knows what you're training for, and pulls your real numbers into the answer. Like texting a coach who never forgets.
-
Remembers everything. Your goals, your history, and past conversations all carry forward.
-
Works from real data. It reaches into your actual splits, paces, and recovery trends before it answers.
-
Always on call. 2pm taper jitters or a 9pm "should I run tomorrow?", it's there.
Workout evaluations
Proof it's actually paying attention.
Seconds after you finish, your coach reads what actually happened. Pacing, effort, recovery, how it fits your plan. Then it can post the read straight to your Strava activity.
This read as recovery, not training, and that was the right call. Heart rate sat well below your easy aerobic range and the splits drifted slower as you went, which says you were protecting tired legs, not chasing a stimulus. With HRV under baseline for a third straight day, that restraint is what this week needed. Tomorrow's easy 6 is already on the calendar. Keep it fully conversational, and if the legs feel flat after 15 minutes, make it a brisk hike. For a 100, absorbing the work beats adding junk miles.
How it works
Keep training the way you already do.
One tap. We read your activities so the coach works from your real training, and we never post anything to Strava without your say-so.
Seconds after you finish, it's analyzed. Pacing, effort, recovery, and how the session fits the bigger plan.
Ask what today meant, what's next, or why it felt hard. It remembers the answer the next time you ask.

And one small delight
Oh, and your activity titles? Handled.
Every activity lands on Strava with a title that actually says what you did, written by the coach that watched it. It's the smallest thing Train Ultra does, and a quiet favorite.
Your data, your call
We read only what we need to coach you.
What the coach writes is yours. Post it back to Strava automatically, keep it private, or choose per activity. We never sell your data or use it to train AI models, and you can disconnect in one tap, any time.
