Introducing Train Ultra: a private coach that reads every workout

Most of us train hard, and most of us train alone. We follow a plan we found or pieced together, we upload to Strava, we squint at the numbers, and then we guess. Was that the right session? Am I recovered enough to go again tomorrow? Is any of this actually working? We have more data than any generation of athletes before us, and almost none of the thing that data is supposed to buy: someone who is paying attention.

I know that gap well. I once paid real money for a coach, and the part that stung was never the price. It was that the person on the other end never really co-invested in me. Not the time, not the energy, not the care. I would send a hard week into the void and get back a thumbs up, if I got anything at all. So I stopped paying, and I started building the coach I actually wanted.

What Train Ultra is

Train Ultra is a private AI coach for endurance athletes who use Strava. The moment you finish an activity, it reads the whole thing. Your pacing, your effort, how the heart rate behaved, how it sits against your recent training and your recovery. Then it tells you what it sees, in plain language, the way a good coach would.

It remembers. It knows what you are training for, it knows the last two weeks you put in, and it carries your past conversations forward. So when you ask "should I still do my long run tomorrow," it does not give you a generic answer. It looks at your actual readiness, notices your HRV has been under baseline for two days, sees the volume you just stacked, and gives you a real call. Protect the key session, keep tomorrow easy, move the long run to Sunday. That is the difference between a chatbot and a coach: a coach knows you.

The evaluations are the proof

The clearest way to feel that something is actually paying attention is to watch it read your work. Finish a run and within seconds Train Ultra breaks it down: what the session really was, whether your execution matched the intent, what your body was telling you, and what to do next. It can post that read straight to your Strava activity, so the feedback lands where your training already lives.

These are not cheerful one liners. When a recovery shuffle was exactly the right call, it says so and tells you why. When you turned an easy day into sneaky tempo work, it calls that out too. Honesty over flattery. A coach who only ever tells you that you crushed it is not a coach.

And everything around it

The coach gets smarter the more it has to work with. Set a goal race and your progress toward it is woven into every evaluation and every answer. Connect Garmin and it factors your sleep and recovery into what it tells you to do next. Every week it writes you a short, honest summary of where your fitness is actually heading. Bring in a plan and it knows what you were supposed to do, and how it went. There is a native iOS app so all of it rides in your pocket.

And yes, it rewrites your Strava titles into something that actually describes the run instead of "Morning Run." That was the very first thing Train Ultra ever did, and people still love it. It is the smallest thing here, and a quiet delight. It is just not the point. The point is the coach.

What it is not

Train Ultra does not replace your judgment, and it does not pretend to be a doctor. It is not a place to dump your data and forget about it. It works best the way a real coaching relationship works: you train, it watches closely, you talk it through, and over weeks it gets to know you. Your data stays yours. I read only what is needed to coach you, I never sell it, and I never use it to train AI models. You can disconnect or delete in a tap.

Start free

You can start today for free. Connect Strava, finish your next workout, and read what your coach has to say about it. If it earns a place in your training, there is a Pro tier that unlocks the full conversation. If it does not, you lose nothing.

I built this for people like me, who care a lot about doing the work right and have never quite had someone in their corner who was paying attention. If that is you, I would love for you to give it a run.
