OpenPacemaker · coach Alex · first half marathon

Morning Alex. First half marathon, exciting. Ask me anything, or tap a question below.

Your first race

I've run a few 5Ks but never further. I'd love to do a half marathon in the spring. Is that mad?

Not mad at all. That's about 16 weeks away, which is plenty. We'll start where you are: three runs a week, almost all easy, with one that slowly gets longer.

I'll set the first week up now, and you can change anything you don't like. Want to pick a date together?

Coming back carefully

Right Achilles is a bit tight after this morning. Maybe 3 out of 10.

Logged. You had this back in March and one easy week settled it. Let's do the same: I'll keep this week easy and swap Tuesday's intervals for a steady run.

Tell me how it feels tomorrow and we'll take it from there.

When life gets in the way

Brutal week at work, haven't run since Tuesday. Can I just bin the long run tomorrow?

Yes. Tomorrow becomes 30 minutes easy, and I'll move the long run to Saturday. You lose a little volume but the session that matters stays in. Don't sweat the missed days.

Chasing a PB

Tempo this morning felt awful. Legs were heavy from the start, went out too fast I think.

8.4 km at 4:19/km, average HR 178, and a clear positive split: 4:02 early, fading to 4:38 by the end.

You're not losing fitness. You stacked two hard days too close together, so you spent it twice. Easy tomorrow, and I mean properly easy.

More than one sport

Logged a long ride and a swim this week too, not just the runs.

Seen both, nice mix. That ride added real aerobic load on top of your running, so I've kept tomorrow's run genuinely easy rather than stacking another hard day on tired legs.

you don't have to ask

Most tools wait for you to open them. OpenPacemaker reaches out first: a short read in the morning, a word after a hard session, a weekly review you never had to request. It holds your plan and rewrites it as your week actually goes.

It also learns how you like to be coached. Some athletes want it blunt, some want a gentler hand, and it adapts. And it puts safety first: if something looks risky, a niggle that's escalating or fatigue that's gone too deep, it tells you, even on a quiet day.

It actually remembers you

what do you actually know about me?

Quite a lot by now: your goal of a sub-1:45 half, the right-Achilles history, that you prefer hard sessions on Tuesdays, and that work travel usually eats your Wednesdays.

Want the full picture? Type /aboutme and you can read everything I hold, and correct anything I've got wrong.

but can't I just ask an AI about my Strava now?

You can, and it's genuinely useful. Strava added a Claude connector: plug in, ask a question, get an answer from your own data. If all you want is the occasional "were my easy runs easy enough?", that's a fine tool.

But that's a search box for your history, not a coach. It waits for you to ask, forgets you between chats, holds no plan, and only ever sees Strava.

OpenPacemaker is the other thing. It watches every session and reaches out first, holds a plan and rewrites it as your week goes, remembers you across months, reads your Garmin recovery, pushes structured workouts to your watch, and coaches across run, ride, tri, swim and hike.

Ask an AI and it tells you what happened, when you ask. A coach tells you what to do tomorrow, before you do, towards a goal.

a note on Telegram

The coach lives in Telegram because its Bot API is free, which is a big part of how OpenPacemaker stays free for you. It's the same kind of chat you already know: messages, voice notes, replies. A 30-second install on iOS, Android or desktop, and the coach is just one more conversation in your list.

How it stacks up

Other tools log your activities, build a plan, or answer a question when you ask. None of them coach you: proactively, with memory, towards a goal.

Public features, June 2026. Strava, intervals.icu, TrainingPeaks and Runna are excellent in their categories. OpenPacemaker is for the athlete whose problem is "I want a coach who knows me", not "I want somewhere to log my runs".

You can keep screenshotting your Strava into a chatbot every Sunday. Or your coach can read your data, message you first, reshape your plan and remember you, every day, from inside a chat you already have open.
