CONNECTED TO STRAVA · IOS & ANDROID

A coach
that kicks
your ass. For real.

Not an app that congratulates you for getting out of bed. A coach that read your Strava run, remembers the last one, and isn't afraid to tell you that you blew it.

OK. Let's be honest.

You ran 9 km at 5'02 and then blew up. The last three at 5'35 — that's not a run, that's a confession.

Same pattern last week. Like you just discovered runs last more than 30 minutes.

Wednesday: 4×1 km, negative split. You finish faster than you start. Non-negotiable.

WHAT THEY'LL TELL YOU

No more
'great workout' praise.

The messages below are the kind of thing you'll get. Not generic feedback. Specific calls. Dated. Signed. You'll hate them at first. You'll wait for them by the tenth.

« Your interval session looks like a grocery list. You did whatever you felt like in whatever order. That's not training, that's a brunch. »
