I built Kresta for my wife and friends, so we could train better and get a bit faster together. The idea: proper, science-backed fitness tracking that's actually simple, with an AI coach that gets both your cycling and your running.

Didn't sleep well? Just tell the coach. Heading off for the weekend, or knee-deep in a house project and can't train? Tell it, and it'll shuffle your plan around for you. Gym too. Swimming? Wish I could. :-)

I'm a cyclist from Stockholm. Raced road, cross, MTB and TT back in the day, mostly gravel now, like everyone else. Not racing these days, life's full with a job and three kids, but I'm still trying to squeeze the best out of the time I've got.
