I’m Christina, a mental coach and ultrarunner.

I spent years building products at Red Bull and adidas, and I learned the same thing in both worlds: the body and the strategy aren’t usually what give out first. The mind is. This is where I think out loud about that, somewhere between kilometer 80 and the next big decision.

I write for two kinds of people, and often they are the same person: people leading products and teams, and people running long distances. Both carry more weight than anyone sees. Both hit the same wall, the story you tell yourself when it gets hard.

What you’ll get here is raw and deep. No fluff, no life optimization, no funnel. Personal stories first, one solid piece of research as backbone, and something you can actually use. Every other week, quietly, in your inbox.

If this landed with you, the best thing you can do is stay. Subscribe.

And one more thing, I read every reply. So: what’s the wall you’re hitting right now, in training or at work? Hit reply and tell me. I mean it.
