High-performance triathlon, swim & bike coaching for ambitious women and driven athletes who are done playing small.
Train smart. Race hard. Heal through movement. Based at 1,800m in the Swiss Alps.
I'm Elisabeth Lahtinen — Lizzie — coach, Ironman finisher, and someone who knows what it's like to push your body to the limit and still feel like it's fighting you.
I've had my own battles with body image, overtraining, and feeling unseen by coaches who just didn't get it. That's exactly why I coach the way I do: with data, discipline, and deep respect for what your body is telling you.
Based in St. Moritz, I work with finance professionals, driven women, and ambitious athletes who are done with mediocre. Ironman prep. Swim & bike coaching. Nutrition guidance. All built around you.
Every offer is designed to meet you where you are — and push you way further than you thought possible.
Full Ironman prep for type-A athletes who want to actually race, not just finish. Structured, periodized, brutally honest — just like you asked for.
Premium · Private 1:1Training designed around YOUR body — hormones, cycles, load, recovery. For determined women tired of coaches who don't get it. You deserve better.

It's been through so much. And it's still showing up for you. Let's train it with the respect it deserves — and push it further than you ever imagined.
Let's Talk, Babe ✦Lizzie doesn't just coach you — she sees you. For the first time I had a coach who understood what training around my cycle actually meant. Game changer.
I came to St. Moritz for work and left with a swim technique and a new obsession with open water. Lizzie is the real deal — no fluff, all fire.
She believed in me before I believed in myself. I crossed that finish line in tears. Lizzie will push you harder than you ever pushed yourself — with so much heart.

Your body, your call — I'm here to support, not replace professional medical advice.
