Andie Cornish Signs with Mammut

Send us Fan Mail

A lot of athletes say they love the mountains, but Andy Cornish actually builds her whole season around them. We talk about Jackson Hole summer life, getting up on the Grand Teton, and how growing up in the Tetons shaped a style that blends trail running, mountaineering, and ski mountaineering into one “mountain athlete” path.

Andy also shares what it feels like to join the Mammoot team and why the fit matters when your goals don’t look like the standard trail racing checklist. We get into the gear details that make big days smoother, including a vest-style 15-liter pack that can carry water up front and still haul climbing essentials, plus what she looks for in traction and support when moving fast on technical terrain.

Then we go deeper on the question I’ve started asking more often: what’s your why? Andy breaks down the mix of nerves, excitement, peace, and empowerment that comes from choosing hard objectives, especially as a woman in a space that still needs more representation. We close with a practical note every runner understands: foot care, injury mitigation, and why insoles and socks can make or break consistency when plantar or peroneal issues flare up.
