Yellowstone Half Marathon

  • Yellowstone Half Marathon Start My Journey

This is not just any race – we're in a race to save our one and only planet. Join Team Sierra at the 2020 Yellowstone Half Marathon on June 13 to do what you love while helping to ensure a livable home for us and future generations.

Stronger and more frequent natural disasters. A lack of clean air and safe drinking water in our most vulnerable communities. Various reports outlining irreversible damage to our planet. It's clear that the climate crisis is not just one of the greatest threats we face. It's already here: People around the country and world are being impacted by our warming planet every day.

We also know we can do something about it. Tackling this global threat will take ambitious goals and plans – and luckily, we know that Team Sierra teammates thrive on big goals and hard, meaningful work.

Entries are limited and are first-come first-served to those who commit to raising $1,000 for Sierra Club.
So join Team Sierra in Yellowstone and cross the finish line knowing you made a real impact raising critical funds to protect our planet.
