  The Chris Klug Foundation is proud to be a charity partner for the 2026 Cape Town Marathon as it bids to become an Abbott World Major Marathon.

  This year, five individuals will have the opportunity to raise awareness and funds for our mission to eliminate the wait for a transplant. We work across the United States, educating and inspiring individuals to register as organ, eye, and tissue donors. Alongside this, we work to show the world what is made possible due to the gift of life through giving recipients, donors, and supporters a platform to make the impossible possible post-transplant.

  The foundation was started in 2003 by an Olympic Bronze Medalist after a liver transplant saved his life. Chris received his transplant in 2000 thanks to the courageous decision made by the donor and their family. Two years later, Chris honored them by becoming the first and only solid organ transplant recipient to not only compete at the Olympics but also win a medal in snowboarding. His donor family presented his medal to him on the podium. Just one year later, Chris founded CKF with $3,000 from his own pocket and set its life mission to INSPIRE, EDUCATE & REGISTER!

  If you are interested in joining the team and running for a lifesaving mission, apply today, or support our runners as they chase their dreams with a purpose.

  The Grin & Bear It is Crested Butte’s oldest trail challenge. Historically presented as a sprint to Green Lake and back, this classic event has evolved to offer a 25k Loop competition while still maintaining the traditional 15k race.

  New in 2025, the Grin and Bear it BIKE! This route will follow the 25k run route, excluding the .7 miles to Green Lake and back. This challenging route is roughly 14.83 miles with just under 4k feet of climbing.

  Note- there is minimal swag and no podium awards for this event.
