UNBOUND Gravel
CKF Bike Team
UNBOUND is a 4-day biking event in Flint Hills, Kansas, and is considered the world’s premier gravel event. As a lottery event, these race spots are extremely coveted. Racers agree to fundraise and raise awareness for the Foundation, and in return become a member of Team CKF! The CKF Gravel teams allow us to reach over 16,000 individuals and introduce them to organ, eye, and tissue donation.
2025 was a huge year of growth for our Unbound Gravel Team. This was just the second year we had participated in the race. Team CKF saw 16 riders take up the challenge, and 14 made it over the line. Our riders and their supporters helped raise over $50,000 to help us educate, inspire, and register.

Thank you to our 2025 Sponsors!

Jess Tucker
Jess has always believed in helping others and therefore the answer to “Will you be an organ donor?” was always yes.
She is a passionate volunteer in her community, and loves to donate her time and funds to great causes. Jess feels organ donation is the ultimate way to donate, and help someone live a full and meaningful life. She encourages others to consider registering.
Jess loves adventure, and there is hardly anything she will not turn her hand to. She started with running long distances, but has since taken up gravel riding and mountain biking. She always races in honor of her mom, Christine, who passed away from Multiple Myeloma at just 54.
Jess will ride Unbound this year for her mom and her lasting message that life is way too short not to go for it all!

Trevor Stern
Trevor has been a registered donor since the age of 16 when he got his driver’s license. He remembers not fully understanding the question, but knew the impact he would have on someone else’s life.
He raced the Leadville 100 TR through a charity, and was inspired to continue racing and riding for a cause as it made the experience even better.
Trevor is an ultra-runner turned gravel biker. He has always wanted to tackle the Unbound 200, and this will be his first true challenge on a bike.

Chris Klug
In 2003, Chris used $3,000 out of his own pocket to start the Chris Klug Foundation.
Chris was a professional snowboard racer when he was placed on the National Transplant Waiting List after being diagnosed with Primary Sclerosing Cholangitis (PSC), a rare degenerative bile duct condition. He spent six years on the waitlist, critical for the last three.On July 28, 2000, Chris received his liver transplant, and said, “It was like a new engine was dropped in me!” Six weeks later, he was back on his snowboard, and had the opportunity to represent the USA at the Winter Olympics in Salt Lake City, Utah, where he won a bronze medal.
During Chris’s time on the waiting list, he promised himself he would do everything he could to spread the message of organ, eye, and tissue donation once he was able.
This will be Chris’ first Unbound.
