Team Challenge is the Crohn’s & Colitis Foundation’s endurance program, created to raise funds to accelerate the progress of breakthrough inflammatory bowel disease (IBD) research, education, and support for those suffering from IBD.

You can walk, run, or move any way you like in support of the IBD community — while getting us one step closer to IBD cures.

When you join Team Challenge, you’re supported by coaches and teammates who understand the impact of IBD. We’re a community united to help find cures for millions of Americans living with IBD.
