Challenge Yourself!

Help kids at CHOP by getting active in May

Join us for the 31-Day Challenge, a virtual event in which participants challenge themselves to walk, run or bike 31, 62 or 100 miles during the month of May while raising funds for cutting-edge research and care at Children’s Hospital of Philadelphia (CHOP).

Funds raised through the 31-Day Challenge support the Children's Fund (greatest need of the hospital). Teams or individual participants who raise $1,000 or more can choose any CHOP program to support. If you register as a team member, your funds will be automatically designated to the fund of your team captain's choice.
