Get Active Together!

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 to raise funds for cutting-edge research and care at Children’s Hospital of Philadelphia (CHOP).

Donations support the Children’s Fund, a flexible funding resource at CHOP that fuels breakthrough care in the communities we serve. You can also choose to support any program at CHOP that you’re passionate about.

How it Works

Register, decide how you’ll get active, and how far you’ll go to help our kids during May.

“When my newborn was emergency transported to CHOP, it was the scariest time of my life, yet I somehow I found comfort in being there. I knew they would find what was wrong with my little boy. I am hoping I can give back a fraction of what they gave us.”

— Brett Keeble,
31-Day Challenge participant and father of Michael
