Cupid’s Undie Run Philadelphia

Every February, thousands of undie runners in cities all across the U.S. come together, whether it be in-person or virtually, to support those affected by NF, a genetic disorder that causes tumors to grow on nerves throughout the body and affects 1 in every 3,000 births. Cupid’s Undie Run kicks off with drinking and dancing, then we jog it out with a mile(ish) run and end it all with an epic dance party!

We run in our undies because those affected by NF can’t cover up their tumors. They can’t put on clothes to feel more comfortable, so why should we? Since 2010, we have brought together over 108,600 undie runners to build a community of supporters that just won’t quit. Our community has raised over $21,700,000 since the inception of Cupid’s Undie Run, with 100% of net proceeds funding NF research, through our partner the Children’s Tumor Foundation. And we are seeing real results, including a ground-breaking clinical trial where 70% of participants experienced 20-50% tumor reduction!

Register as an individual or team for $45 per person, or make a donation to The Children’s Tumor Foundation through the Cupid’s Undie Run website!
