2026 Cupid's Undie Run Washington D.C.

Brave the Cold, Warm the Heart: America’s Biggest Pants-Free Party for a Cure is Back!

In February, thousands of bold, pants-less participants will hit the streets in 34 cities across the U.S. for the annual Cupid’s Undie Run, a one-of-a-kind fundraiser for the Children’s Tumor Foundation (CTF). This unforgettable event raises awareness for NF and funds vital research to combat the rare genetic condition that causes tumors to grow all over the body.

Fearless fundraisers in eye-catching outfits - everything from superhero undies to laugh-out-loud costumes - will join in America’s most daring and fun-loving charity event. The day kicks off with music, mingling, and a drink (or two), followed by a "brief" one-mile(ish) jog and an epic dance party to top it all off, celebrating the best costumes and top fundraisers.

And we need YOU to help pull off this pantless party in Washington, D.C! Join our tribe of undie-loving "thrillanthropists" on February 21st, 2026. Express interest here or each out to DC@Cupids.org to get in touch and receive more information on what volunteer opportunities are available.
