Ten years ago, Cupid’s Undie Run was a single silly event designed to raise money for charity, held in Washington, D.C. Today, the premise is still the same—runners strip down for a fun run to raise money for the Children’s Tumor Foundation—but it has exploded in popularity. More than 40 cities host their own rendition of the annual event. Get in on the fun where it all started at the Cupid’s Undie Run 2020 right here in D.C.

It’s slated for Saturday, February 8th from noon to 4 p.m., beginning and ending at Penn Social. Sign up to run a mile for a good cause and come dressed in your Valentine’s Day-themed undies or a fun and festive costume. Registration costs $40, most of which goes to the Children’s Tumor Foundation. After the run, feel free to hang out at Penn Social and grab a few drinks with your fellow scantily clad runners before heading back to your apartment near Seward Square DC.
