Registration is open for the 2025 event! Every February, thousands of undie runners in cities across the U.S. come together, whether it be in-person or virtually, to support those affected by NF, a group of genetic conditions that cause tumors to grow on nerves throughout the body.  

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! Join the party in Baltimore; purchase a ticket or sponsor a team today!
