Registration is open for our 2026 events! 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!
We're on a mission to raise awareness and fund critical NF research while running in our undies!
With your help, we can help improve treatments, care, and lives for those living with NF.
