Every February, thousands of runners across the U.S. strip down to their undies to hit the streets—all in the name of finding a cure for NF (neurofibromatosis).
Cupid’s Undie Run kicks off with drinking and dancing at Tin Roof, then a mile(ish) jog/run and ends with a dance party back at Tin Roof. The 2026 Detroit event will take place on Sat., Feb. 14 from 12 – 4 p.m. (run starts at 2 p.m.).
When: Sat., Feb. 14, 2026
Where: Tin Roof, 47 East Adams Ave., Detroit
