Get ready to strip down for a cause at Cupid's Undie Run - Detroit, a vibrant and unique one-mile(ish) dash happening on February 14, 2026, in the heart of Detroit, MI. This isn't just a race; it's a "pantless party with a purpose," where thousands gather across the U.S. to raise vital awareness and funds for Neurofibromatosis (NF), a group of genetic conditions causing tumors to grow on nerves throughout the body. Detroit's leg of this nationwide event kicks off at Tin Roof Detroit, located at 47 E Adams Ave St., setting the stage for an unforgettable afternoon of fun.

The festivities begin with a lively pre-party, featuring drinking and dancing to get participants energized and ready to brave the brisk Michigan air. Typical race day conditions in mid-February see highs around 33F and lows around 20F, with a minimal 6% chance of precipitation, making the "chilly cheeks" part of the unique experience. Around 2 PM, runners will jog out for a mile-long route that has historically taken participants around Comerica Park, offering an urban backdrop to this spirited event. While specific elevation details are not provided, the urban course is generally flat, making it accessible for all levels of runners and walkers.

What truly sets Cupid's Undie Run apart is its commitment to charity combined with an incredibly fun and inclusive atmosphere. Participants, who must be 21+, don their finest (or funniest) underwear and costumes, running in solidarity for those affected by NF, who cannot hide their tumors. The event culminates in an epic dance party at Tin Roof Detroit, celebrating fundraising achievements and the collective effort to find a cure for NF. It's a chance to be part of a meaningful movement while enjoying "the most ridiculous 'mile(ish)' of your life".
