Get ready to strip down for a cause at the Cupid's Undie Run - Baltimore, hitting the streets on February 28, 2026! This isn't your average race; it's a "brief" fun-run and a massive party, all dedicated to raising funds and awareness for the Children's Tumor Foundation to combat Neurofibromatosis (NF), a genetic disorder that causes tumors to grow on nerves throughout the body. Participants are encouraged to embrace the spirit by running in their undies, or get creative with costumes, tutus, or even flannel onesies. It’s a chance to be bold and support a critical mission.

The Cupid's Undie Run in Baltimore offers a lively one-mile (ish) course through the city, often kicking off and concluding with an epic dance party at popular local venues like The Admiral's Cup in Fells Point. While specific elevation details aren't highlighted for this urban dash, runners can expect a generally flat or gently rolling route, providing a scenic backdrop of downtown Baltimore and potentially views of the Inner Harbor. Typical race day conditions in late February see highs around 50F and lows around 35F, with a minimal 12% chance of precipitation, creating surprisingly mild weather for a memorable, pants-optional jog.

This event is renowned for its vibrant, fun-filled atmosphere and significant charitable impact, having grown from humble beginnings to a nationwide movement raising millions for NF research. It's more than just a run; it's a community coming together to make a difference, proving that nothing will stop these "undie runners" from finding a cure. Join the heroes and party animals for an unforgettable experience that combines fun, community, and a powerful purpose.
