Ready to freeze your buns off for a good cause? Cupid’s Undie Run brings hundreds of brave souls together to run a “mile-ish” in their underwear — all to raise money for neurofibromatosis research through the Children’s Tumor Foundation. The event kicks off at noon with music and dancing, the run launches at 2 p.m. and it wraps up with a dance party. Since 2010, Cupid’s Undie Run has raised more than $25.7 million nationwide to fight NF. It’s ridiculous, it’s cold and it’s for a great cause.
