ST. LOUIS, Mo. – This year’s Annual Cupid’s Undie Run had a slight different look from those of the past. A smaller, in-person pre and post-run gathering hosted at PBR in Ballpark Village followed by a virtual event for those not able to attend the limited-access event. Held around Valentine’s Day, it’s a one-mile (ish) run in downtown St. Louis while donning your best boudoir attire. They’re not crazy, just crazy serious about raising money for The Children’s Tumor Foundation.
