On Feb. 9th, thousands of runners will drop their pants for charity in Downtown St. Pete! Cupid's Undie Run is an annual 'brief' run to raise awareness to find a cure for neurofibromatosis (NF) through fundraising for Children's Tumor Foundation. The run starts at Yard of Ale St. Pete and will travel down towards The Vinoy and back. The quick run is followed by a large block party featuring a live music stage, beer garden, and dance party will all happen right on 1st Avenue North between 2nd and 3rd Street North. It starts at 12 p.m.
