Underwear-clad runners will be jogging around Franklin Square on Saturday for a good cause.

The Cupid’s Undie Run encourages people to strip down to their underwear, run briefly around the park, and then party, with all proceeds going towards finding a cure for Neurofibromatosis, a rare genetic disorder.

The run will be on Saturday, February 10 from 1-5 p.m. After the “brief” run, according to the website, there will be party, with special rewards for teams and participants determined by their fundraising goals.
