Cupid’s Undie Run 2016

The event began at 12 p.m., as people arrived to check their coats (and other clothes) at House of Blues.

101.7’s Colton Bradford was on hand to MC the event.

Groups met up and posed for photos ahead of the run.

The exterior of the concert venue was covered with Cupid-themed decorations.

Jeff, Erin, Stacy (left to right) attended to help raise money for research and a cure for NF, “And to make the most of the open bar,’’ Erin said.

Volunteers (from left to right) Jacob Lyons, Kaitlyn Long, C.J. Van Ness, and Sean Smith checked some 200 people into the venue.

Bob Pacheco arrived dressed as Thunderlips from “Rocky III.”

The race began a little after 2:15 p.m. as people burst out of the concert venue’s doors.

Many of the runners dressed in in pink. Others weren’t dressed in much at all.

One runner hyped the pack as they passed The Landsdowne bar.

The route took the runners around Van Ness Street, to an entrance on the opposite side of Fenway Park.

Most runners took breaks to snap some photos in their undies at one of America’s most historic sporting grounds.

The party continued despite a brief bottleneck getting into the stadium.

Amy (L) and Victoria (R) posed inside of Fenway Park. “I’ve seen so many great bodies, everyone’s so hot!’’ Victoria said.

Lara, Rebecca, Lisa, and Bryan (from left to right) were happy to pose for a photo in the tunnel.

Jamie (L) and Marc (R) pose with the trophy for most money raised by a team. The pair were part of team “Cure NF with Jack.’’

Craig, Katie, and Jessica (left to right) came in costume, but not as Cupids. “It doesn’t matter what you dress as as long as you donate and add to the cause,’’ Craig said.

Hundreds paraded through an empty Fenway Park for the cause.

Race organizer, Lindsey (L) and event MC Colton. “Make me look thin!’’ Colton said.
