Raw athleticism streaked through Central Park Friday evening bared for a modest body of spectators.
Two-hundred triathletes ran a skimpy 1.7-mile loop in their underwear to flesh out the opening festivities of New York City Triathlon weekend.
Midriffs and tan lines rippled in the open air and a not-so-tighty finish saw the first male and the first female finishers undress the course in record time.
The underwear run allows us to see a different side of these triathletes before they're cramping and sweating and looking like they want to die on Sunday.
On this revealing night of mischief and intrigue, athletes gave each other some skin exposing the true spirit of the event before stripping away any emphasis on appearance and testing the performance of their sinewy forms come race day.
