Capt. Erin Rost, 319th Recruiting Squadron operations flight commander, climbs up one of the Twin Peaks obstacle in the World’s Toughest Mudder, Nov. 10-11, 2018, in Fairburn, Ga. She earned second place out of 231 females and ranked 18 of more than 1,206 participants. The Air Force Academy graduate repeated the course's grueling five-mile lap that contained more than 20 mud-drenched obstacles in frigid temperatures until she met her personal goal of 75 miles.
