YouTube user Noren5609 stood out with camera in temperatures that never got too far into the teens to bring you highlights of Penn Cycle's 2013 Ice-cycle Loppet, part of the 2013 City of Lakes Loppet festival, celebrated over the weekend. In ice bicycle racing, competitors on mountain bikes equipped with stud-laden tires make their way across a twisting, winding course staked out on top of sheer ice. Riders compete for a given amount of time plus one lap — in the case of the advanced men racing in the video, 30 minutes.
