Coming February 6, 2016. Are you up for a challenge? Try the Polar Bear Challenge at Shale Hill Adventure Farm in Vermont. It’s more than 10K, over 60 obstacles, trail running, with hills, mud, ice, snow, and winter temperatures! Obstacles include the Cliff Jumper, Tarzan, Pond Traverse, and the Warped Wall. The big winner will be the person that completes the most number of laps in 8 hours. If you’re not up to doing multiple laps, this year they are offering a single lap option for the 10K and 5K course. A chilly, fun challenge!
