Go off-road on the first day of 2020 at this 16K and 4-mile trail race on the northern edge of South Carolina. The technical, looped course takes runners over roots, rocks and stream--and provides a good chance to run through the snow. The 4-mile course is recommended for first-time trail racers, while the 16K provides a tougher challenge for the more experienced runner. With a later start time of 10 a.m., you can sleep off a bit of that New Year's Eve partying.
