You will span the entire Taos Ski Valley on this course, truly giving you some much deserved trail-cred! The Northside half marathon will follow the previous years, primarily tight single-track course on Northside trail system, maximizing your trail-fun and big-trail-views. Keep reading 'Trail Beta' for more detailed course description. The new 10K course will consist of about 1.2K on mountain roads to bring you up to the base of Lift 8 and then singletrack trails from there to the finish with close to 2,000 ft in elevation gain! This is course is extremely different than the Up & Over 10K earlier in the summer, so be sure to register for both! Trail Beta Bull of the Woods Trail Races are two separate half marathons and full marathon distance trail races that is designed to maximize your trail running experience on a primarily single-track course through alpine forests, meadows, and overlooks that will bring out your inner joy and keep you smiling all the way home.
