Bull of the Woods Trail Races

Welcome to the 10th year of Bull of the Woods Trail Races in Taos Ski Valley, New Mexico! In 2026, we are excited to host two different half marathons, one full marathon, and NEW THIS YEAR a 10K course! The full marathon and TSV half marathon distance will take you to Kachina Peak at 12,481ft then you will continue on to the Northside half marathon course where you will climb Fraser Peak at 12,168ft! 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 &
