Welcome to the 9th year of Bull of the Woods Trail Races in Taos Ski Valley, New Mexico! In 2025, we are excited to host two different half marathon and one full marathon distances! The trail marathon and the 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.
