Between November and the end of February, thousands of trail races will open registration for 2026 (including The Bulldog Ultra, pictured above 😍). Many of them will sell out before you finish your next long run. 😅
So if your 2026 goals include PRs, new distances, or finally signing up for that race your friend swears is “totally runnable,” this is your moment.
Below you’ll find the races that are opening registration on November 15, those that opened in early November, and others that will be opening soon. Scope them out, make your picks, mark your calendar, hit register. The 2026 version of you is already stoked you signed up early.
So go ahead — fill that race calendar, chase that buckle, and make future-you proud. ✨
See you at the start line.
