2026 has arrived and races are opening registration every day! Check out the list below for races opening on January 1.
The new year rewards the bold ones — the runners who commit to the goal knowing that the perfect training week, the perfect weather, and the perfect moment may never arrive. It’s time to do it anyways. Early registration is the spark that turns “someday” into “I’ll see you there.” Spots are moving, plans are forming, group chats are buzzing, and every bib claimed now is one more teammate added to the season. No pressure, just momentum. Let’s start 2026 strong — together.
Don’t wait—lock in your spots, plan your season, and get ready to chase some epic miles!
