Colorado's Largest Trail Race Series

Race Schedule

Westminster Trail Half Marathon, 10K, 5K

​Join us Saturday, April 29th for the Endurance Race Series' annual kick off event.  

Start your trail running season off on the right foot with this flat and fast course along the Dry Creek trail system. A great race for those competitive, intermediate, or novice runners. The trails are mix of packed dirt trails and bike path.

Although we have moved the event away from the Easter holiday, we will still be offering up one of trail racing's best post race festivals, with a pancake breakfast, coffee, hot chocolate, raffle prizes, and other fun family activities.  

Our race has been moved back to the original start/finish location next to the Armed Forces Tribute garden and the softball fields. Pleas check out the event site map for details
