Come celebrate with us!
All-Out Mardi Crawl
Saturday, February 22, 2025 9a
Apex Center, Arvada, CO
NOTICE: COURSE DETOUR
Construction just started on a section of the Ralston Creek Trail, affecting 10K and half marathon courses. We just rode the detoured course and have created new course maps and aid station locations. See the new maps on our Course Details page.
The new course means there are greater distances between aid stations and one less toilet stop, unfortunately. However, all aid stations are within 2 miles or less of each other.
Half Marathon
Enjoy a wonderful winter run and celebrate Mardi Gras in true Colorado form at the 9th annual Mardi Crawl, benefiting Firefly Autism! From the award-winning Apex Center, you'll have the chance to tackle relatively gentle 5K, 10K, and half marathon courses that go along the acclaimed Ralston Creek Trail, taking you through shady, creekside beaty along Arvada's picturesque open spaces and charming golf course communities. This event, paired with its Endless Series' counterpart Runapalooza, offers a can't-miss opportunity to experience the best of what Colorado has to offer!
Location
