All-Out Mardi Crawl

Apex Center, Arvada, CO
Half Marathon
Important (and sad) news
This will unfortunately be our last event at the Apex Center. Their programs are expanding, so they can't host events like ours any more. If you love the Apex Center like we do, make sure to attend this one last All-Out event there!
Enjoy a wonderful winter run and celebrate Mardi Gras in true Colorado form at the 10th annual Mardi Crawl! 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' counterparts Summer Breeze and Runapalooza, offers a can't-miss opportunity to experience the best of what Colorado has to offer!
Location
