All-Out Mardi Crawl
The All-Out Mardi Crawl takes place on February 22, 2026 in Arvada, Colorado, with the Apex Center listed as the event location. It is the 10th annual running of the Mardi Crawl. Organizers note this will be the last All-Out event held at the Apex Center because the facility is changing its programming and will no longer host events like this. The event is designated as an official BOLDERBoulder qualifying event, so finishing times from any distance can be used to qualify for BOLDERBoulder waves.
Race distances and other details
The event offers in-person and virtual options, with courses that use the Ralston Creek Trail and pass through creekside open spaces and nearby golf course communities. It is part of a multi-event series that includes a discount structure when registering for multiple races (25% discount per distance for select series entries).
