All-Out Mardi Crawl

New half course - weather update

The half marathon course has been rerouted and aid station moved due to the snow. Please visit the course details page for more details. The 5K and 10K course remain unchanged.

No matter what distance, be aware that the trails are plowed and most all are dry and bare concrete (except the portion of soft surface in the 10K/half marathon trail detour), but there can be small areas of ice and slush from melting snow, so we recommend trail/waterproof shoes if you have them and being aware of the course conditions as you're running.

NOTICE: COURSE DETOUR
Construction just started on a section of the Ralston Creek Trail, affecting 10K and half marathon courses. We measured 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.

Thank you for joining us!

We hope that you had just as much fun as we did at Mardi Crawl!
