All-Out Summer Breeze

We're the 5K, 10K, or half marathon you're looking for! We have 10 wonderful annual events that give you flexibility in choosing your distance every event (and upgrading or downgrading as you need). Our events are perfect for friend groups, families, dogs, and strollers, for walkers and runners alike, so that everyone can participate and achieve their fitness goals. We like to have fun at our events, with each having a theme and costume contest, but also mean something with a benefiting charity for each event where All-Out matches all athlete donations to the charity. Our events are community-sized (300-800 athletes), which means you won't get lost in the crowd and have a great chance at an award, but it's still large enough to feel like you're a part of something. We run on the region's concrete trails with some soft surface segments, and vary in difficulty from mostly flat to hill climbs. We focus on providing a great experience, including soft swag shirts or other great clothing item, finisher's medals for all distances, aid stations every 1.2 to 2 miles, post-race meal that includes breakfast burritos, tons of toilets at the venue, and other delightful surprises. And although we're community-sized events, we are a great Colorado experience for visitors from all over the world! We're also good training runs to prepare you for the larger Colorado events like Pike's Peak, BOLDERBoulder, and Colfax Marathon. And we aim to make it affordable to participate in events--check out the Ways to Save page for all the ways you can save money on event registrations.
