Beautiful Race Route

Regardless which distance you choose on race day, you'll definitely enjoy running on the beautiful Boulder backroads. The race route takes runners through the beautiful farmland just north of town, with breathtaking views of the Colorado Rockies and Longs Peak as you run along. If you've never experienced running on the backroads, you're in for a treat as the running surface is much more forgiving than pounding the pavement! Get your friends and family registered today, and we'll see you on May 4th!


Runners & Walkers Welcome

The best thing about our events is that we cater to all types of runners and walkers. Regardless whether you're trying to run a personal record in the half marathon, or you're simply walking the 5 Mile, the event has a distance for you. And the Boulder Spring Half Marathon race course is open for a full 4 hours on race day, so if you're planning on walking, you'll have plenty of time.


More Value for Your Registration Dollar

We try and give our participants more value for their registration dollar than they find at other races: All of our Boulder Marathon event participants receive a high quality technical running shirt with race logo, a race course with aid stations stocked with food and drink, a beautiful finishers medal, high quality race timing (with new disposable timing chip!), lots of quality post race food, and of course the Boulder Beer garden!


Spring Half Race Cap of 1,500 Participants

In order to maximize the experience for all runners and alleviate some of the congestion at the reservoir, we are capping the Spring Half at 1,500 total runners. We expect to reach our race cap in advance of race weekend, so register today to secure your spot at the starting line on May 4th!
