BARR LAKE HALF MARATHON AND 10K

Join the Endurance Race Series as we head to Barr Lake State Park in Brighton, CO for our newest and 1st Annual trail race around the lake.

The course is our flattest and fastest on the ERS schedule with less than 100' of elevation gain for either course. Runners will start and finish at the Nature Center and make their way around the lake during this out and back course that features views of the lake and the front range the entire way.

This event is limited to 250 runners

The deadline to order a shirt has now passed. if you would still like to purchase an event shirt, you may do so onsite once you finish the race. please see registration tent onsite for all remaining sizes

Please note: State Park parking fees may apply onsite

*We have adjusted our prices, so that they do NOT include a race shirt. If you would like to take advantage of the shirt option, it is $5, and can be added in the Swag area of your registration.  For those runners adding the shirt option, we ask that you register at least 10 days prior to race day, to be guaranteed of your shirt order. If you are within the 10 day window, we will ask you to pick up your shirt after the race, from the sizes available. We will do our best to accommodate all requests.
