Event Description

Welcome to the Roger's Grove Trail Half Marathon and 10K (Formerly known as the Longmont Trail Half Marathon).

If you want a perfect view of the mountains, a flat and fast course, and a stint around the water...  Well then look no further than our 4th Annual Longmont trail race at Roger's Grove Park. Settled into the heart of Longmont, the Roger's Grove Trail Half Marathon and 10K is a perfect course for the beginner trail runner...

This course is a mix of bike path, dirt trails, mountain views, and a little bit a water. Both the half marathon and 10k will take runners along the St. Vrain Greenway with a trip into the Golden Ponds Nature Reserve. 

Runners please note that the half marathon is a 

2 loop course of the 10k.

 *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.
