Even though vaccine rollouts underway to ensure we can offer a safe and socially distanced event, we will once again be virtual in 2021. Participates will have from June 1 – 19 to run the course and report your time.


The Round Valley Rambler offers two distances, 7K or a trail half marathon. The half marathon distance is the first race in the Triple Trail Challenge 100% of the course takes place on buff single and double track trails within the 2,100 acre, Round Valley Open Space, with altitude ranging from 6,500 to 7,100 feet. While athletes will find the trails foot-friendly, the rolling, high-desert terrain presents a few long and steady climbs followed by fast downhills. With the new Virtual format, all abilities are welcome, you can run, jog or walk anytime throughout the month of June.

The Round Valley Rambler is a stout trail half and serves as a reality check for athletes preparing for the Triple Trail Challenge sister races, the Jupiter Peak Steeplechase and the Mid Mountain Marathon.
