The Bear Chase Race Endurance Festival is a 100k, 50 mile, 50k, Half … and the Baby Bear 10k Trail Race at beautiful Bear Creek Lake Park, in Lakewood, CO.
Race starts by winding through Old Town Nederland as you make your way to the main race route. The 1/2 Marathon will take you on dirt roads and single track trails as you challenge yourself to be “a little more extreme.”
Set for its 18th annual summertime running between the small southwestern Colorado towns of Ouray and Ridgway, the Mount Sneffels Marathon & Half Marathon takes runners along a high-elevation course that follows an overall downhill descent on the dirt county roads between the two.
The GTIS Half Marathon is one of Colorado’s Oldest Half Marathon Events. It is one of three half marathons in the Colorado Mountain Half Series. Join us for the 41st year of one of Colorado’s most iconic 1/2s.
