Explore the trails of Colorado in 2019. The Series consists of 4 trail races and a winter obstacle run. Each race features a short and long course, and all races are open to runners of all abilities. The Series is cup-free - participants MUST bring a reusable water bottle.

The winter obstacle Abominable event are not for those warm weather loving folks; we are all about celebrating everything winter has to offer. This winter adventure run will have your heart racing and not just because of the 10,000 foot altitude, this fun yet challenge course will have you climbing over and crawling through obstacles, running in deep snow through scenic woods and fields and sledding down steep inclines.

Colorado Trail Run Series is hosting the famed XTERRA Trail Runs. Starting in April 2019 all trail runners will ascend to peaks offering spectacular views and all distances will include breathtaking single and double track trails. While experienced runners will enjoy the challenge and exploration of new territory, those new to the trails will also discover a whole new world of running where it is perfectly normal to walk the hills and save your energy for the flat and downhill sections. All finishers will receive custom finisher medals, custom tri-blend t-shirt and some cool swag. We also host local running related training sessions and host the Trails in Motion Film Festival in Denver and Colorado Springs. Please join us for another amazing year in "Colorful Colorado".
