It's been a few years since the series has traveled south, but it's time!  The Parker venue was host of the 2018 & 2019 Colorado State Championships. It’s a course that's twisty like a Formula 1 track, yet flows like your favorite roller coaster.  This year well add in a few fun run-ups, toss in a wide course feel, and blend it all together with some spicy lines for high action!

The unique 360 degree views of the Maroon Bells, San Juan Mountains, and the Gunnison Basin, make for a great day out on the trails. The race offers some technical slickrock, some smooth singletrack, and doubletrack for speed.
