What Will the Course Be Like?

DIRTY DUATHLON COURSE:

The race will be a run, then bike format.

The course will include the Dwelling Loop, a portion of Van Michael Loop, and all of South Loop in a counter-clockwise direction.

The 5 mile run will take place on the Dwelling Trail and will go counter-clockwise. The 11 mile bike will include Mosquito Flats, Mini-Van Michael Loop, Mosquito Bite, Dwelling Loop, and all of South Loop trail in a counter-clockwise direction.

For those new to Blankets Creek, you will encounter the longest climbs early on in the first 2 miles of the course, then have a few miles of fast, rolling terrain before hitting the final miles of twisty, rocky trail on the South Loop. The terrain is gently rolling with moderate climbs. We expect that the overall winning time will be around 1.75 hours.
