Course Details

 The PX 160K course is made up of 96% gravel county roads and 4% blacktop county roads that wind throughout northwest Las Animas county. Each distance has only 10 K of blacktop. Unlike the Leadville Trail 100 or Rocky Mountain Endurance series, each distance contains mostly new terrain. Consisting of rolling foothills, forests and open plains with stunning views of Fisher Peak. 70% of the course is in tree sheltered or canyon areas that are less susceptible to wind. So it’s unlikely you’ll face the winds of Dirty Kanza .Roads are open to public vehicle traffic as well as cattle (open range). Much of the course travels thru historic mining areas. In the unlikely possibility of snow, roads will be plowed and ready to race within 24 hours. Elevations range from 6,000 feet to 8,800 feet. Typical temps range from 50 degrees at start to a high of 75 degrees. Put away those heavy Dirty Kanza tires. These roads are fine gravel, so lighter tires can be run. Rain or snow makes the conditions fast. If you hate competing with cars and love riding quiet gravel roads with some double track, then this is your event. This course will not disappoint! All participants must have a GPS, as the course is unmarked and can be downloaded to your GPS.

 Road bike, cross bike or mountain bike, which will be faster? You should be able to finish the course on a road bike with wide tires but it will be a challenge - with so little road sections there is little area to make time and you will be slow on most of the course. Cross bikes will do well on the climbs and straight flats. Keep in mind that the course has many twisty sections where mountain bikes tend to be faster. Mountain bikers who set up their bike with light tires should do very well on the descents and on the endless curvy areas. A good tire combo is Schwalbe Thunder Burt rear and Rocket Ron.

Support Crews 

Allowed but not required. May only give support at fueling stations. Event will provide drop bag service to first and last fueling station. Support crews will be required to use specified non-race routes to fueling stations .Although we recommend having a support crew , we do not believe that they will provide a distinct advantage. 


GPS, working head and tail light (micro light is acceptable), helmet. Maps will be available as a back up. For the 85 K distance, maps should be adequate.
