Dirty Spokes is proud to support our local trail maintenance groups!

We greatly appreciate the time and energy they put into building and maintaining these trails! Please support your local trail maintenance group!


Dirty Spokes will be handing out medals and prizes to our overall top 3 male and female finishers. We will also be handing out medals to our top 3 male and female finishers in each age group. Awards will be given out when we have enough finishers in to fill the categories. Medals will be given out to the top three finishers in each category.


All participants will be required to wear an ANSI or Snell approved helmet at all times while riding. Penalty is DQ.
No outside assistance is permitted at any time during the race. Racers may assist other racers.
All food and drink for the race must be either carried with the racer or staged in the transition area. There will be no water stops on the course.
You must run or walk your bike out of the transition area.
After crossing the finish line, racers will be directed into a finishing chute so that they can be scored appropriately. We will be using "Chip Timing".
Race numbers must be visible at all times.
Cutting the course is not permitted. Penalty is DQ.
The relay exchange will take place in the transition area. This exchange will be done by transferring the timing chip from the runner to the biker.
In the event of a mechanical, the racer must cross the finish line with his/her bike to receive an official finish time.
Please exercise caution and good sportsmanship when passing other racers on the trail.


We will be using "Chip Timing" for this race. Two person relay teams will need to wear a provided timing chip which will function as their "baton" to hand off to their teammate.


Packet pickup will be the morning of the race starting at 7:00 a.m. to 8:00 a.m.. Race starts at 9:00 a.m. SHARP!


Run 3.1 Miles, Bike 11.0 Miles… that´s right it´s gonna be a run, bike event!

Duathlon Bike Course:
While the course is 11 miles, roughly 20% of it is fast with no extended climbs. The bike course starts out with a fast mile on pavement, giving plenty of time to acclimate the legs to the bike. Riders will then enter a doubletrack section of trail around the lake where they can maintain their speed though the woods. Next comes the dam crossing where there are good spots for passing until the course turns on to narrow singletrack. The only climbing is at the end where riders will go up Johnson´s Mountain and continue up a 1⁄2 mile paved climb to ride down fast singletrack with a few small rock drops before returning to the transition⁄finish area on a paved road.

Duathlon Run Course:
Sharing parts of the same course as the 10k and 21k, this starts out with relatively easy terrain. The course builds up to a final mile of some tough hills on scenic hiking trails.
