4.167 Miles of Pure Joy



Odd numbered laps will be run counter clockwise

Even numbered laps will be run clockwise

The course begins at Butterfield Trailhead Regional Park. This trailhead offers direct access to the amazing Butterfield trail system. You will follow a well made and smooth trail that climbs slowly over the first 2 miles. Once you have reached the halfway mark you will begin the downhill part of the course on great and easy to follow trails. These trails wind through beautiful and dense foliage offering terrific views.

We will alternate directions each hour to switch it up but also take advantage of the different views. The map below shows the counter clockwise profile.

Plan for a day filled of fun in the mountains. We recommend bringing some sort of hydration such as a camel back or water bottle. We will have some snacks and food that becomes more substantial as the race continues. Come prepared with what you are used to having. Better to have it and not need it. Come prepared for the worst and hope for the best!
