Save the Date! Saturday, August 17th, 2019!

Join us on Saturday, August 17th at Wahlfield trail for our 6th annual Skirts in the Dirt mountain bike race! Our event is more than just another mountain bike race -- it is a celebration of all women who ride! Cis, trans, non-binary, and femme. mountain biking is awesome, and the people are even better! 

Skirts in the Dirt is free for those 12 and under!

We take pride in cultivating a safe place for all non-traditional mountain bike riders to comfortably experience a beginner-friendly racing atmosphere. It is our hope that it leads to more races down the trail. :)

More info on our FREE pre-race skills clinic coming soon!

Thank you to our community for supporting this event. <3

Why Race?

There are a lot of reasons why we encourage you to race mountain bikes! We love seeing everyone learn, get stronger, ride further, and all of the friendships that come from spending time together on the trails. Having a race on the horizon can help push you to spend more time on your bike - and we love that!!
