A women-only event, the Sturdy Dirty is an enduro race on Tiger Mountain, with forested singletrack and views of Mt. Rainier in the distance. Depending on category, riders race between four and six timed downhill stages, and upper-category entrants will tackle the challenging Predator descent. Created by Sturdy Bitch Racing, the Sturdy Dirty aims to give riders a chance to get out and meet other women who share their passion for mountain biking. It sells out quickly, so youll want to register early.

Meet the organizer

Formed in 2010 so a handful of women could race the BC Bike Race together and raise money for the Breast Cancer Fund, the Sturdy Bitch Racing team decided to give back more locally in 2015 after catching inspiration from our sister shredders to the North. Inspired to put on the first women's enduro race in the US—the Sturdy Dirty Enduro—we continue in 2018 to create fun, intimidation-free racing experiences, host women’s rides and trail work parties, race bikes, and give back our time, sweat and dollars to the trails we ride.
