The mountains and foothills of Nevada and Placer counties are amazingly beautiful areas abundant with parks and trails, and we take advantage of it any chance we have. Walking, jogging, hiking, trekking, running, fastpacking in Grass Valley, Nevada City, Auburn and beyond.

We are a diverse community with newbies to veteran runners, covering all distances from a couple kilometers to 100+ milers. Before you head out, connect with us because we always have something going on.

Our TrailBlazers are the best out there. Erin McCarthy, VP of the Sierra TrailBlazers, gives a glimpse at what it is to become a runner and the support our running community provides.

"PE class was my least favorite class and while other kids thought it was all fun and games, an easy A, I shuddered at the thought of it. I never believed I was good enough.

The Sierra TrailBlazers engage in community activities and social events to publicize the benefits of exercising. We not only exercise, we give back to our community in a number of ways. We volunteer for trail maintenance and at races, such Western States. And we join with other groups to offer community exercise programs at least once per year.


Every year we volunteer at the Western States Endurance Run. It is a great experience to see ultra-runners complete 55.7 miles through The Wilderness and The Canyons by the time they get to the Michigan Bluff Aid Station. The last of them are coming through as night falls. And all still have 44.5 miles to go!

The 2022 Western States dates are June 25-26. Join the fun and volunteer at one of the premiere running events in the world.
