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. 

unplug & run

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 the Motherlode.


A Message to our TrailBlazers: We need you! Come join us at our Michigan Bluff Aid Station. We have a meeting on May 10th to kick off the planning stage. Check your weekly newsletter for details and how to RSVP. 

Let's get ready to cheer on the Western States runners! 

Weekly adventures

Never a dull moment here, we're always working to find the grandest adventures possible in the mountains. 

From 20-mile training runs with strays picked up on the way to brutal canyon climbs and soaring peaks, this is the place to be if you want to experience the Sierras. Many of our training runs are modified for runners that want shorter distances, so there are varying mileages to choose from. It's an epic day any way you slice it.

Subscribe to us on YouTube for our latest trail running videos.

For our members we offer some great bennies! We have 3-5 mile weekly group runs and longer training runs on the weekends. Our weekly newsletter keeps you up-to-date on what the TrailBlazers have goin' 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.

"How true this statement was not many years back. In fact, I loathed running as a child and student. I dreaded the timed mile. I was never “athletic” and was quite frankly the girl who always got hit in the face with the ball. I mean… EVERY. SINGLE. TIME.

"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.

We're a social bunch, and welcome everyone to join in our adventures. Check out what we're up to out there on the trails, from running and hiking to snowshoeing and skiing.


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! 

Join the fun on the weekend of June 24-25 and volunteer at one of the premiere running events in the world.
