Ride more than 500 miles of interconnected mesa-and-canyon trails across 5,400–10,454 ft of elevation—expect big views, volcanic terrain, and plenty of technical, high-altitude riding.
Los Alamos is located on a geological formation called the Pajarito Plateau. The plateau is capped by a special type of rock called Bandelier Tuff, comprised of compressed and crystalized volcanic ash deposited by the eruptions of the near by Valle Grande Caldera roughly 1.61 million years ago.
So don't be fooled! The "Tuff" in our name comes from the type of rock we ride on; not because we're "tough". In fact, we take great pride in welcoming riders of all ages and skill levels!

New to riding? New to elevation?
The town of Los Alamos only has a couple true 'GREENS'. Check out Kwage Mesa Trail or Bayo Canyon if you are just starting out.
Our weekly rides are not usually ridden on green trails, but we do have easy riders in our group! Reach out ahead of time to coordinate an easy ride if you are interested.

Our weekly group are mostly on Blues and Blacks. If you think you're up for a group ride, try a piecing together a few of these Blues on Trailforks:
Non-Technical Perimeter, Berm City, Rendija Bench, Dot Grant, Walnut Canyon, and North Pueblo Bench (bridges).
Intermediate Group Rides average about 10 miles with at least 1k ft of elevation gain and last around 2 hours.

Our Advanced weekly group riders will ride a combination of blue and black trails, but at a consistently faster pace than our Intermediate Group. This group does not stop for water breaks or at the top of hills to rest.
If you think you're ready to ride with these Tuffies, try riding up and down Quemazon Trail or down Pipedream.
Every Tuesday & Thursday at 5:30 from May-September
