Ride great gravel routes! / 14,000+ miles!

Gravel cycling is our passion. We provide free, five-star, hand-curated gravel ride guides across the Western United States and Tasmania (with a big focus on Oregon and Arizona.) All so you can connect to where you ride … and learn about the culture, history and environment. We hope to inspire you to get more involved!

We do this out of our love for exploration, community and giving back! We are a 501(c)3 non-profit organization. All of our content is free and open to the public. All that we ask is that when you use a Dirty Freehub ride guide, give us a shout-out in your social media posts or the other places you share content (like Strava) and provide a link back to the ride guide on Dirty Freehub.

And … if you think what we do is really cool, and you want to see more routes and ride guides developed, donating to the Dirty Freehub Project is one way you can make this happen.

McCool

5 Star (Quick Build) Route
~ Bend, Oregon
The ride meanders around Davis Lake and skirts past Wickiup Reservoir. Beyond the (mostly) easy and flowing miles, this route rewards you with some amazing wildlife viewing. We've spotted a mother wolf with pups, plus flocks of white pelicans mingling with seagulls. This area is also buzzing with bald eagles and ospreys thanks to the mix of shallow lakes, lava beds, and pine forest that makes up the terrain.

Opal

5 Star (Premiere) Route
~ Prineville, Oregon
You will like this route if you like: up gravel down pavement riding, beautiful forests with big trees, vista views of the rounded mountain tops of the Ochocos and few people. But before you hit the download, look at the hill profile closely. The route starts with a tough climb and ends with an even tougher climb. The roads are rugged, the area remote.

Bull Prairie

5 Star (Premiere) Route
~ Lakeview, Oregon
On this gravel ride, explore the beauty of Bull Prairie with wide open skies, stunning views and a fun, no-brake finishing descent. We love this route for so many reasons. The wide open prairie, cinder red gravel roads that should be the next color for a Crayola Crayon. Black angus cows that perfectly decorate the landscape, huge ponderosa dripping in chartreuse wolf lichen. Frogs chirping in cold running streams.

Dirty Aufderheide

5 Star (Premiere) Route
~ Eugene, Oregon
This route reimagines the classic Aufderheide as a mixed-surface adventure—building on the iconic classic road ride while pushing deeper into the surrounding mountains. It follows roughly 90% of the traditional Aufderheide route, periodically branching off onto remote Forest Service roads that climb high above the river corridors and into quieter, more rugged terrain. The result is a true backcountry experience.

Bikepacking Route

The Deschutes River Rambler (DR2) is a 300-mile bikepacking route that traces one of Oregon’s most iconic rivers from its source at Little Lava Lake to its confluence with the Columbia River.

From the cool forests of the Cascade Mountains, the Rambler rolls through volcanic plateaus and river-cut canyons toward the Warm Springs Reservation.
