Crooked Gravel
2026-08-01 08:00 - 17:00 | Winter Park, CO, Winter Park, CO, United States
High Mountain Gravel, Live Music, Trail Run and Fun for the Whole Family
Crooked Gravel takes a few cues from an exploratory event the legendary Ron Kiefel put together a decade ago called Crooked Roubaix. Back before gravel bikes were really a thing, Kiefel and some friends set out on a 95-mile dirt-road adventure from Winter Park up into the high mountains on road bikes. Fast forward to 2025 and we’ve all become part of the exciting world of gravel.
Winter Park, Colorado has hundreds of miles of smooth and stunning gravel roads featuring beautiful wildflowers, Aspen groves and babbling brooks.
The short course packs a perfect punch — 25 miles of rolling terrain, flowing gravel, and wide-open mountain views before looping back into town. Fast, fun, and scenic, it’s the ideal mix of challenge and reward.
Looking for more? The long course turns things up a notch — more miles, more climbing, and even bigger views. You’ll top out at 10,500 feet after a 12-mile, sustained climb that will test your legs and fill your lungs with that high-country air. It’s tough, wild, and absolutely unforgettable.
Two courses. One epic ride. 25 or 67 miles of pure Colorado challenge — climbs, views, and grit at 10,500 feet. How far will you go? Push your limits on Colorado’s most scenic and challenging gravel routes.
If nothing worth doing is easy, then Crooked Gravel is definitely worth doing!
Check the schedule for all of the details for the weekend events!

Breck Epic
2026-08-10 - 2026-08-15
ABOUT THE RACE

EPIC XVII- AUGUST 10-15, 2025
Yeah. Um…about that. We ripped it off from the Canadians. Who ripped it off from zee Germans. Who live next to the Swiss.
So why Breck Epic?
Let me explain. No, there is too much. Let me sum up; The Breck Epic. Back to the beginning. When mountain biking was about big rides with friends. About lending a hand when a rider went down. About a shared experience that somehow, flying in the face of all logic, disproportionately enriched all involved.
The Epic is composed of 6 BIG backcountry loops (3 loops for the 3-day Epic-curious events), each between 35 and 50 miles long. The event is unique in that it employs a cloverleaf format; each loop starts and finishes within a mile from downtown Breckenridge and utilizes the sprawling network of trails in both Summit and Park Counties. When mapping out the courses we asked ourselves; “What big rides would we want to tackle if we had most of the day to slaughter and 6 of our best friends?” The answer lies before you. The six stages that compose the Epic are a well-rounded rider’s dream. Long rhythmic climbs followed by endless descents that make your smile muscles hurt.
In a bizarre way, we have the assorted governing bodies to thank. Mountain biking seemed like an afterthought for many, many, many years. We’ll grant that that’s changing and it’s important to acknowledge that that doesn’t happen with someone pushing it from the inside. But the unintended result of being treated like the proverbial redheaded step-child for a decade-and-a-half is 6-day race in Breckenridge, CO that lives among a small but thriving handful of kick-ass bucket-list races.
Of course, we’ve added a few things along the way. The Women’s Cycling Summit in 2023. Breck Bike Week collab with the Town of Breck in 2024. The Breck Epic Women’s Tour (2024) and the MEGA EPIC (2024), an exercise in ultra endurance madness.
The core race tho? It’s rad. The courses are beyond fun. The vibe? Mid-90’s mayhem. If that sounds like your cup of tea, come join us. We’ve got great people in a great town with courses that you’re gonna need to ride to believe. What else do you really need?
Wanna throw your hat into the ring for 2025? In the immortal words of Levon and Barry, “Awwwwww YEAH.”
