For any cyclist looking for a winter adventure, the Old Man Winter Bike Rally & Run is an event organized by Adventure Fit that should be high on your list. Set against the stunning backdrop of Lyons, Colorado, this endurance festival offers mixed-terrain adventures for all levels of runners and riders. Scheduled for February, this event promises a unique combination of challenging courses, a vibrant community atmosphere, and rewarding experiences that cater to competitive athletes and recreational participants alike. Strambecco rates Old Man Winter Rally as one of the Best Gravel Cycling Race Events in the Rocky Mountains region and one of the Best Gravel Cycling Race Events in Colorado.
What sets the Old Man Winter Rally apart is its inclusive nature, welcoming runners and cyclists of all skill levels. Whether you're a seasoned trail runner, a gravel grinder, or a weekend warrior, you'll find a category that suits your abilities and ambitions. In addition to the physical challenge, participants will enjoy live music, bonfires, food vendors, and a lively post-race party, making it a memorable winter festival for everyone involved.
The Old Man Winter Bike Rally & Run began as a nod to founder Josh Kravetz's winter training rides with friends in Texas, known as the “600 Minute Ride.” After moving to Boulder, Josh was inspired by Colorado's winter terrain and created a rally to bring people together for a rugged, adventurous ride in any weather. True to its origins, the Rally is about camaraderie, adventure, and getting outside—whether in snow boots or shorts. Following the success of the first year, a 10K run, a 5K, and a combo were added, as well as an epic after-party to celebrate the day’s achievements.
Weather is a defining element of Old Man Winter, adding unique challenges and unforgettable memories every year. From sunny, 60-degree days to snow-covered trails, every event brings its own surprises, capturing the spirit of adventure. Boulder’s typical February weather averages around 45°F and sunny, but as always, Old Man Winter may have other plans!
Below you will find information on course details, lodging, dining, and other outdoor activities to do while in town for Old Man Winter Rally.
Event & Course Info
The Old Man Winter Bike Rally & Run is primarily a mixed-terrain cycling event held in and around the picturesque town of Lyons, Colorado near Boulder. Designed for cyclists of all levels, the rally features three main cycling events: a challenging 100K (75mi) ride, a more moderate 40 mile ride, and a 23 mile event, perfect for those looking to dip their toe into winter mixed terrain adventure riding. All courses showcase the stunning landscapes of the region, incorporating dirt trails, gravel roads, and scenic routes that highlight the beauty and rugged terrain of Colorado.
For the Old Man Winter Bike Rally, riders bring everything from road bikes to fat bikes, but gravel or cyclocross bikes are ideal due to the mixed terrain. Tires should be at least 25mm wide, and knobby treads are recommended for traction. If conditions are dry, a road bike with wide tires could offer speed, though a fat bike will win in fun and high-fives!
Check out the new course options for the 2025 event:
75 Mile Bike

Heil Valley Ranch is another excellent option for winter sports enthusiasts.
