Drop-in Cycling Groups

Betasso Canyon Loop Mountain Biking Boulder

Mountain Biking
Boulder Mountainbike Alliance

This locally loved mountain biking organization has a full offering of weekly group rides that are all free and open to the public. Most rides happen weekly, April through September, on some of Boulder County's best trails. Beginners will want to try Knobby Wednesday, women who want to connect with other women riders will enjoy the Gurlz Ride, and intermediate to advanced riders will love the Trails & Ale ride, followed by a gathering at a local brewpub. On the second and fourth Thursdays of the month, they have Inclusion Rides specifically designed to create a safe space for anyone who identifies as a BIPOC (Black, Indigenous and people of color), Latinx, and their allies. In winter, they've started biweekly fat biking night rides!

Road Cycling
Full Cycle

Full Cycle offers group rides nearly every day of the week, from Tuesday morning casual rides to Sunday gravel rides. All rides provide the chance to make friends, demo new bikes (reserve first), discover off-the-beaten paths, drink free coffee and enjoy post-ride drink specials back at their hybrid bike shop/coffee and beer bar.

Wednesday Morning Velo

With the Wednesday Morning Velo group, you can mix business with pleasure. The ride runs May-Sept. at 6:30am. Each week, cyclists meet at Amante Coffee in North Boulder and divide into four groups with predetermined routes. (Choose the group/ride that best suits your needs.) Afterward, gather back at Amante for coffee and pastries provided by the sponsor to share stories and business cards.

Cruiser Ride
Happy Thursday Cruiser Ride

This Thursday-evening community bicycle ride meets weekly at 7:30pm at Greenleaf Park and other locations (check their Facebook page for the most recent info), spring through fall. A lively crowd turns up dressed according to that week's theme, from "PirateCon" to "Acid Flashback." Don't expect a workout — this ride is strictly for fun. It's known as one of Boulder's oldest and most eccentric traditions, starting back in the early 90s during the resurgence of fat-tire bike culture.

Drop-in Walking Groups

Boulder Ramblers

Boulder Ramblers provides free community walking, hiking and “rambling trips” in and around Boulder County. The program is part of Walk2Connect, and its focus is on connections to others, the environment and ourselves. 

Boulder Walks

The Boulder Walks program is also in conjunction with Walk2Connect and provides opportunities for neighbors to connect with one another and with where they live. It gives community members an active way to engage in GO Boulder's pedestrian planning activities as a way to invest in a more walkable city. Walks are plentiful! The Boulder Walks Program is currently on pause, but you can find self-guided walking tour maps on their website.

Hey, if groups aren’t your thing, no sweat! These trails and paths are good for all levels and perfect for solo strolls or a workout with just you and your favorite running buddy.

  • Wonderland Lake: This 1.75-mile dirt trail starts on the south side of the Foothills Nature Center (4201 N. Broadway) and will take you around the lake. Keep your eyes on the sky for a glimpse of hang gliders and paragliders launching from nearby Wonderland Hill! 
  • Goose Creek Path: Start just south of the intersection at Valmont Rd. and Folsom St. and head east toward Foothills Parkway. You'll pass by Goose Creek Pond and end up near some of Boulder's favorite breweries (Boulder Beer Company, VisionQuest Brewery and Kettle and Spoke Brewery) as well as Redstone Meadery, if you fancy a post-workout adult beverage. 
  • Boulder Reservoir: You'll have to pay a small fee for access, but this 700-acre, multi-use recreation and water-storage facility is worth it. Walk or jog the 5.25-mile loop trail on graded dirt around the reservoir, best used Feb.–Nov. Watch for wildlife and people plying all sorts of watercraft. 
  • Teller Farm: Head to East Boulder and meander through historic and working farmland used for crop production, beekeeping and cattle and horse grazing, then enter the White Rocks Nature Preserve.
