The B360 & B180- Circle Boulder By Bike is a family-friendly cycling event that explores some of Boulder’s 300 miles of bike routes, paths, and lanes. offering two loop options: a 24-mile (B360) or 12-mile (B180) ride around the city of Boulder. The ride begins at Valmont Bike Park (3160 Airport Road, Boulder) on Sunday June 1, 10 a.m. to 2 p.m.
This event’s an awesome way to explore Boulder! The B360 takes you all the way around the city, while the B180 gives you a different view. The official start time is 10 a.m., but feel free to hop on the route anytime before noon—everything will be clearly marked.
Along with cruising around Boulder and soaking up the views with your fellow riders, we’ve got some tasty perks—grab a bagel from Moe’s Broadway Bagels before you hit the road, and cool off with some ice cream after the ride!
New for 2025 at the B360: Scavenger Hunt with Limited Edition Prizes

What is a spoke card? Spoke cards are a popular cycling tradition that dates back to the 1930s. They are small cards that are attached to the spokes of a bicycle wheel and rotate when the bike is in motion. The cards were originally used as a way for cyclists to express themselves and are a fun collector’s item. Read more about the history of spoke cards.
