10 brewers from Avery Brewing Company, Oskar Blues and Ska Brewing will ride the Second Annual Tour of BoulDurango starting Monday July 19. The tour, born out the spirit of collaboration, is not only about the camaraderie amongst brewers but is also a event to raise money for local charities. It’s a 5-day, 470-mile test of endurance that will find the riders stopping by local breweries along the way. You can follow their journey here.
