Boulder’s Valmont Bike Park has been under construction since October 2009, but city officials have scheduled the opening day for June 11. The 40-acre facility will benefit locals as well as riders from around the world. Occupying a section of the 132-acre Valmont City Park, the bike park will feature a variety of biking terrain, from cyclocross trails to a section for kids on tricycles. There will also be a large network of single-track trails. As the final touches come into place, many biking enthusiasts in the region anticipate the park’s opening this summer.
