Corridas de Half Marathon perto de Empire

The All-Out Spring Fever is a spring race held on the Ralston Creek Trail close to Golden, Colorado. Runners can choose between 5K, 10K, and half marathon distances. The courses run alongside Blunn Reservoir in Arvada, offering views of Table Mountain and the Colorado foothills, giving it the feel of a foothills trail run rather than a city race. This event is organized by All-Out Multicourse and serves as the spring complement to their Kooky-Spooky series. The race features a bee mascot named Buzzby, benefits the People and Pollinators Action Network, and offers a chance for participants to qualify for a BOLDERBoulder starting wave. A virtual half marathon option is available for those who wish to complete the distance remotely.

The Colorado 13er begins at the Home Depot on Dillon Road in Louisville, Colorado, offering a 13.1-mile half marathon, a 10k, and a 5k on the same race morning. The half marathon starts at 6:30 AM MDT, with the 10k and 5k following at 6:40 AM MDT. Runners aged 14 and older are eligible to participate. The half marathon follows a loop through Louisville, featuring views of the Flatirons. Nine miles of the course consist of flat, crushed gravel, positioning it between trail running and road racing, distinct from a pure pavement event. The 13.1-mile course includes 10 water station stops and 5 portable toilet stops. All race distances are mechanically measured. Half marathon finishers will receive a 13.1 medal, and approximately 30 percent of participants report this as their first race.
