Run your way through the masses to feed the masses. More than 10,000 racers take part in the annual charity-based and entertainment-packed run. The Sneak consists of five different races - from a 10-mile run to a 1/2-mile kids' fun run. After the running, a block party brings everyone together through vendors, a beer garden, and a fun zone for the kids. Proceeds benefit Food Bank of the Rockies, which doles out food to more than 1,000 programs in Colorado and Wyoming. Sun 7 a.m.
