June 1st is National Running Day, so why not get a head start on the celebration with a running-filled weekend? Given the Memorial Day holiday, there are sure to be plenty of 5k and 10k races, such as the Bolder Boulder here in (you guessed it!) Boulder, Colorado. Or enjoy a long trail run away from competition but up close and personal with your favorite outdoor open space. Wherever you choose to go, however you choose to participate, get out there and run!
