Calendar of Half Marathon Races in Colorado

The half marathon distance is a happy medium between the fun 5K and the grueling intensity of a marathon. It is long enough to challenge you and demand respect but not so long that it consumes your life with training. It is intense enough to require a serious commitment but not so intense that a runner regularly feels that he or she is completely consumed with running.

Here you will find a listing of the half marathons registered with JogRunRace for Colorado.
