The Mt. Sneffels Half-Marathon was created more than 23 years ago by board members of the Mt. Sneffels Education Foundation as a fundraiser to supplement member donations. It is supported by funds from the foundation and by members donating their time and energy to organize the event. Net proceeds from the Race Events benefit the school projects supported by the foundation. MT. SNEFFLES IS EXCITED TO BE PART OF THE COLORADO MOUNTAIN HALF SERIES+. YOU WILL FEEL ALL THE AMAZING RICHES FROM PARTICIPATING IN NOT ONLY OUR EVENT BUT OUR PARTNER EVENTS AS WELL THAT COMPRISE COLORADO’S MOST ICONIC HALF MARATHONS+.
