Steamboat Marathon - Colorado
Colorado is known for its absolutely beautiful mountains and that is what you can expect from the Steamboat Marathon! Enjoy running through the notable sights of snow-capped mountains and green pastures on this admirable course beside the rushing Elk River. Held every June for the past 10 years, this race is a favorite among both locals and those from out of town because of their motto that every runner matters.
