The 6th annual Summer OPEN Sprint Triathlon is the kick off to the Colorado Triathlon Season, and we kick it off in style! It's time to dust off the bike and pull the wetsuit out of the closet for this Colorado spring classic. This race, the 1st stop on the Colorado Tour, takes place at Union Reservoir in Longmont! From beginners tackling their first event to veterans tuning up for a competitive season the Summer OPEN is about friends and teammates, smiling and cheering.
Men's or woman's cut technical t-shirts are back in our traditional Summer OPEN "Red". Great goodie bags, one of our biggest expos of the year, a ton of raffles, and a closed race course are just some of the highlights. This race is capped at 500 athletes to maintain a fun, yet lively, and laid back feel. Due to the low cap we've sold out the past 5 years so be be sure to take advantage of early registration.
