About the event
One of the great late season events for this classic sprint triathlon in the heart of the great Pacific Northwest. You start off your journey with a 1/4 mile swim in pristine Beaver Lake. Life guards will be there to assist you as needed. After your swim you mount your bike for a majestic trek around King county and the City of Sammamish up the challenging Duthie Hill. The lollipop route takes you through a scenic route with views of the Cascade mountains and rural farm homes. After dismounting your bike and racking, you capture your score and prepare for your final leg which is a scenic 4.3 mile jaunt around the lake and quaint neighborhoods of Beaver Lake estates. You finish with trek through the enchanted forests of the Beaver. Don't miss this classic event. Registration fills up quickly. All registrants get a classic deluxe long sleeve mesh T-Shir…
