Swim: Triangular lake swim (water temperature in the mid to upper 60's).
Bike: Semi-closed course (local traffic only) on an out-and-back, westbound on Marine Drive, on a newly paved road. The Olympic distance races will also have a 7+ mile out-and-back to the east of Blue Lake Park on Marine Drive, Sundial and Graham Roads. This section of the course is open to traffic, but lightly traveled.
The bike portion of the event is flat and fast with the majority of it on a section of Marine Dr that is closed to all but local traffic. This makes this course one of the safest and fastest in the region. The Sprint course falls entirely on this portion of Marine Dr and participants rarely encounter a vehicle. The Olympic course has a 7-mile section that goes south towards I-84 to the Troutdale Airport and back on quiet, lightly traveled county roads.
Run: Flat and fast within Blue Lake Park, with an out and back section on the Marine Drive bike path. Aid stations with water & electrolyte: two stops on the Sprint course and four on the Olympic course. All miles are marked.
