The run is 10km using a combination of paved and dirt trails. It will be well marked. The run consists of 1 large loop with a short out and back followed by a shorter 2nd loop. On the 1st loop racers will run out from the transition area heading north along the bike path on the eastern shore of Chena Lake for 1km and then veer left and then immediate north for 1.5 km where the short out an back begins. Racers will turn left at the intersection and proceed 0.5km before reaching the turnaround point. At this point racers will then head east staying on the trail for 2.0km before the trail veers south for an additional 2.1 km before turn right onto the paved bike path and returning back to the transition area and the end of lab 1. The 2nd lap will again follow the trail north for 1km. At this point turn right and proceed on this trail for 0.6km then turn right and retrace you path back to the transition area and the finish. There will be aid stations approximately every 2 miles on the run course.
