The course


The race begins at King County’s Tolt MacDonald Park. It’s quick, (mostly) flat, and in the beautiful woods of the Pacific Northwest. Runners are treated to spectacular views along the Snoqualmie Valley River trail, which winds its way through evergreen, mossy forests. The race takes place in Carnation, Washington, a quaint little town located about 35 minutes outside of Seattle. Near the starting line of the race are strawberry farms and pumpkin patches, which offer guided tours in case you’re still up for a bit of walking after the race.
