I started at the trailhead in Sedro-Woolley at US 20 and Fruitdale Road and ran it the whole way to the trailhead in Concrete by the Community Center. I carried my own water and gels. There is no water supply on this trail unless you filter at some creeks the trail passes. It was a nice fall day with lots of leaves on the trail. It got a bit smoky around mile 17 due to some fires to the east.
