The Sun Mountain 1km course will be all trail and will be on the Chickadee Loop Trail at the Sun Mountain Trail System in Winthrop, Wa. The course will have about 40ft of elevation gain so it'll be pretty flat but not totally. The loop route will be in the forest and will start and finish at the same place as all the other races and the 25k and 50k runners will be there to cheer for the kids as they finish!
