The Mile 101 checkpoint is a cabin at mile marker 101 (the distance from Fairbanks) on the Steese Highway. At Mile 101, mushers have the option of taking their four-hour rest during even years. They can also take the rest at Central during even years. Again, the three minute start difference will be subtracted from the race if the musher desires to take their rest here. The cabin gives mushers the opportunity for a short rest between Eagle Summit and Rosebud Summit. The ascent of Rosebud Summit begins about south of the dog drop. It consists of a gradual climb of followed by a steep descent into the valley that contains the north fork of the Chena River. The descent also brings mushers back into forested terrain. The trail then parallels a road for about before entering the final checkpoint at Twin Bears Campground near Two Rivers.
