Sled dogs run through the streets of Akiachak, Alaska, on Aug. 18, 2023, training for winter mushing competitions while tethered to a four-wheeler instead of a musher's sled. Nearly 700 people live in Akiachak, a subsistence community located on the Kuskokwim River in southwest Alaska. While the Iditarod Trail Sled Dog Race is the world's most famous race, Akiachak residents are just as familiar with the Kuskokwim 300 sled dog race that starts in nearby Bethel, Alaska.
