The Kusk0 300 passes through Akiachak. The race goes from Bethel to Aniak and then back to Bethel. From being around penned sled dogs, I figured that they would make a ruckus as they went by. This is about 8:00 pm on the Kuskokwim river on January 17th.
The website for the race is fantastic: K300.org
They even do live GPS tracking of each racer here. You can replay the race in speed time on the page.
