Ultra4 has just released the dates for the 2021 King of the Hammers race, Jan 28th - Feb 6th. the main change is the main race will be held on Saturday rather than Friday, I think to accommodate some additional races that they're adding.
So far no, it's still a go. They have a pretty good Covid plan in place, plus for that area, the hospitalization rate is pretty good aka low, like 14 people per every 100k are in the hospital. Waiting to see when they'll open up the registration for media folks.
