Just to add: he has always said that after the Olympics he is retiring (at age 25). He has not confirmed it as far as I know, but he has hinted at it in interviews and also in this document. He basically took the long distances in speed skating by storm, and is now doing a massive mic drop.
He has said in interviews after winning his two gold medal that he's going to try to stop, but since he tried that two times before, there's a 20% chance he'll be back.
He also said he doesn't know what he's going to do the next few years, but that there are a few ultra runs he still wants to do.
