Please don't compare these two. Hall was a legit marathoner. Wardian is trying to hold on to something that was never there from the beginning. Wardian is not competitive and never really was so he competes in niche events such as this to garner attention. As soon as he isn't getting the attention he will find another niche.
Think, he tried over racing on road races sub marathon, then after not winning he does it with marathons. He even tried short trail races and found he couldn't compete so he went to ultra immediately. He came to my state for an uphill road race thinking he'd win and got toasted, I think a woman almost got him. When you can't compete then you find small marketed events to win against the little guys. The man is a joke athletically from an elite perspective but he is smart. Ask any pro runner what they think. I've asked a few.
