He's riding Dwars door het Hageland today. Don't know if he copes with gravel, but otherwise, this should be right up his alley.
Dwars door het Hageland live on Sporza as we speak. Most interesting thing here is probably Simmons, who used to do insane gravel races in the States, like the Leadville 100, against full time pros and given his recent form in Poland he should be up there.
