Matt, the 72 hour winner is phenomonal, he actually got close to William's distance for his first 24 hours, he's run on the US 24 hour team then run 130+ miles 2 weeks later in the US championship, and that wasn't much before Across the Years. He's also very friendly and quite happy to talk to me if we coincided on the way round.
Last year he ran the 48 hour race and set the US record of 400km.
This year they'd made one special 300 mile award, hoping he'd get there, I think he had a few hours to go but stopped anyway for some reason!!!
