His average at the second check point, after 22 kms I think, was over 60 km/h. He has experience on the track, so yes, I think an hour record attempt is inevitable.
Whilst it's proposed he did well over 400w for GB Nats, and he would need something in the 450w region for the hour to beat Ganna. Not sure he's quite there yet.
He absolutely monstered that, didn't he?
