Hitting a brick wall at 60km is going to be really bad, I was gutted for him when I heard this last night.
He will not be able to take part in la Tour Dr France for some years, and even if he does I think he's lost his form as shown last year with Geraint.
He will be devastated I would think.
But on the plus side, he's incredibly disciplined and determined and he may surprise us all.
I wish him the very best. @masterluke
