I'm with Hippy on this. Blatant blocking it was not - and Farrar did what he should have done - pushed him out the way....
Renshaw could have done the same to Dean as Dean "leaned into him" (which he did), but at sprinting speed had to use his head...... O.K., the very last headbutt was too much, but fatigued in that heat - his passion and deisre to get Cav across the line overpowered him.
Cycling needs to HTFU some more...
Dead right.
