Could be quite an interesting race. Australia will be focusing everything on bringing it back together for a sprint, but:
(a) Even with Australia's superior team, that's not easy to do. Rarely do Commonwealth/Olympic road races end in bunch sprints even on flat courses. (Edit: In fact, looking back over all Commonwealth and Olympic Road mens' road race since 1980, I can't find a single bunch sprint for the gold)
(b) If it is a bunch sprint, who will Australia be riding for? I would have thought Renshaw would lead out Ewan, but it's not certain and they're not revealing their plan.
I'll be hoping other teams attack repeatedly and Australia can't keep it together. Geraint Thomas or Jesse Sergent for the win.
