1) G'day I haven't ridden the exact course but I have raced different circuits involving the same roads. Basically the climbs are short, longest would be 600m or so, but most of them have enough rise to be perfect for the attacks, but it's not the kind of course where a climber will just float away. Just know when the hills are comign and get towards the front.
2) It WILL be windy, I promise you!
3) And the roads are very dead, honestly I think it's a sh!thouse place for a nationals week.
