Which years did you ride? I know there have been some wet events in the past but 08 and 10 were bone dry. It should be pretty dry up there at the moment unless we get some rain during the next week. Bring spare brake pads too, if it is wet you'll go through them pretty quick.I'm bummed I'm not doing this ride in 2012... ah well.
Word of warning, if wet.... First race stage, the last 5km is littered with lakes in the middle of the road. Going around is slower, take the plunge, put a snorkel on and get your butt behind the saddle and ride through 'em! It is thrilling to know whether or not you will make it through half wet or fully soaked in silty, red water!! Better still, sit behind some poor soul who is the guinea pig, if he/she falls in, take the 'other' line!!

Fav stages would be Granville Harbour, Montezuma falls (for its length).
