Did the bike last year & doing it again this year & as others have said it's a course that has a bit of everything; some short, sharp out of the saddle climbs, some longer slow climbs, some undulating sections & some nice flats / descents where you can get the speed up!
Definitely agree though not to push it too much on the first or those hills will bite on the second. I was only doing relay last year (and unfortuantely again this year; damn injuries!) but because I thought I'd do my bit for the team I went like a bat out of hell right from the start so was really hurting the last 10-15 miles & consequently saw my breakfast again when I stopped, so will definitely be pacing myself a bit better this year!!
With regards to speeding / tricky bits, the race briefing on the Saturday morning does cover this quite well & specific areas to watch out for, but def agree with the drafting comment as they popped up at random places all over the course!
