I was on the uphills. I'm not much good at descending so I got overtaken a bit on the downs (you could tell the roadies from the mtbers by that measure). The course was 14k long, and in our team we reckoned a 45 minute lap was a fast one, although some people were going faster.
Those clicks are totally inaudible when you're riding - the camera mount wasn't shimmed so it was quite sensitive to bike noise. I think it might have been the forks making that noise!
The course was significantly more technical than either of the other two big 24s, Sleepless in the Saddle and Mountain Mayhem, which do get a bit dull after a while. It's certainly at the limit of what I'd want to do if I was riding it solo. The first climb was probably the boring bit for most people, but since it was where I did all my overtaking I didn't mind it.
