The course is likely to be largely unchanged from last year, when it went down well with the riders, the course offers plenty of fast singletrack, a couple of stream crossings (aided by purpose built bridges), dismounts, off camber sections, some decent decent climbs and fast open sections.
I raced this last year and came a fantastic 36th place (out of 36 finishers...). It's probably the hardest 50 minutes I've ever spent on a bike but I'll be there again next Sunday to try to improve on last year's result.
Even if you're not a racer (and I'm not a racer!) it's a great introduction to bike racing, and would be worth going to just to watch and cheer everyone one. I'll be the one at the back on a mountain bike getting lapped.
