I should also admit to having ridden it in “tour” format last year – it was after that Ash offered me the timing gig.
It’s definitely at the Enduro-ey end of the spectrum. The riding is proper bonkers in places. Tight, tech, gnadgery, massively exposed. There’s also some amazingly fast flowy bits. Slightly different for me, as I “just” spent 6 days following Ash’s back wheel – but even the top pros said they went faster if they backed off the pace a little as the blind hairpins flowed faster, and there was less crashing.
Tips I picked up from last year – be happy carrying your bike for extended periods. Have shoes you’re happy walking in. (Day 2 on 2014 had a hike-a-bike section that lasted between 3 & 6 hours solid, depending on how quick you were – most people had forgiven Ash by the end of the end of the day) Oh, and read the maps. Carefully!!
