By TP I was referring to the Trans Provence btw, but much the same craic really and I’ve ridden much of the Trans Sav trails area anyway.
Sounds like climbing shouldn’t be a problem then! The trails are amazing, and quite long usually, as you might expect.
I rode a couple of the stages of the 2015 TransSav the week before the race (taped out and everything) and really the difference will depend on whether you want to “race” or just enjoy riding it. One stage was basically the size of 3 good size UK descents, but between part 1 and 2 there was a quarter mile sprint through a fairly flat medow, and between 2 and 3 another Sprint on an undulating fire road. We were just riding normally, but we’d been going for like 15 or 20mins and we were still on stage!
Tech wise, if you enjoy big Lakes or Welsh stuff, Tweed valley off piste etc, you shouldn’t have much trouble, it is mostly flowy singletrack with varying amounts of switchbacks (normally lots), steeper bits, and rock.
