In reply to Ndawson:
We were there for the last week of August last year (22nd-29th) and it was quite busy in town because of the UTMB. Then again, watching all the runners and browsing the trade expo was good fun.
France generally is quieter that last week, and the rental prices reflect that, but be warned that the weather may not be all that good. For most of the week it was great (brain-boiling hot at times) but I recall that on the Sunday/Monday it rained quite a lot.
On the Monday we were at the Emmoson dam (to look at the dino foot prints) and all day the weather was pretty cruddy. At the end when we walked back across the dam to get to the car there was a lightning strike that felt just a few metres away and you should have seen us run!
