So I am considering doing the Tour du Mont Blanc right after the North Face Ultra-Trail du Mont Blanc in Aug/Sept 2012. I was planning on arriving in Chamonix on 1 Sept and setting off on the TMB on 3 Sept. I was thinking of arriving early to experience some of the atmosphere surrounding the event... but then only setting off on my trek after the event was over. So (a) is the atmosphere in Chamonix for the event worth the extra time? and (b) is it unrealistic to expect to set off on the TMB the day after the festivities around the event end? Thanks for your help!
