Each August a race is held on a circuit of Mont Blanc, roughly following the Tour du Mont Blanc route. In 2007 look out for the race on 24-26 August, starting and finishing in Chamonix. The course is 163km long and climbs more than 8,900m. The fastest competitors expect to run it in under 25 hours and there is a limit of 46 hours for everyone. Around 2,500 runners took part in 2006 - watching them fly by is a real spectacle and was remarked upon by some of our clients last year. Disruption to walkers should be minimal.
