For the those that haven't left for the campsites yet...here are the timings for ITV's coverage in their Speed Sunday Le Mans Special progs.
(Note: This is for ITV London, subject to change etc etc etc)
Saturday 12th
14:40 - 15:30 ITV1
Sunday 13th
01:15 - 02:00 ITV1
13:30 - 15:30 ITV1
I.e. nearly 4 hours in total (which will be more like 2 when fast forwarding through the adverts
), but fair play to ITV for covering the race.
