The schedule I'm seeing might be localized, but it says the whole race is on Eurosport 1. Not much else going on besides some cycling (so no Carlton Kirby?) which is on Eurosport 2 and British Superbikes, which will be shown delayed on Sunday.
Or "whole" race rather because every couple of hours there is a 10-minute "Le Mans Studio" segment.
