Okay, it's after the event but...
www.radiolemans.com is always my first call for endurance races - they're providing coverage of all rounds of the WEC, in English, and there are always links to live streaming, lap data, etc. So far this year I've used them to follow the races at Dubai, Sebring, Spa, Nurburgring 24H, the Snetterton(!) 6-hours, and of course at the circuit for Le Mans this weekend. No doubt I'll be using their podcasts to re-live this years race in the coming weeks too, to catch all the bits I missed!
It's always worth checking the official Audi website, as they stream live footage for the races too, as did Peugeot last year.
All the best,
SB
