Traffic - Thursday v Friday arrival

[DTB77]

Hi all. Heading to Le Mans for I think my 6th year in a row. Previous years I've always travelled down Thursday morning, generally hitting the long traffic queues in to Le Mans late afternoon. Last year was particularly horrific as we tried to be clever and go the long way round to Arnage but missed the turning and instead ended up coming past the main entrance from the north to Blue Nord camping...

Anyway, considering a change of plan this year due to other commitments and travelling down on the Friday morning instead, but worried the traffic may be even worse than the Thursday? Does anyone have any experience of whether traffic is any worse on either day, or is it just going to be rubbish whichever day I choose and I should just suck it up?

Camping Blue Nord once more (clearly don't like change!)

Thanks for the responses, all very helpful (albeit still in two minds which day to go...!)
