At last found this, sorry for the delay:
Are there shuttles to get around inside the 24 Hours of Le Mans circuit?
A shuttle network is available free of charge for ticket holders.
The shuttles will operate starting on Wednesday 7 June between the North Gate and Mulsanne and Arnage Corners.
They are in service every day from 09:00 to 00:30 and non-stop on Saturday 10 to Sunday 11 June.
Be safe, have fun!
