Bit of niche interest but if you use Memory Map (or some other map/gps utils) then this is a "qct" file of Le Mans and around the circuit in French IGN 1:25K. Might be useful if you were wandering about away from the normal roads etc.
If you have the proper memory Map app then you need the "Import Maps" license to use. Works out of the box with "MMTracker" on android. I haven't tried with other apps. Its a 20Mb file so you might want to be careful downloading via mobile.
