Info drawn from Twitter & Facebook posts from John Kynaston again :

The LAP LENGTH for the course is 0.64 miles or 1.02 km – so in rough terms the Lap Count & KM distance is (more or less) the same (obviously the final distance in KM is going to be a little higher, an extra 1km per 50 laps)

At 5hrs the race leader is on 58 Laps (so just over 59km)
