The famous Le Mans 24 hour road race takes place 15 – 16 June 2019 – so steer clear of Le Mans (72 Sarthe, Pays de la Loire) for the weekend (and a few days beforehand) unless you are a motor-racing enthusiast. Admittedly things are much easier now with the A28 autoroute taking you north-south from the Channel coast and Alencon down towards Niort and the south west without entering the Le Mans itself, but traffic will be heavy – often with some wonderful classic cars to admire en-route.

The French Motorcycle Grand Prix takes over Le Mans and the circuit 17 – 19 May 2o19 (Moto GP de France)
When the town is not full of racing enthusiasts, it is well worth a visit with a fine old medieval city centre to explore – see www.lemanstourisme.com
From 2010 – The Le Mans 24 Hours:
The 78th running of the greatest endurance race in the world will take place on the big 13,629-km circuit, which also uses part of the Bugatti layout (built in 1966), and a section of the main Le Mans-Tours road closed to traffic for the event.
On this layout, the record for the greatest distance covered in the race is held by David Brabham, Marc Gené and Alexander Wurz, the 2009 winners; they covered 382 laps, a distance of 5.206,278 kms at an average speed of 216,664 km/h. Every year, the Le Mans 24 Hours attracts a big crowd, 234 800 spectators in 2009, for example.
