Stage 20, Saturday 17 July, individual time trial, Libourne – Saint-Émilion 30.8km
This stage visits the village of Montagne, which will seem like a bad joke to the big-boned types who have grovelled through the Alps and Pyrenees. Since last year’s reversal at La Planche des Belles Filles the Tour has fallen back in love with time trials and this one is long enough to create a surprise or two. In theory the Tour will have gone through more than enough mountains since leaving Brittany to ensure that the strongest climber has ample margin to relax on this stage. But that’s far from certain – and therein lies the great fascination of this race.
