Everyone knew it was an ideal stage for a breakaway, and everyone wanted to try, so the very consensus made the breakaway almost impossible to form. It took 52km of hard racing for 8 riders to do so. The presence of Filippo Ganna, all 1m93 and 76 kilos of him, among wiry mountain specialists like Carretero, Conti, Hagen and Zardini – a heavyweight in the ring against so many flyweights – made for the textbook illustration of cycling’s genetic determinism. After all, for a rhinoceros to climb like a mountain goat, he would have to generate impossible amounts of power. In any case, in a world of increasing specialisation, the world time trial and pursuit champion (not to mention world record holder) can hardly be expected to compete against the climbers.
