Pre-race speculation had centred almost exclusively on the battle between these two individuals: the former best Classics rider in the world against the future best Classics rider in the world. Sagan has spent the last 12 months and more slowly inching his tanks on to Cancellara’s lawn, and this season has seen neither give any quarter to the other. There was stalemate in Milan-San Remo before Cancellara struck in E3. Then Sagan took Ghent-Wevelgem.
The problem facing both riders as they hammered away from the disintegrating peloton was simple. Cancellara needed to drop Sagan, the superior sprinter. Sagan had to stay with Cancellara. The result would depend on who would succeed.
Up and over the Kwaremont, Sagan gave no more than a bike length and a half to Cancellara. The Swiss rider was stronger, but not by enough. Sagan’s resistance was bending, but not breaking.
But on the Paterberg, the balance of power between the two riders, which has been shifting imperceptibly towards the Slovak for so many months, suddenly swung violently back to Cancellara. As Cancellara progressed relentlessly up the 20 per cent slope, Sagan’s body language changed, and he got out of the saddle. Riding out of the saddle on a cobbled climb is poor technique, and it showed that he was at his limit. Students of cycling history will remember the battle between Cancellara and Boonen over the Muur van Geraardsbergen in the 2010 Tour of Flanders: Cancellara hammering relentlessly to the summit, Boonen climbing out of the saddle and visibly losing ground, along with the race.
A small gap appeared between Cancellara’s wheel and that of Sagan as they rounded the shallow left-hand bend halfway up the Paterberg. Then it grew. On one side of the gap: the winner of the Tour of Flanders. On the other: the also-rans. The immoveable object on Cancellara’s wheel had finally been shifted.
At the top of the Paterberg, as he turned left onto the concrete slabs of the Stooktestraat, Cancellara looked back, saw that gap, and clicked through his gears, visibly accelerating away. When Sagan got to the top, instead of focusing his attention on his greatest rival, he also looked back. His race was now based on defending second, not winning first.
Cancellara’s lead ballooned. Sagan was picked up by Jurgen Roelandts, the crafty last survivor of a late break, but the pair could make little impression on the Swiss rider. Off the descent, with 12 kilometres to go, Cancellara had 15 seconds’ lead. Two kilometres later it was 30 seconds. Into the final five kilometres, he’d moved over a minute clear.
