Cancellara: Even Superman has a weak moment

Last year, Fabian Cancellara accelerated on the Kapelmuur in Geraardsbergen to drop Tom Boonen and ride off to win the Tour of Flanders in a solo. But in 2011, the Swiss rider suffered cramps on the famous climb and couldn't get away. The overwhelming favourite ended up in third place, losing the sprint of the three-man group which had formed at the end.
