Ryder Hesjedal spent one day in pink at the Giro. Day one.
Despite his fine work helping Daniel Martin win Liege-Bastogne-Liege, Ryder Hesjedal will be a tad disappointed at how the first half of his year concluded.
The Canadian headed back to the Giro D'Italia as defending champion. Like Wiggins, he pulled out prior to Stage 13 after illness had took its toll during a grueling week's racing.
Hesjedal will at least console himself with plans for a crack at the upcoming Tour de France (and a new contract, as reported by CTV News). For Wiggins, there is less certainty about his future.
These two men are not the only former Grand Tour winners having a challenging season.
Andy Schleck endured a woeful 2012, and it has not been much better this time around.
The 2010 Tour de France winner missed last year's race after suffering injuries in the Criterium du Dauphine. Since then, Schleck has been grasping for any semblance of genuine fitness and form, only for it to escape him at almost every attempt.
Schleck will be hopeful his 25th place finish at the Tour of California will mark a turning point in his fortunes. The RadioShack-Leopard man has a further chance of resuscitating his 2013 at the Tour de Suisse.
The Luxembourg star's occasional rival, Alberto Contador, has not been as badly in the wars. The Spaniard finished on the podium at the Tour of Oman (second) and Tirreno-Adriatico (third), after all.
However, Contador's form at the Dauphine will have given many observers pause for thought.
A disastrous Stage Four individual time trial (he finished 3:37 down on winner Tony Martin) ended his overall hopes of success—though he blamed this poor showing on allergies.
More disconcerting was the way Chris Froome comprehensively caught, then blew past Contador on the way to winning the following day's stage.
Cadel Evans recorded a respectable third place at last month's Giro D'Italia.
Similar to Contador, the Australian's loss of time to eventual winner Vincenzo Nibali in the race's last week will have raised questions about the 2011 maillot jaune wearer's ability to perform against younger general classification rivals.
