It is a punishing schedule. The Tour begins in Liege on June 30 and finishes on July 22. He would ride for gold in the road time-trial on Aug 1, with qualifying in the team pursuit — an event in which Wiggins won gold in Beijing — beginning in the velodrome on Aug 2.
As Britain’s road time-trial participant, Wiggins would also be required to compete in the road race, which takes place on July 28.
If Wiggo rides a full TdF, the Olympic road race, the ITT,
and the the team pursuit, it could go two ways.
He gives it his all in the road events, and ends up "overcooked" on the track, which could cost the pursuit team quite dearly. The worst case scenario of the pursuit team failing to make the knock-out stage will cause a bigger shitstorm than the 2008 Madison race ever did.
Or...
He slightly underperforms on the road to save himself for the track - in which case he might just as well have not bothered with the road events.
It sounds like Wiggo's bruised ego is writing a cheque that could bounce come next summer.
