As far as I see it the big three are push this thing further than most rider's would even give it a crack for. Wiggins, Cancellara and Martin would all beat the current record. I'm not sure Martin would prepare himself to have a go at it though. I think it'll be Cancellara having a go first once the spring classics are done and then we'll all get whipped into a frenzy by Wiggins having a pop in July to take everyone's mind off the TDF.
Mere mortals will not have a go once Wiggins has done his thing and we'll not hear about it until Martin has a few more years on the road and decide's now's the time (2020 anyone?).
