How does the TdF work?
I mean, could BW have been 'caught up' on the last day by anyone?
Is it based on shortest cumulative time over each stage?
Yes, it is the quickest over all time, you don't need to win every stage... In fact theoretically, you could win without winning any stage at all, but obviously you would have to be consistently near the front of the Peleton when nobody else was.
And yes, Wiggo would have had to have had a major accident for anyone to catch him but it could have happened.
He was something like 2.05 mins ahead of Froome in second place as it was.
.....That was a question and not something off the show was it?
