Jens Voigt is an amazing character...

Stage 16 he crashed on the first descent - then refused the sag wagon - he had no team car so they found him a bike ( a junior's bike with toe clips).  So he carried on with that until his team car could get to him and then jumped onto a new bike - caught up and finished the stage.  A lot worse for wear - but amazingly still upbeat and positive as always.

I think it's safe to say - he's tougher than you or I.

Here's the story in his words (including a photo of him riding the junior bike).
