Tour de France 2010

Was there a two up sprint, then a crash, rider first across line was relegated therefore second across line (with bike on shoulder) was awarded win? Or summink similar? Or was the rider so far ahead that when he had a mechanical he still had oodles of time to walk to the line?

Getting close.

Jean Alavoine run the last 10k's of stage 14 of the 1909 TDF with his bike over his shoulders to win the stage

That I had forgotten about, but wasn't the answer I was looking for.
