The big race

Let’s suppose that Andrew and Charles run the 100 metres at a constant speed.
When Andrew crosses the finish line, Charles has run only 95 metres.
So Andrew wins the competition with a lead of 5 metres.
During a second competition, Andrew (who wants to make the competition more “balanced”) , penalizes himself voluntarily , starting 5 metres back the starting-line.
It is supposed that the two athletes run with the same speed they had during the first competition.
Who will win the second competition?
