No. It should be either "You have run a marathon" or "You ran a marathon".
The runner you are referring to is the man who ran 26.1 miles. It was after the battle of Marathon. Sadly we do not know the name of the man, however the legend is that after the victory in Marathon, a Greek solider ran from Marathon to Rome to proclaim the news. The second he arrived, he told the king, and promptly died.

The word marathon comes from Greece. After a war a man ran the 26 odd miles to deliver the message that they had won a war, he uttered the message and then collapsed and then died. In memory of this man a marathon is run the exact distance he ran.
The number of people who ran the Arizona half marathon in 2010 were roughly 7,800 people.
Pheidippides ran 150 miles from Marathon to Sparta, then another 22 miles to Athens.
