So, if you're sitting at your desk with a toothache today, maybe just be glad you don't have to go run a marathon as well.
Since completing his "triple triple", Bolt has been enjoying the London night-life, reportedly getting women to show their boobs by promising to let them fondle his gongs.
Earlier this week the triple Olympic champ invited clubbers to his hotel where some gave him and a pal a flash.
The Sun reports Bolt then made them stand as if on a podium, took his 100m, 200m and relay golds from a bag and laid them on a table.
Finally, he "awarded" each of them a medal.
When one girl asked who had come first, he joked: "It's all gold. There are no losers."
A source said: "Usain had been partying at Tape nightclub and was in a really cheeky mood.
"At first everyone was just goofing around but he started complimenting some of the ladies on their cleavage and encouraged two to flash him and a pal.
"Then he dished out his medals while music played from his iPhone. He was laughing a lot, pretending it was like Rio."
