Usain Bolt deserves a gold medal for what he pulled this weekend -- hitting up 3 massive parties in one day ... and doing it in a style worthy of the Fastest Man on Earth.
Bolt went on a tear through Kingston, Jamaica on Saturday -- ending the night at the Fiction Fantasy nightclub bash where he booked up the entire VIP section for himself and his entourage.
Sources at the club tell TMZ Sports ... Bolt bought more than 20 bottles of champagne for everyone partying in VIP.
Our Kingston sources say Bolt started the day at Maiden Cay -- an off shore party, only accessible by boat. Hours later Boltfest moved to downtown Kingston at the Cabana City outdoor party ... and finally crossed the finish line at Fiction Fantasy.
By the way ... looks like Maiden Cay is Usain's spot. We found several pics of him partying there year after year.
