Usain Bolt 100m Rio Olympics Betting

Usain Bolt 100m Rio Olympics betting odds were coming in at -275 with Justin Gatlin offering up plenty of potential competition but at 3-1 odds. Either competitor offers solid value to win gold.

Bolt, who ranks 32nd of Forbes' list of the world's highest-paid athletes, has said Rio will be his final Olympics.

"Yes, this is the last Olympics for sure," the sprinter said. "I have done everything and have proven myself."

Bolt said he "really, really" wants to keep his world record in the 200 meters and said "it's going to take sub-19 [seconds]" to do so.

Bolt won three gold medals at both the 2008 Beijing and 2012 London Olympic Games.
