If you take Usain Bolt at his word, the Jamaican superstar will likely run his last Olympic race Friday night as he competes in the 4x100-meter relay.

Bolt, who has won two gold medals already – for the 100-meter sprint and the 200-meter sprint – has said that the 2016 Rio Olympics is his last.

The Jamaican team is favored to win the race, and if they do, the medal Bolt gets will be the ninth in his Olympic career.

The 4x100-meter relay is set to start at 9:35 p.m. live on NBC.
