eyes history in Rio Olympics

Usain Bolt eyes history against Gatlin after Michael Phelps heroics

A day after American swimmer Phelps brought the curtain down on his extraordinary career with a record 23rd gold medal, Bolt will attempt to complete the first leg of an unprecedented "triple-triple" in the 100m at the Olympic Stadium.

With semi-finals scheduled at 9pm local time (10am Monday AEST), Bolt is poised to line up for the final at around 10:25pm (11:25am AEST) where he will aim to clinch a third consecutive 100m crown after wins in 2008 and 2012.

The Jamaican superstar made his opening bow in Rio during Saturday's heats, coasting to victory in 10.07sec.
