Simbine today starts his campaign at the IAAF World Championships in Doha backing into the blocks in the 100m heats.
The 26-year-old has featured in the 100m final at both the Rio 2016 Olympic Games and the 2017 London World Championships where he finished fifth in each race.
“I wouldn’t say I am desperate to upgrade to a podium spot, I worked my way up to a podium spot,” Simbine said.
“I am in the mindset of where I am a stronger runner, I am a more mature runner, and I can handle myself in high-pressure situations. It is now for me to go out and do what I know I can do.”
