The US track star, who has won 13 medals across his Olympic and World Championship appearances, will on Sunday run his second marathon when he competes on the Gold Coast.

“We told him ‘hey, you should go and break our older brother William’s record of 2:12:10,” he said.

“I told them that I was going to go to Australia and run faster than you both.”

“The first was hard,” he said.

“I’m used to running 1500m and 5000m was probably the most I could do.

“Hopefully I can run 2:11:30 which is A-standard for the Olympic and then we’ll see what happens in Atlanta for 2020 Olympic trials.”
