Two-time World Championship bronze medallist Rushell Clayton and Malik James-King emerged victorious in the women’s and men’s 400m hurdles events, respectively, at the inaugural Jamaica Athletics Invitational at the National Stadium in Kingston on Saturday.

Clayton looked in excellent early season form, running 53.72, a world leading time and her fastest season opener, to take the win ahead of American Anna Cockrell (53.76) and Jamaica’s Shian Salmon (54.57).

Clayton also tried out a new running pattern with 14 steps between hurdles.

“It felt amazing. I tried my best and I know my coach will be happy with that so I look forward to my next race which is next Sunday,” she said after the race.

“These ladies are who I compete against all the time. It’s an amazing feeling to always line up and compete against the best in the world,” Clayton added.

The men’s race saw Malik James-King spring an upset with a personal best 48.39 to win ahead of World Championship silver medallist Kyron McMaster (49.00) and Jaheel Hyde (49.48).

“I have a lot more to work on so I’m just going to be going back to the drawing board and listening to my coach,” James-King said after the race.

“I was surprised with the time, honestly. I expected 48 but I didn’t know an exact time. 48.3 is a really good time,” he added.
