British Olympic sprinter Reece Prescod admitted he turned up at trials for the Tokyo Olympics overweight after gorging on takeout and playing hours of Call of Duty.

Prescod finished a disappointing fifth at the British trials last month, capping a turbulent year which saw him relocate to a US training base before returning just two months later.

The 25-year-old only made it into Great Britain's team for Tokyo by virtue of a discretionary pick by the UK Athletics head coach Christian Malcolm.

"It was weird when I was running in the trials," Prescod told reporters in Japan, per The Guardian. "I was well overweight and I got absolutely whooshed, absolutely battered."

The Brit said he weighed 86 kilograms at the trials - 8 kilos more than his usual race weight.

"I don't know if it was American food or if I love Deliveroo too much," added the European silver medalist. Deliveroo is a popular British takeaway service similar to DoorDash.

"Where I live by Canary Wharf you've got Joe And The Juice in the morning, Pret, then you come back for lunch time, there's a Nando's, there's GBK [Gourmet Burger Kitchen].

"One of my close friends as well and her family have an amazing Caribbean restaurant, so I could just do that.

"Then I jump on Call of Duty with the boys, and then we're eating, a little snack break, and instead of having a fruit salad, I might order from Cake and Custard Factory.

"Before you know it, it's a jam tart, a pink icing cake with some custard, and then I've ordered two and an Appletiser and then I go to bed. You do that for a week and the weight just ends up going on."

Prescod, who ran a career best wind-assisted 9.88 in 2018, says he has since ditched the unhealthy diet and Call of Duty sessions in the hopes of winning a medal in Tokyo.

"This holding camp I need to stick to the fruit salads and the water, chicken and ease up a little bit," he said. "There will be no Cake and Custard Factory and all that stuff. It's not good."

He added: "If I win a medal or do well, you will see me at the dessert bar, definitely."
