Whitehead , who won Paralympic gold at London 2012, stormed clear of the field to win in 23.03sec, breaking his world record by 0.43sec, and afterwards promised he could go faster.
“I’m heavy in training at the moment so 23.03 is fine,” Whitehead said. “The goal is to go to Rio and put a solid 22 in. I still wanted to lower that world record.”
Asked for the secret of his success, he said: “It’s the age-old ethics of working hard and having a great team around me. My coach Keith Antoine is underestimated, his skill set is something else. I’m looking forward to Rio but I am still looking ahead to London 2017 [world championships] as well.”
There was a second world record for a British athlete at the Queen Elizabeth Olympic Park as Libby Clegg ran 24.44 to win the T11 200m. “I am absolutely gobsmacked at how I have performed,” Clegg said. “I can’t believe it. I have been getting better and better with every race and I’m loving every minute of it so far.”
However, there was frustration for Britain’s legendary Paralympian David Weir, who could only finish third in the T54 1500m behind his old rival Marcel Hug from Switzerland. While Hug crossed the line in 3:19.73, Weir was 0.19sec back in third with another Briton Richard Chiassaro in second.
“I’ve still got five weeks to prepare for the Paralympics,” Weir said. “I’m still doing over 120 miles a week, with the track work it will be 150-160 miles a week so it is not bad going.”
Britain’s Jonnie Peacock was left also wanting more after his second place in the men’s T43/T44, 0.07sec behind the Jarryd Wallace of the US who held his form to win in 10.80sec.
“I should have run a better race than that.” Peacock said.
“I have changed huge things in my technique this year, it is a bit up and down at the moment but it will come. I just need a bit more racing in my legs. I haven’t won at the Anniversary Games yet but I haven’t lost a championship so hopefully I will carry that into Rio.”
