The Paralympic gold medalist who smashed his own 200m world record at the London 2012 Games says the race went perfectly to plan.

In front of the roaring home crowd, the popular 36-year-old from Nottingham, a double above-the-knee amputee, ran 24.38 seconds to win the T42 category title by a huge margin.

In the final 100m, he came through the pack to a huge winning margin that saw him break his own world record time of 24.93 seconds.

Whitehead, who has made the step down from marathon running to the 200m sprint, said: "That is all the stamina coming in from my marathon days coming into play there.

"For me it is about a process of getting into a situation of control and then to win.

"I have got four phases of my race - get going, a gliding phase and then when I get to 120 metres I really push on and then I am trying to hold that cadence all the way through to the finish."

In 2009 he became the first leg amputee to run under three hours for the marathon.
