Cockroft thrilled to break record

British wheelchair racer Hannah Cockroft becomes the first athlete to break a world record in the Olympic Stadium in London and describes her achievement as 'incredible'.

The 19-year-old, who clocked a time of 18.56 secs in her T34 class in the 100m multi-classification race, says the Olympic Stadium is "amazing" and believes the track will suit wheelchair racers later this summer.
