Great Britain's Hannah Cockroft reveals pre-200m heat nerves

Great Britain's wheelchair sprinter Hannah Cockroft has admitted that she was "nervous" before today's 200m heat at the Olympic Stadium.

The 20-year-old gold medallist eased into tonight's final with a Paralympic record time of 33.20s.

"[The] 200m is my favourite event," Cockroft told Channel 4. "I was actually more nervous for this one than for the final."

Cockroft's compatriot Melissa Nicholls also qualified for the final after finishing fourth in her heat.
