Superheroes, firefighters, doctors and nurses took to the start line with hundreds of runners this evening for a life-saving charity's runway run.

Organisers of the East Anglian Air Ambulance event spoke of their delight after more than 350 fundraisers took part in a 5km or 10km run, jog or walk at a second world war airfield in south Norfolk.

The event was the third time the charity had organised a runway run at the Norfolk Gliding Club headquarters at Tibenham, which received twice as many entries as last year.

The runway run is set to raise around �15,000 for the air ambulance charity, which needs to generate more than �4m a year to keep its helicopters in the skies.

This year's event saw the addition of a 10km route on the airfield and a number of runners embraced the 999 theme and dressed up for the run in sunny, blustery conditions.

Hannah Clay, fundraising manager for Norfolk, said the popularity of the run was growing.

'Our numbers have doubled on last year and people have come from all over East Anglia and we are really pleased with it. We have got quite a few past patients that are doing it to show their support and we have got some business support as well.'
