USUALLY it hums to the sound of screeching tyres and jet engines but this weekend the runway at Heathrow Airport will echo to the noise of running feet.
The northern runway at the airport is the setting for a Midnight Runway Run to be held on Saturday in aid of Marie Curie Cancer Care.
Around 120 runners are expected to take part in the event which will involve a 10-kilometre dash around the tarmac in the early hours and hopes to raise £24,000.
The runway normally handles around 650 flights a day and those taking part will be given priviledged views of the new Terminal 5 building, as well as the 89 metre high Air Traffic Control Tower.
Marie Curie Cancer Care is a UK charity that provides nursing, totally free of charge, to give terminally ill people the choice of dying at home.
It was voted by BAA Heathrow staff as Heathrow's first ever charity of the year and they are hoping to raise over £100,000 this year which will provide 5,000 hours of nursing care in the Heathrow area.
