Looking at the runners as they prepare to set off on a 48 hour endurance race, you can't help noticing their stubborn toughness as they face the less than promising weather conditions.

 NOTICE

The first few drops of rain have already begun to fall. But the runners seem quite unperturbed.

They set off in pairs in a staggered start, equipped with a tent, sleeping bag and essential food supplies, plus a map and compass.

In the next 48 hours they will be timed as they run over the steep hills and mountains around the valley.

 TIME

B8

They must navigate the course, and report at a series of pre-arranged check points before making it back to the starting point. It's a tough sport for tough people.

In some events the fell runner has to run up and down a specified number of peaks in a given time. This kind of race first began in 1932 when Bob Graham ran up and down 42 peaks in the Lake District in a single day.

That record has been beaten many times since then.

The current record of 77 peaks was set in 1997 by Mark Harfell. The women's record of 62 peaks belongs to Anne Stentiford.
