ONE marathon around the capital is enough for most Londoners but three intrepid Fulham athletes have just completed 10 back to back - running 262 miles through the Jordanian desert.
Jamie Clarke, Rory Penn and Charlie Barrett, along with friend Johann Boost from Wimbledon, completed the 262-mile trek last week in just under 57 hours.
And to describe the slog as a pain in the backside is not just metaphorical. By the end, the runners' buttocks looked like pincushions as they ached from the numerous injections the adventure demanded.
The breathtaking views served as a distraction from the task early on, but the heat soon took its toll.
"Day two was hell," said Penn. "We were crawling by the end, legs completely spent with feet aching and thighs in agony. At least Jordan was beautiful."
Halfway into the week the group's appreciation for the sand and scenery began to wane, along with their health.
"I had a really tough 25-40km, and was in a pretty dark place where my right knee really gave me some grief," said Boost after day three. "The painkillers were losing potency by then."
One of the upsides to the challenge was the non-stop eating required to get through each day, as Barrett explained: "I sat in the ice box for 30 seconds after day four and just ate freeze-dried mash with beef bits, to go with three Pepperamis and two tins of tuna.
"I combined that with eight double-energy gels, homemade flapjacks and mum's delicious brownies."
On day five there was a much more sombre mood in the camp, leaving Clarke, previously capable of masking his agony, revealing the strains of the run.
"Injuries were plaguing the team, and by that stage I, for one, was feeling pretty broken," he added.
The team expected to finish the challenge last Friday, day six, but in the end had to get their trainers back on for a Saturday stagger.
Their reward at the end was an impressive £60,000 raised for Breast Cancer Research.
