An RAF reservist who works in Isleworth is taking part in the military's answer to the Tour de France.
Corporal Faye Hudson, a manager in BSkyB's intelligence and investigations department, is on a six-month detachment in Camp Bastion, Afghanistan.
The 35-year-old is joining comrades on the Tour de Herrick, named after the military operation in the country, during which they will cover the same distance as riders in the Tour de France.
Each rider will complete a different stage of the tour, cycling up to 237.5 kilometres in a day, on an exercise bike at the camp.
Their tour, running concurrently with the real thing, from July 5 to 27, is being held to raise money for War Child, which protects children caught up in conflicts across the world.
Ms Hudson, who lives in Wendover, Buckinghamshire, serves with No 3 (Tactical) Police Squadron Police Reserves at RAF Henlow, in Bedfordshire.
In Afghanistan, she is part of 'Team MEP' - a group of army officials working at the camp's main entry point, where they process the daily entrance and departure of local workers.
"We are all of different abilities but have one purpose; to complete each stage and raise as much money as we can whilst keeping operations running smoothly," she said.
"Whilst actively serving out here, this is something we are excited to get involved with. Not only will it give us focus and create a real team spirit, but most importantly it is a really worthwhile charity to get involved with and help those less fortunate than ourselves."
