Siddal soldier Philip Baxter is taking part in the Nightrider 2013 which is a 100km bike ride around London on June 8.
It sets off from Alexandra Palace and covers a circular route and many famous landmarks.
He is raising funds for Breast Cancer Research and riding with the landlady of his local pub Penelope Bloodworth and it is a cause close to her heart as she has been in remission since 2007.
She runs The Wharf Inn, near Southam, Warwickshire, with husband Keith and that is also raising funds for the cause.
Sgt Baxter has been serving in the Army for 18 years and is currently based at 3 (UK) Division in Salisbury, Wiltshire.
“When I left Afghanistan I was posted to the Defence EOD Munitions and Search School in Kineton, Warwickshire, as an instructor where I have spent the last three years teaching IEDD/Electronic Countermeasures.”
His time in Afghanistan was not without drama and the Courier reported in 2009 how he and his colleagues formed a human chain to try and pull three pals away from the open tailgate of their airborne Chinook helicopter when it came under fire.
They managed to save one soldier but two others fell to their deaths.
Sgt Baxter has previously raised money for Help for Heroes, The Heart Foundation, The Hillsborough Disaster Appeal and Great Ormond Street Hospital.
