A vicar and nurse are hopping into the saddle next month to complete the long ride from Warsaw to Vilnius in aid of Marie Curie Cancer Care.
Geoff Price, vicar of St Mary's Church in Bedfont, is hoping to complete the 360-mile trip through Poland and Lithuania with his wife, Hope, who is a Marie Curie nurse.
"Marie Curie is a cause that's very close to both our hearts," said Mr Price, 61. "We're neither of us in the prime of life but we've been training hard this year and I reckon we're in good enough shape."
The couple will be travelling 60 miles each day in a group of around 40 cyclists.
But both say they expect to enjoy the journey as well as earning much-needed cash for the charity, which supports terminally-ill cancer patients in their own homes.
Mrs Price, 58, said: "I'm fairly confident that all the training we've done will be enough and hopefully it'll be an enjoyable experience."
After they have completed their trek the couple will visit relatives in Lithuania and stay with some nuns Mr Price knows from a previous visit.
The determined couple have already raised around £6,000, all of which will be used to support the seven Marie Curie Nurses working in Hounslow. But they are hoping more people will back their journey and donate even more money to the worthwhile cause.
Mrs Price, who has been a Marie Curie nurse for 24 years, said: "I find it a privilege to be able to work in the community caring for people who are nearing the end of their lives. It's so much more natural to die at home."
