A Birmingham man is running this year's Albert Bartlett Edinburgh Marathon in aid of The Donkey Sanctuary, based near Sidmouth in Devon.
Sean Conboy, from Great Barr, is a keen runner and was inspired to take on the challenge having seen the plight of so many donkeys, particularly when travelling around Asia and Central America.
He says: "I have seen some donkeys in appalling condition, and have given a donkey my last water whilst hiking in Nepal because he looked so weak and dehydrated - bearing things like this in mind, I decided to do whatever I could ease some of the pain and suffering they have had to endure."
Sean is a member of Birchfield Harrier's Running Club and hopes fellow runners, family, friends and work colleagues will help him raise the minimum sponsorship of £500 for The Donkey Sanctuary.
He says "I previously raised £1,000 for Age Concern when I ran the Dublin Marathon and would love to get a similar amount this time. People could help me by visiting my Justgiving website and pledging just a small amount."
The funds raised by Sean will be put towards the charity's new Sanctuary from Suffering campaign, which launches at the end of February. This aims to improve people's awareness of the Sanctuary's work in developing countries and help ease the suffering of working donkeys.
The Donkey Sanctuary's international work includes regular mobile veterinary clinics held in Egypt, Ethiopia, India, Kenya and Mexico; the charity makes no charge for its services.
Dawn Vincent, The Donkey Sanctuary's press officer, says: "We are extremely grateful to Sean for running the marathon in aid of our Sanctuary from Suffering campaign.
"Our teams work extremely hard to give the donkeys a better life and receive expert veterinary care. They also work closely with the owners to help them understand more about their donkey’s needs. These projects provide Sanctuary from Suffering to working donkeys, and are funded entirely by donations."
