A 58-year-old runner from Portstewart ran four marathons over three successive days in February to raise funds for The Donkey Sanctuary.
Eugene Winters — or Oggie as he is known to fellow runners — ran his seventh, eighth, ninth and 10th marathons of 2016 for the charity.
He sponsored himself £5 a mile to raise funds for the donkeys in need, handing over a cheque for £520 afterwards.
Oggie has visited the Donkey Sanctuary in Templepatrick in Belfast since completing his challenge to show his support.
He was inspired by the charity’s Donkey Assisted Interaction work for children with additional needs.
The marathon runs are part of Oggie’s personal challenge to complete 200 marathons before he reaches 60.
The runs for the Donkey Sanctuary bring his marathon total up to 171.
“Oggie has achieved a fantastic goal, which is one I’m sure everyone will admire,” said Kirsty Christmas, the Donkey Santuary’s community fundraising manager.
“We appreciate his enthusiasm and accomplishments this year and all the money donated will allow us to continue caring for donkeys and mules in need. We are grateful for the donation and wish him luck for his future running challenges.”
The Donkey Sanctuary has centres in Belfast, Birmingham, Ivybridge, Leeds, Manchester and Sidmouth.
Founded by the late Dr Elisabeth Svendsen in 1969, the charity supports projects to alleviate the suffering of donkeys in 30 countries worldwide.
It has projects in Egypt, Ethiopia, India, Kenya and Mexico where donkey welfare is improved through community education and veterinary work.
