350 people signed up as Sanctuary Runners to run in the humanitarian movement’s signature blue t-shirts.
The Sanctuary Runners initiative, founded in Cork in Jan 2018 by journalist, Graham Clifford, sees Irish residents, asylum seekers and refugees, running together every Saturday.
“For many of our runners the journey to the start line for this year’s race has been a very difficult one,” Mr Clifford said.
“Running enables people in very difficult circumstances to taste liberation and the Sanctuary Runner concept breaks down the barriers which exist between those in Direct Provision and the rest of us in wider Irish society.
"Ours is a running group of hope, of solidarity and of decency and we would be so grateful to the people of Cork if they could cheer us on this Sunday.”
