The outgoing president is a patron of the Sanctuary Runners group which is made up of Irish citizens, migrants, asylum seekers and refugees.
One runner, Monica Pumpkin, who is originally from Botswana, handed him and his wife yellow roses to thank him for his support during his presidency.
In a statement, President Higgins said that serving as president of Ireland was “a great privilege”.
“I would like to thank the people of Ireland for the warmth of reception which they gave to both Sabina and myself over the past 14 years,” he said.
“How valuable it was to be able to join with them in engaging with the issues, projects and ideas that will help us to achieve the best of our country and the best representation of Ireland and its values abroad – an inclusive citizenship and a creative society in a real Republic.”
Earlier, a portrait of President Higgins was taken down from its central position inside the main entrance door to Leinster House.
Incoming president Catherine Connolly will be inaugurated at a ceremony in Dublin Castle on Tuesday.
