Damien Parker, 39, was nearing the end of his morning run when the accident happened at the Ennis Road in Limerick.
The mourners in a packed St John’s Cathedral for his Requiem Mass were led by his widow, Tanya, and their five-year-old twins, Scott and Cerys.
Also attending were Mr Parker’s parents Mike and Ann, brothers Eddie, Michael and David, and sister, Suzanne.
An Post management were led by chief executive, Donal Connell, director of mail, Liam O’Sullivan, regional manager, John Martin and human resources manager, Pat Knight. Local management included Limerick delivery services manager, David Barry and area manager, Jack Dempsey.
Executive members of the Communications Workers Union present included Noel Ryan, chairman of the Limerick branch.
Up to 200 Limerick postal staff commenced work yesterday at 5am to enable them to complete the morning mail round before attending the Mass.
Fergal O’Grady, who played alongside Mr Parker at Fairview Rangers Football Club, said Damien, while small in stature, was huge in heart.
His soccer achievements, Mr O’Grady said, included winning an All Ireland schools medal with St Enda’s.
He recalled that after six years married to Tanya, their twin son and daughter were born.
“With the birth of the twins, he was overjoyed at long last being a complete family.
“He was a doting dad who loved on Sundays to wheel the twins in their buggy to the park.”
Mr O’Grady said those who worked with him at An Post regarded him as a likeable and kind colleague. “Since he joined An Post, he was a most popular member of staff, respected by his work colleagues and the people he delivered mail to.”
Mr Parker’s remains were taken for burial afterwards in Mount St Oliver Cemetery.
