Irish Olympian Jerry Kiernan has died at the age of 67.
A long-distance runner, the Listowel native represented Ireland at the 1984 Summer Olympics in Los Angeles where he finished ninth in the men's marathon.
He won the Dublin Marathon in 1982 and 1992 and was the seventh Irishman to run a sub-four-minute mile. He also won the national cross country title in 1984.
Kiernan would go on to coach a number of athletes including middle-distance runner Ciara Mageean.
Having represented Ireland on the biggest stage, Kiernan went on to work at RTÉ for many years as one of its most renowned pundits, covering the athletics, most notably on successive Olympic Games' television coverage.
President Michael D Higgins led the tributes.
He said: "The death of Jerry Kiernan, Olympian, sports commentator and athletics coach will have been heard with sadness by all those in the sports community and those who enjoyed his voice in commentary.
"His achievements in 1984, and his enduring coaching legacy will be long remembered."
Fellow Olympian Eamonn Coghlan said: "I'm totally gutted to hear this very sad news. RIP Jerry Kiernan - my great friend, training partner, athlete, coach & commentator. He'll be hugely missed."

In a statement, his club Clonliffe Harriers said: "It's with absolute shock that Clonliffe Harriers have to announce the very sad death last night of 1984 Olympian and Clonliffe Harriers life member Jerry Kiernan.
"He will be greatly missed by his family, club mates, athletes and the athletics family."
Kiernan's work on television was often acclaimed for offering huge insight and also engaging audiences which included keen sports fans as well as the casual viewer.
Cliona O'Leary, Deputy Head of TV Sport, RTÉ, said: "We are all devastated; Jerry brought so much passion, honesty, humour and warmth to our coverage across three decades of Olympics, National, European and World Athletics Championships and Cross-Country Championships, and to everything he did.
"He was a great friend as well as a superb analyst; he was so knowledgeable across so many subjects, and what really stood out was his interest in other people and his desire to see them be the best they could be.
"Jerry brought so much to every encounter; it is so hard to believe that we have lost such a force of nature.
"We are all so sad to have lost such a great friend and colleague in RTÉ Sport and we send our sincere sympathies to Jerry's family and loved ones we are thinking of them at this extremely difficult time."
