With more than 22,500 people taking part in this year's Dublin Marathon, many participants are running for charitable causes.
Among them is 85-year-old Kevin Stynes who was presented with the Lord Mayor's Medal before the marathon, in recognition of his fundraising for Down Syndrome Ireland.
Mr Stynes, who was from Dublin, is taking part in his 42nd marathon in a row.
He told RTÉ News that he was "shocked and embarrassed" to receive the medal, "because I don't feel I deserve it".
Mr Stynes said that the honour was fantastic and a great way to finish his running career.
Sarah Jane McEntee headed up Team SJ, competing in the event with her sister Keelin McEntee who said that both the training and the race have been a great chance for them to bond.
"Our relationship has gotten much stronger," she said.
Her sister plays inspirational music including the Spice Girls as they take part.
They are raising money through the Inner City Running Club page for Rayne Judge, a four-year-old girl from Glasnevin, Dublin who has a rare form of cancer and is seeking urgent medical treatment abroad.
Gareth Winders is running his 20th marathon but his first with Cillian Kenn, who he coaches in basketball for the Shooting Stars All Inclusive Team.
They were excited about getting lots of support from the crowd.
Also taking part in the marathon is Eugene 'Oggie' Winters from Derry, who has been running multiple marathons for 'Pretty n Pink' and has already completed the Belfast Marathon this year, along with numerous other events.
Having started running in his 40s, he now competes every few weeks in running events.
