Reid weighing up Tokyo
Aileen Reid hasn't ruled out another Olympics after a satisfactory performance saw her finish 21st in the women's triathlon.
The 34-year-old was pleased with her Saturday showing, an improvement on the London 2012 Games where a bike crash saw her finish in the lower half of competitors.
"I put it all out there. I left everything that I had," she said on RTÉ.
"It was a wee bit tactical in the run but I felt like I did the best job I could do to give myself the best chance for a good finish.
"On the bike, I could put my hand up and say I put in the work. I was leading my group up and down the hill each time.
"In a race like that, you are in danger of almost killing yourself in the first half and not having enough energy to swim well."
The Derry woman lost time on the 40km cycling stage having been 18 seconds behind the race leader coming out of the water.
She eventually finished four minutes and 58 seconds behind United States' Gwen Jorgensen, who dethroned 2012's champion, Nicola Spirig from Switzerland.
Reid had hinted at the Commonwealth Games that she would hang up her running shoes following the Rio Olympics.
However, she refused to rule out Tokyo 2020 when reflecting on winner Spirig who has continued to compete after the birth of her first child.
"There's now more girls racing on the circuit that have kids," she said. "It doesn't seem to have done Nicola any harm and some of the other girls too, so never say never."
