Dublin sailor Annalise Murphy finished her third day in Rio in gold medal position after an impressive display.
The athlete, who sails out of Dun Laoghaire, narrowly missed out on a medal in the London Olympics in 2012.
However, with only four races to go she ended ahead last night.
She finished fifth and second respectively in her two races in the Laser Radial class.
Her family have travelled to Rio and have been tracking her progress on a laptop throughout the competition.
Meanwhile, swimmer Fiona Doyle's Olympic dreams have been dashed, despite an impressive display during her final race.
The 24-year-old, from Raheen, Co Limerick, failed to qualify for the 200m breaststroke semi-final yesterday.
She was in the lead up to the final 50 metres before she was pipped by Argentina's Julia Sebastian.
Despite her disappointment, she will stay in Rio and attend the closing ceremony after taking in the sights of the city with her family today, said friend Laurie Mannix.
"She's upset that she didn't make the final, but yesterday was a day that she came out and swam her best," she said.
"It was a great achievement to get to the Olympics, and overall it's been a positive experience for her.
Fiona's proud family, including her parents Cathy and Con and grandfather Michael Doyle (84), have been cheering her on.
