1.25pm - Golf
Both Leona Maguire and Stephanie Meadow have plenty of work to do after the opening round of the women's golf competition. World amateur number one Maguire signed for a three over par 74 on Wednesday after she teed off in the first group of the day. She gets her second round underway at 1.25pm. Meanwhile it was a poor day for Meadow, who carded a six over par 77 on her Rio bow. She tees off at 2.47pm on Thursday.
2.00pm - Modern Pentathlon
The modern pentathlon gets underway on Thursday, with fencing the first event to take place - before a swim, show jumping, and a combination of pistol shooting and cross country running. In the women's competition Ireland are represented by Natalya Coyle, who finished an impressive ninth in the event on her Olympics debut in London. Along with Arthur Lannigan O'Keefe she won gold in the mixed relay in the pentathlon World Cup in Florida in May. O'Keefe represents Ireland in the men's competition, and he is the current European champion. He gets underway at 6.30pm.
3.00pm - Triathalon
Brian Keane is Ireland's sole representative in the men's triathalon and is taking part in his first Olympic Games, but at 35-years-old the Corkman is the oldest athlete in the 56-strong field. Keane made it to Rio in the final qualification race - finishing 20th in Yokohama to secure his place as the 50th qualifier for the Games.
4.00pm - Athletics
Thursday afternoon will present a Rio rarity - an Irish athlete competing in an athletics final, and the opportunity to watch it take place at a reasonable time. Thomas Barr delivered a sensational performance in the 400m hurdles semi-finals in the early hours of Wednesday morning, beating his own Irish record with a time of 48.39 and qualifying as the third fastest of the eight athletes who progressed. Only the USA's Kerron Clement, who ran 48.26, and Jamaica's Annsert Whyte, who ran 48.32, qualified faster than the Waterford hurdler. Barr, whose preparation for the Games was hampered by injury, will benefit from an ideal draw on Thursday - he starts the race in lane four.
5.05pm - Sailing
Ireland have involvement in another medal race on Thursday, although there is no hope of Matthew McGovern and Ryan Seaton emulating Annalise Murphy's silver medal. Seaton and McGovern won their final race in the men's 49er event and sit in eighth position overall, and a good showing on Thursday can see them place as high as fifth position. The duo have been consistent throughout the competition and could have had their eyes on a podium place were it not for finishes of 19th and 20th in races 10 and 11.
