Race walker Brendan Boyce will be the last of the Donegal competitors to see Olympic action in Rio when he competes in the final of the Men's 50k walk on Friday.
Boyce's training partner and good friend Rob Heffernan carries Irish medal hopes going into the race.
But hopes are high that the Milford man can also maintain his recent good form and produce a fast time.
This will be Boyce's second appearance at an Olympic Games.
Four years ago, he got his first taste of an Olympic Games when competing in the 50km walk in London. He finished 29th in a time of 3 hours 55 minutes and 1 second. His time was a personal best and he would later be upgraded to 26th place following the disqualification of three Russian athletes.
Boyce and Heffernan became the first Irish athletes to qualify for the Rio Olympics when they achieved the qualifying standards racing in Slovakia in March of last year.
The Letterkenny AC member’s time of 3.48.56 was another personal best and knocked over six minutes off his time from London.
Tomorrow's race starts at 12 noon Irish time.
