David Gillick has admitted the ship may have “sailed” on his dream to run at the Olympic Games in London summer.
The double European 400m indoor gold medallist has been struggling with calf and hip injuries, and believes he will not have enough time to get into top shape before the Games begin next month.
He told RTÉ’s Kathryn Davis: “Unfortunately for me, I think the ship has sailed for the Olympics for David Gillick.
“It’s been a tough, really hard, couple of weeks, and unfortunately I have to accept where I’m at.
“I know my event inside out. I know what needs to be done in order to gain qualification and run fast times.
“Unfortunately, with injury, and also the timeframe, it looks as if my Olympic dream could be over.”
But the Dubliner is not planning on retiring any time soon, and feels he more to offer before he hands up his spikes.
“I love my sport. I want to continue for as long as I can. If I could run ‘til I’m 50, I’d do it,” Gillick said.
“Obviously, I have to take a bit of a break and reassess things because my body has got a little bit older and I’ve to accept that.
“But I’m looking at things positively. I’m looking to the future, and I still believe I’ve got a lot to give.”
Gillick, who turns 29 next month, is in Helsinki to compete in the 4x400m relay at the European Championships.
He said he is enjoying the team “environment” and feels the team has the ability to make the final.
“The craic is good, you know, I’m enjoying it,” Gillick said.
“There’s a good buzz in the team. A lot of the younger people are doing quite well at these championships; they’re grasping that opportunity and it’s creating a good buzz and it’s nice to be a part of that.”
He continued : “We’ve got a realistic shot of making the final. People are in good form. We’ve got Brian Gregan running well, Brian Murphy’s running well. We’ve got Tom Barr, in the hurdles, running well.
“So we’ve got a good little mix there. And I think if we can just get out there tomorrow and get in the mix with some of the good teams we can get pulled around for good times.”
