O'Sullivan claimed an Olympic 5000m silver medal in Sydney

O'Sullivan will compete in the Great Ireland Run on 15 April in Dublin.

"It's going to be my final good hard race as an elite athlete in Ireland. I'd like people to come and join me for the start of this last lap," she said.

The 37-year-old does plan to run other races this year and may even attempt to earn a place in the European Cross Country Championship in December.

Earlier, there were reports that the Great Ireland Run would be O'Sullivan's final competitive race.

These reports followed a press release sent to Dublin newsrooms but it now seems clear that O'Sullivan will continue to race during the remainder of 2007.

The former World and European Champion may compete on the track in the Cork City Sports in July while there have been suggestions that she might bow out after making a final international appearance at the European Cross Country Championships in Spain.

The only certainty is that O'Sullivan will run the 15 April race in Dublin.

"People have supported me along the way throughout the years and it would be nice to feel that they would also be a part of this final race for me (in Ireland)." O'Sullivan added.
