A solicitor who has been blind since childhood is hoping to complete Monday's Flora Mini Marathon in less than an hour.
Sinead Kane will have a co-runner to guide her through the course on the day.
The 29-year-old is running in aid of ChildVision, the National Education Centre for Blind Children.
"It's my second Flora Mini Marathon. The last time I did it was 12 years ago. I am hoping to run it in 55 minutes, or definitely under the hour," Sinead said.
She has been running with a coach in training for her own safety.
"I am running with Marion Lyons, an ex-international runner for Ireland, who has a lot of experience and has been giving me a lot of good tips."
Marion is affiliated to St Finbarr's running club in Cork, and Sinead has now joined the club herself and intends to keep running after the challenge.
Sinead said she doesn't predict any problems with the race. "I am totally in sync running with Marion."
She said that as an advocate for blind children, it was important to show that even if you have a limitation, anything was possible.
Sinead added that she is hoping to raise as much as possible for her charity.
ChildVision in the heart of Drumcondra, Dublin, provides educational opportunities for Ireland's blind and partially sighted children and young adults in a safe and nurturing environment. Through varied education programmes, its highly trained and committed staff ensure that all students are treated as individuals.
In March 2009, Sinead qualified as Ireland's first visually impaired, registered blind solicitor.
She has in the past tutored law to students with disabilities in UCC.
Sinead will be one of the 40,000 plus women taking part in Monday's event in the city.
There will be four water stations along the course and a refill station on the corner of St Stephen's Green if participants have a bottle with them and need a top-up.
