The countdown is on to the Dublin City Marathon.
25,000 people will take part in the event on Sunday which has become the fourth largest in Europe.
For some it's about a personal best, for most it's just about making it to the finishing line.
Months of hard training will be put to the test on Sunday when 25 thousand people run the 26.2 miles.
Runners are advised to pack their bags in advance, bring a throw away top for the start line and pace themselves.
Marathon Coach Brendan Hackett also has this major tip.
"Toilet paper!"
"Just in case," he said.
Brendan says there will be plenty of porta loos "but it's always nice to have your own [loo roll]."
Northside DARTs
Anyone running or watching the marathon is advised that no Northside DARTS are running this Bank Holiday Weekend because of engineering works.
Jane Cregan from Irish Rail admits it's not ideal.
Jane says they're "essential line maintenance works that have to be completed."
Irish Rail can organise a much longer closure at a bank holiday because the numbers travelling are down on weekdays.
"So this is why we've made the decision to do these works at this time."
The Marathon begins on Fitzwilliam Street Upper from 8.40 on Sunday and remain open for 7 hours to give everyone the chance to finish,
