This year's Dublin City Marathon is underway.
Competitors are still pouring across the start line at Fitzwilliam Place.
11,000 Irish athletes are hitting the streets, with over 4,000 over seas competitors attending the marathon.
Cork Athlete Sonia O'Sullivan won the marathon 15 years ago.
She'll be competing again today to raise money for the Irish Guide Dogs.
Her top tip is to start off slow.
