Tens of thousands are expected to run, walk or jog the Flora Women's Mini Marathon in Dublin today.
The 10k gets underway at 2 o'clock this afternoon.
Last year around 40-thousand turned out, raising more than 12 million Euro for 700 different charities.
Among those taking part this year is Aideen Finnegan from the Dublin News Centre.

A number of road closures will be in place around Dublin City centre until 6 o'clock this evening to facilitate the mini marathon, which begins at 2pm on Baggot Street lower.
Zita Philpott of AA Roadwatch has the details:
