Fancy digging out your Halloween costume and getting out with the kids while supporting a great cause?
Well, here's your chance. The annual fun run in aid of the Children's Medical and Research Foundation (CMRF) will take place on Sunday at the Polo Grounds in Phoenix Park.
And to give the event that extra injection of fun, everyone taking part is being urged to dress in superhero costumes, with the grounds expected to be awash with Batmen, Supermen and Spider-Men.
Now in its third year, the run is a mere mile in length and even includes a toddler dash in order to get the little ones involved.
All proceeds raised from the day will go towards the CMRF, the fundraising arm of Crumlin Hospital.
An organiser said they are encouraging anyone interested in taking part to arrive at 9.30am for registration ahead of the race starting at 11.15am.
"It's a really fun, family day out and we got great numbers and support over the last few years. It's for a great cause and hopefully the weather will be on our side as well," she said.
Registration costs €25 for two adults and their children and it is €15 for an individual entry.
Funds raised from the day will go towards the renovation of the hospital's out-patients department, which sees more than 80,000 people a year. It will also help research into Cystic Fibrosis treatment.
