The 100k in 30 days challenge has taken off in a massive way, raising around €1.3 million for Breast Cancer Ireland.
Last year, Mairead met Louth man Niall O'Carroll who started the event after his family was impacted by a cancer diagnosis. Within 3 weeks of launching it, they had 15,000 people walking over 1 million kilometres and raising an incredible amount of money.
As the Pink Army sets off for another year, Mairead spoke to Niall's wife, Cara McAdam who inspired their journey.
If you want to take part in 100k in 30 days, it couldn't be easier. Head to their website where you can still register and catch up and then get out and about, walking running or wheeling 100k across this month!
