Castleknock 5K

The 2026 Castleknock 5km, sponsored by Nordan will take place on Sunday the 14th of June, at 11:00am.

Join us on Sunday 14th of June at 11 am.

The Castleknock 5 KM is back for its 12th year! Run entirely by volunteers, this fun and family-friendly event brings the local community together every year.

Every year, The Castleknock 5 KM gives back to the community by sharing its profits. Profits from the 2026 event will be shared between our chosen charity and local community group; St. Francis Hospice will receive 30% and 70% to support Metro Saint Brigids Athletic Club.

This wonderful local event really brings our community together. Join us in June and make this a fun day out for all the family to remember.

The under 16 entry will remain at €15 throughout.

The first 1000 online entries will receive a race t-shirt.
