The course runs through parkland and includes rolling runnable hills, firm sand on a beach section, and a climb known locally as the Parkrun finish hill. A pedestrian footbridge called the Lady's Stairs crosses the road and railway and provides access to the beach; this section is highlighted as a technically awkward area. Marshals will be positioned at important turns and a turn on the beach will be clearly marked.
Entry is limited to 250 runners. Entry fees noted are €7 for seniors and €5 for over 65s and under 18s. Registration is online only; no entries are taken at the event. Mandatory kit is Level A basic, specifically a showerproof, windproof jacket, and runners must be able to carry required kit. Random kit checks may be carried out and absence of required items can lead to refusal of entry or disqualification.
