About this race
The Castleknock 5k begins with a 1.5km downhill section from Castleknock College toward the Phoenix Park. The remainder of the course consists of a steady climb that leads by Farmleigh Estate. The race finishes in the centre of the village.
Course profile & record eligibility
World Athletics record-eligibility rules cap net elevation loss at 1m per km of race distance, and require the start and finish to be no more than 50% of the race distance apart — both meant to stop a course gaining an unfair edge from downhill grade or a point-to-point tailwind. This is based on this course's recorded elevation and GPS data, not an official measurement or certification.
