About this race
Recognized as one of Ireland's fastest 5km routes, the Rathfarnham 5k follows a net downhill course designed for high-speed performance. Starting on Springfield Avenue, the route traverses Dodder View Road and Rathfarnham Road to Terenure Cross before returning via Templeogue Road to finish near Rathfarnham Bridge. The profile includes a significant 1.3km downhill closing segment, making it a primary destination for runners targeting personal bests.
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.
