About this race
The Offaly 5k Series Birr (hosted by Birr AC) is a single-loop road race that starts and finishes near the town of Birr, often beginning on Syngefield Road. The course navigates a circuit on paved local roads, typically concluding near Birr Rugby Club. The terrain features an undulating profile, notably including a challenging incline for approximately 700m around the 3.5km mark, followed by a downhill section toward the finish line.
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.
