About this race

The Jack Cox 10km is a road race held in Kilcormac, County Offaly, typically serving as the Offaly 10k Road Race Championships. The course is set in the countryside at the foot of the Slieve Bloom Mountains, starting and finishing near the Faithful Fields GAA center. It is characterized as a fast-paced, scenic route through local townlands, consisting of relatively level terrain with some undulations.

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.
