About this race
The Cork BHAA Gas Networks Ireland 5k is held in the Blackrock area of Cork City. Due to ongoing Marina roadworks the race has been running on the Blackrock-Mahon Greenway, starting near the old Blackrock railway station off the Blackrock Road, following the former railway line towards Rochestown and finishing at the Blackrock Castle car park. Registration is at Cork Boat Club from 6:30pm, with the first 500 entrants receiving a free t-shirt. The course is flat on tarmac greenway and includes a visually impaired category.
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.
