About this race

The Sonia O'Sullivan Cobh 10 Mile follows a single-loop paved route that showcases the "GOAT’s" hometown, starting at the Great Island Community Centre and finishing spectacularly at the Sonia O’Sullivan statue by the waterfront. The course travels through quiet, picturesque country roads around Cobh. It features a series of long drags and steep descents. The proceeds with proceeds support Breakthrough Cancer Research and local youth athletics.

Course profile & record eligibility

★ World Athletics Certified — Downhill (-4.3 m/km)
Officially certified, but documented by World Athletics as a downhill course — not eligible for record ratification under this criterion.

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.

Loop Course type
65m limit 16.1m Start/finish drop
0.80km limit 8.0km Start/finish separation
Its own recorded data doesn't independently satisfy both criteria — its certified status isn't affected by this estimate either way.
