The Great Railway Run is a charity running event organised by the Carrigaline & District Lions Club with the support of Carrigaline Road Runners AC. The event features 5K, 10K and 25K distance options to accommodate as wide a range of participants as possible and takes place along the route of the old railway line from Cork city to Carrigaline. The predominantly flat route passes through Blackrock, Mahon, Rochestown, Passage, Monkstown, Raffeen and Shanbally before finally chugging into Carrigaline. This event has been moved from November to May to assist runners who are preparing for Cork City Marathon. The 25K is an ideal event to test pace and fitness exactly one month before the marathon.
