The 2021 KBC Dublin Marathon has been cancelled for the second year in a row, with organisers citing "too many unknowns" ahead of the 24 October event.
Last year's event was one of many sporting events cancelled due to the coronavirus pandemic and organisers did not feel it was advisable to hold such a large event with "recent updates on modelling around Covid-19".
Jim Aughney, Race Director, said: "It is with great regret that we are cancelling the KBC Dublin Marathon for the second year in a row.
Despite vigorous evaluations, there are still too many unknowns to be confident that we could provide a safe event given the pure scale of the marathon. "We have a duty of care to the runners, volunteers, suppliers and supporters.
