Where can I find race entry details for Ireland?
Follow the link from the race guide to the organiser or entry provider, where one is available. Check the entry deadline, eligibility and current availability there. A listed race date does not necessarily mean entries are still open.
Why has a race moved out of the upcoming calendar?
Once its listed dates have passed, a race moves to the past-editions view unless another upcoming edition is recorded. Cancelled events also leave the upcoming list. The race guide stays available, and the event returns when a new date is added.
