The Wicklow Round is a long-distance hill running challenge in the Wicklow Mountains in Ireland. The route follows a proscribed 100-kilometre circuit of 26 mountains, which must be completed in a fixed order, that total over of elevation; there is some flexibility on route-choices between peaks. Rounds completed outside of a cut-off time of 24-hours are not generally recorded. Irish ultra-runner Joe Lalor is credited with the creation of the Round.
