Ring O’ Fire Ultra Marathon: 4-6 September 2026

Step into the extraordinary Ring O’ Fire, a non-stop, 130-mile endurance race that will take you on an incredible journey around the stunning Isle of Anglesey / Ynys Môn, North Wales.

Starting and finishing at Breakwater Country Park, Holyhead, runners will compete a full circumnavigation of the enigmatic island.

It has the words 'Anglesey' and 'Ynys Môn' on it in white. Over lapping the right corner of this map is a circle with the Welsh flag on it.
