About the race
Scilly110 – The Ultimate is a single-day trail running event held on 15 June 2027 in Porth Mellon, United Kingdom. The race covers a total distance of 110 km over multiple islands in the Isles of Scilly.
The route is organised as six stages across five inhabited islands. Runners begin with a full circuit of St Mary’s, then cross by boat to St Martin’s, Tresco, Bryher, and St Agnes. On each island competitors complete a full circumnavigation and then repeat the circuit in the opposite direction before a final loop of St Mary’s to complete the total distance. The event uses professional route marking and organised inter-island transport.
Cut-off times are based on maintaining a pace of 7:30 min/km. Consistent forward progress is required to meet stage cut-offs.
Entry is restricted to Scilly60 finishers or to runners who can demonstrate equivalent experience in a minimum 100 km trail race; the organiser may request such evidence. The field is strictly limited to 40 runners. Registration for the 2027 event closes on 14 June 2027. Visit the organization's website for the most recent information.
