Scilly42 : The Marathon

Scilly42 is a 42 km multi island trail marathon across the Isles of Scilly held in June and September 2027. The route takes runners around the full coast paths of St Martin’s, Tresco, Bryher and St Agnes before a final 5 km finish on St Mary’s. The event is limited to 150 participants and the entry fee is £210; entries for the listed dates are currently full and waiting lists are used if spaces become available.

The race combines coastal single track, rocky sections, sand and continuous undulation. Routes are professionally marked with bright orange flags and the wider event uses over 2000 flags across stages. Inter island movement is by boat with transitions timed to tidal conditions; the organiser operates two boats each holding 75 runners for Scilly60 and Scilly42. The race is self sufficient during stages: runners must carry their own kit for each stage and start with a minimum of 3 litres of water in their boat bag. Spare food, drink and clothing can be left on the boat or at the start line for use later in the day.

Cut offs are set to a pace of 8:30 min/km, providing a defined time window for the island stages; the final 5 km on St Mary’s has no cut off. Support is provided throughout and first aid cover is positioned at the start and finish of each island stage. Visit the organization's website for the most recent information.
