555 - Isles of Scilly, 8 to 12 October 2027
The 555 is a multi-day trail running event held across five of the Isles of Scilly. It runs over five days with one event on each island: St Martin's, Tresco, Bryher, St Agnes and St Mary's. Island order may change because of weather.
Participants choose from three distance formats:
- Loops: one loop of each island.
- Half Marathon: roughly a half marathon on each island.
- Marathon: roughly a marathon on each island.
Distances are approximate and may be slightly longer than stated. Entrants may choose single days or the full five-day week and can change their chosen distance each day.
All participant tickets include daily boat transfers to and from each island; spectator boat travel is not included and is approximately £16 per day. Those who enter all five days receive a framed jigsaw map of the islands and free celebratory food at the after party. Cost information published for the week shows a weekly fee and a per-day option.
Event support includes a dry indoor start/finish area on each island with toilets, hot and cold water, and shelter. Courses are clearly marked with orange flags. There are no en route energy stations, but runners can access personal kit between loops. Visit the organization's website for the most recent information.
