About the race

Round the Rock is a coastal trail event around Jersey with three distance options that share an anti-clockwise route and a common finish in St Helier. The event offers a full island lap and shorter coastal sections that follow cliffs, bays, headlands and trails.

Distances:

  • 48 miles Ultra lap of the island
  • 26.2 miles Marathon along the north, west and south coasts
  • 13.1 miles Half Marathon covering the west and south coasts

The route is marked at decision points and organisers provide checkpoints with simple, practical supplies. Navigation is supported by course markings and GPX files; runners are expected to load the route onto a phone or GPS device and to manage themselves between support points. Mandatory kit includes a minimum 1000 ml water capacity, trail shoes with suitable grip, a long-sleeved warm layer, a foil blanket or bivvy bag, a charged phone with What3Words, and a reusable cup or drinking vessel. The event is described as small and independent and relies on local volunteers and practical checkpoint support rather than elaborate infrastructure.
