Round the Rock

Round the Rock Ultra Marathon in Jersey is a challenging, self-sufficient coastal Ultra that threads a 47-mile anti-clockwise loop around the island, starting and finishing at the Steam Clock in St Helier. The route blends trail and road segments (St Catherine’s to Les Fontaines; Grosnez; Beauport; finish) with aid stations every 8–10 miles. It emphasizes a grassroots, cupless ethos, with strict kit checks, no pacers, and no outside assistance.

Runners must carry essential gear and navigate by signs, keeping the sea to their right on exposed cliff paths. A 12-hour limit and a 12:30 halfway cut-off shape day. Visit the organization's website for the most recent information.
