Race Info
The Jersey Marathon runs each October in St Helier, the capital of Jersey in the Channel Islands. The course starts and finishes at Weighbridge Place, heading west into Waterworks Valley before crossing the island's north and west parishes through St Ouen and St Brelade. Runners can also enter as a two- or five-person relay team covering the full course, or run the one-mile Marathon Mile. Kenya's Nathan Kioko holds the men's course record at 2:16:03 from 2023, and Alice Braham set the women's record of 2:40:47 in 2025.
