Scilly Swim Challenge 1-Day

The Scilly Swim Challenge 1-Day edition covers a 15km total distance across the Isles of Scilly, requiring swimmers to navigate five distinct sea crossings between islands. Scheduled for September 20, 2026, the event is organized by Level Water, with an entry fee of £149.50. Swimmers encounter a landscape shaped by maritime history, where the water is often bordered by thickets of tamarisk shrubs that define the island's coastal character.

Historical currents and landmarks

As you navigate the waters, you are tracing routes marked by significant maritime events. Near the rocky outcrops, you may pass the site where the steam-packet Thames met its end on January 4, 1841. This disaster, occurring during a severe westerly gale, claimed 57 lives and remains one of the most sobering reminders of the power of these seas, eventually leading to the awarding of the RNIPLS Gold Medal to Captain Charles Steel. Further along the course, the silhouette of the Star Castle fortress, constructed in 1593, offers a constant navigational reference point. Designed as an eight-pointed star to defend against potential Spanish incursions, its position on the Garrison remains a commanding feature of the St Mary's skyline.

Traditions in the water

Swimming in these channels requires respecting the same elements that dictated local survival for centuries. On February 13, 1833, Midshipman Baldwin Arden Wake demonstrated this necessity when the HMS Forrester was driven onto the Crow Bar. During a hurricane, he performed a life-saving swim through the storm with a line, a feat that earned him the RNIPLS Silver Medal and highlights the historical intensity of these currents. Today, the local water culture is centered around St Mary's Pool, a natural bay north of Hugh Town. This stretch of water, which you will traverse, is the training ground for teams participating in the World Pilot Gig Championships. The proximity to these historic channels and active maritime hubs ensures that the 15km route remains a direct connection to the legacy of the archipelago.
