16k Run Hugh Town: Scenic Coastal Circuit of St. Mary's

Route Overview & Local Insights

This 16.1km coastal circuit of St Mary's is a runner's dream, offering a near-complete loop of the largest island in the Scillies. Starting from the bustling hub of Hugh Town, you'll tackle a dynamic mix of terrain that is predominantly paved but features enough undulation (150m ascent) to keep your heart rate up. The route treats you to the rugged beauty of the Peninnis Head cliffs, the sheltered tranquility of Pelistry Bay, and the sweeping sands of Porth Cressa. Expect a refreshing sea breeze and unobstructed views across the archipelago as you navigate the island's perimeter, making this a moderately challenging but visually spectacular long-distance effort.

Steeped in maritime history and ancient lore, running on St Mary's feels like stepping back in time. As you pass the Garrison, you're traversing 16th-century fortifications built to defend against the Spanish Armada, while the stretch near Porth Hellick Bay takes you past the Bronze Age "Entrance Graves." Local runners often recommend timing your circuit to catch the shifting tides, which dramatically change the appearance of the northern sounds between St Mary's and Tresco. Keep an eye out for Atlantic gray seals near the rocky outcrops and enjoy the unique microclimate that allows subtropical plants to flourish along the roadside throughout the year.
