Ras Dewi Sant Half Marathon 2027: Cathedral Steps to the 39 Steps Coastal Run

Ras Dewi Sant Half Marathon 2027 launches from the Cathedral Steps in St Davids, Pembrokeshire, United Kingdom. The route starts beneath the Bell Tower, threads through lanes to the hamlet of Trelyddyd Fawr, climbs coastal hills, drops to the Pembrokeshire Coast Path, passes Porthclais, and finishes back at the Cathedral on top of the iconic 39 Steps. This is a coastal race that reads like a tour of the headland: sea-sculpted cliffs, open moor and pasture, and a cathedral town that claims Britain’s smallest city status.

On race day the wind off St Bride’s Bay shapes the experience. Key features include the Cathedral Steps and Bell Tower at the start, rolling rises through Trelyddyd Fawr, the exposed coastal path with its cliff-edge tread, and the Porthclais cove where limestone and shale cliffs frame the harbor. Runners will see typical Pembrokeshire flora—gorse and coastal grasses—and may spot seabirds working the thermals along the cliffs. The finish on the 39 Steps provides a dramatic urban return, an instantly memorable contrast to the wild coastline.

This event is special because it stitches the town’s historic core to the wider coastal landscape. St Davids Cathedral is an anchoring cultural landmark: pilgrims arrived here for centuries, and the city’s compact streets and cathedral square form a fitting bookend to an outward-bound coastal loop. The course’s mixture of road, singletrack, and coastal footpath keeps the challenge varied; hill climbs reward with broad sea views and fast descents.

Practical details: the posted meeting point is St Davids Cathedral with a start time around 08:45. The advertised duration is approximately 8 hours to accommodate walking participants and large groups—competitive runners will finish far sooner. Age limits begin at 18 and group capacity is large, so expect a festival atmosphere and possible bottlenecks on narrow sections. Bring waterproof layers, shoes with good traction for muddy and rocky path sections, and plan logistics for return to the cathedral square.

Why book it? If you want a route that combines cathedral heritage, maritime cliffs, and a community race vibe, Ras Dewi Sant Half Marathon 2027 delivers. It’s as much a coastal trek with a race number as it is a competitive event—perfect for runners who want to test themselves on uneven terrain while soaking in Pembrokeshire’s dramatic coastline and St Davids’ singular historic center.

Allow extra time for narrow lanes and pedestrians in the cathedral precinct. Public transport to St Davids is limited—plan a carpool or check bus schedules in advance. Carry a small first-aid kit, electrolytes and a buff for wind. If you’re racing, scout the coastal sections beforehand; if you’re there for views, pause at Porthclais to drink in the harbor before looping back to the city this season.
