Ras Dewi Sant Marathon 2027: St Davids Cliff-Top 7-Mile Challenge

Ras Dewi Sant Marathon 2027 routes the ancient lanes and cliff-top arteries around St Davids, on the Pembrokeshire coast of southwest Wales. Beginning at the Bishops Palace beside St Davids Cathedral, the 7-mile course climbs the Cathedral Steps, threads quiet village roads, then unfurls along raw coastal escarpments to Porthgain before returning on the Pembrokeshire Coast Path. This fast, exposed route rewards runners with wild sea views and crisp Atlantic air, and it’s billed as a tough run with limited support.

What makes this event special is the immediate contrast between ecclesiastical stonework and jagged seaward geology: Ordovician and Cambrian rocks sculpt the headlands here, with slate and volcanic outcrops visible along the path. The Cathedral Steps provide a dramatic urban-to-wild transition; the Pembrokeshire Coast Path supplies continuous cliff-top panoramas, tiny coves and sea stacks. Expect gorse and coastal grassland underfoot, and seasonal seabirds wheeling offshore. The finish beneath St Davids’s medieval skyline is memorable—ancient architecture framing modern exertion.

Logistics are straightforward: meet at St Davids Cathedral at 08:00 for check-in. The event lists an 8-hour duration window, though most participants will aim for a compact effort in far less time—prepare for changeable weather and limited on-course aid. Entry is age 18+, group cap around 100 runners, and accessibility is limited; cancellation terms apply before 1 February 2027.

Plan for mixed surfaces: tarmac sections between the cathedral and coastline, then narrow, rocky trail on cliff edges. Shoes with good grip and a low drop are advisable; poles are uncommon but could help on descents. Lightweight waterproof layers, a race vest with essentials, and route knowledge or a map are important because marshals and support are sparse. Hydration and early nutrition strategies matter on this exposed coast.

Why book it? Beyond the race, Ras Dewi Sant is an invitation to discover a compact landscape of geological drama and maritime weather—one where local history is visible in stone and where finishing beneath Cathedral spires feels like a rite of passage. For visitors to Pembrokeshire, it’s both an athletic challenge and a shortcut to the best coastal scenery the national trail has to offer.

Start training on coastal trails to mimic the uneven footing and short, steep climbs of the Cathedral Steps; include tempo sessions and hill repeats, and practise running on hard, choppy rock underfoot. On event day, carry a minimal first-aid kit and blister supplies—self-sufficiency matters when aid is sparse. Nearby Porthgain offers a practical rendezvous for spectators and a classic post-run seafood stop, while St Davids has a handful of compact guesthouses and gear shops for last-minute needs. Bookings go through the event page; check cancellation cutoffs and pack for wind, rain, and sunshine in quick succession and comfortable footwear.
