Pembrokeshire's stunning coastline provides the perfect backdrop for runners of all levels at the Pembrokeshire Half Marathon and 10k, set to take place on September 26, 2027. This intimate race weekend offers two distances across undulating country roads that wind through picturesque villages and along dramatic clifftops. The event begins in Dale, a quaint village nestled within the Pembrokeshire Coast National Park. Both races start from here but diverge slightly after the initial kilometers: the 10k heads out to St Ann's Head before returning via sweeping coastal views of Milford Haven Waterway and Skokholm Island; while the Half Marathon continues further, taking runners on a loop around Marloes Peninsula with its additional hills. Both routes pass two historic lighthouses — one still active and another now converted into holiday accommodation. Participants can look forward to scenic vistas at every turn as they navigate quiet lanes that challenge even experienced racers. Water stations are strategically placed along the route, ensuring runners stay hydrated throughout their journey. The race finishes in front of the Boathouse Café, where a well-deserved Welsh cake awaits each finisher. This year's event continues its tradition of supporting local causes by raising funds for Greenacres Animal Rescue based nearby in Talbenny. Race-day parking is managed by dedicated volunteers from this charity who also collect donations on site. With only 300 spots available, the race sells out quickly and attracts a close-knit community of runners eager to experience Pembrokeshire's unique coastal challenge. Entries are capped at 15+ for the 10k and 17+ for the Half Marathon with no entry permitted on race day. Runners who enter early can secure their free organic cotton event t-shirt from Howies, guaranteed if they register by September 9th, 2027. Prizes are awarded across age categories, complemented by a special "Dale Frog" trophy for the first local finisher in the Half Marathon. For those interested in volunteering or marshalling, opportunities abound to contribute to this cherished community event. Detailed course maps and specific start times will be released closer to race day via Pembrokeshire Triathlon Club’s website. Runners can expect a fully-supported route with medical cover throughout and strict adherence to UK Athletics rules for safety. No headphones are allowed during the race, except bone-conduction models that do not impair hearing of traffic or marshals. Registration closes on September 15th, 2027, so interested participants should act quickly to secure their spot in this unforgettable coastal challenge.
