Rabbit Run Wales invites runners to explore one of Britain’s most breathtaking coastal areas, with races ranging from exhilarating trails through rolling hills and deep valleys in the 12K race, to more ambitious distances such as the Marathon (42.2K) and Ultra (65K). Nestled within the Merthyr Mawr Warren National Nature Reserve along South Wales' coast, this event offers a unique blend of natural beauty and challenging terrain. The 12K course features winding trails that weave through rolling hills and deep valleys, punctuated by river crossings. Runners will also have the chance to conquer the Big Dipper, an iconic sand dune rising above other parts of Wales. This ascent challenges runners' endurance and agility while providing stunning views along the way. The Marathon distance expands upon the scenic beauty witnessed in the 12K race but extends further along South Wales’ dramatic coastline. Participants can expect plunging cliffs, secluded coves, panoramic sea vistas, and rolling hills as they traverse this breathtaking route. Completing this year's lineup is a new addition: the Rabbit Run Relay. This team event divides the marathon course into five segments of varying lengths. Running partners can alternate legs or tackle different portions of challenging trails together, making it an exciting way to experience diverse landscapes while sharing the journey with friends and family. For those looking for more than just a race day adventure, on-site camping is available at Rabbit Run Wales, allowing participants to fully immerse themselves in South Wales’ natural beauty. Additionally, runners can unwind after their efforts by enjoying time in the Forest Sauna located within easy reach of finishing lines—a perfect way to relax amidst nature before heading home. Whether drawn by the allure of testing personal limits on demanding trails or captivated by encounters with local flora and fauna along scenic coastal routes, Rabbit Run Wales stands out as a destination for trail runners seeking both physical challenge and serene beauty. With options catering from casual weekend warriors eager to sample new terrains to serious athletes aiming at pushing their boundaries across challenging distances, this event promises an unforgettable adventure set against the backdrop of one Britain’s most spectacular natural settings. Rabbit Run Wales is not just about competitive racing; it's a celebration of trail running in its purest form. Offering everything from exhilarating single-day races to full weekend getaways rich with relaxation opportunities and immersion into stunning coastal vistas, this event caters to everyone looking for more than their daily run routine.
