The Roman Run Merthyr is an annual charity race that supports the Mayor of Merthyr Charity Appeal, offering runners a challenging course with scenic routes through historic landscapes. This year’s edition maintains its commitment to raising funds for important community causes while providing participants with an engaging and memorable experience. Set against the backdrop of Brecon and Merthyr Tydfil in Wales, the race covers a distance of 16.37 miles (26.35 kilometers) with approximately 2,015 feet (614 meters) of elevation gain. The terrain is varied and demanding, making it essential for runners to be well-prepared before registration. To ensure safety and manage the race efficiently, participants must adhere to a strict cutoff time of four hours and thirty minutes.

The designated pick-up point is Cyfarthfa Castle, Merthyr Tydfil, where runners should arrive by 9:30 AM on race day for a smooth transition. No changes can be made after July 31st regarding transportation options. Race numbers will be assigned and published online on August 28th, allowing participants to note their number ahead of the event. This measure streamlines the registration process at the start line, ensuring that everyone is ready to go come race day. The finish location at Cyfarthfa Castle serves as the hub for post-race activities and celebrations, providing a warm welcome to all runners who complete the challenging course. Weather conditions can vary significantly between Brecon and Merthyr Tydfil due to their different elevations and microclimates. Runners are advised to dress appropriately based on local weather forecasts leading up to the event day.
