The RB10K is the Richard Burton 10k, a 10-kilometre running race starting at Cwmavon Rugby Club at 11:00am. Event information indicates an early-November race day, with a setup intended for runners of all levels, not exclusively fast club runners.
The course is not presented as a flat dash. Race materials mention twists, turns, ascents, descents, challenging terrain, and stretches requiring determination. Organizers provide an interactive Google Maps route and a start-to-finish video for entrants to study the course before the start.
