New for 2026, Storm The Castle duathlon will be based entirely within Ludlow’s historic medieval castle grounds, after previously being split between the castle and the rugby club.
For the first time, every stage of this legendary duathlon starts and finishes within the castle walls and surrounding grounds, creating an unforgettable race atmosphere. With two distances plus Junior Storm for under-13s, it’s open to all abilities. The setting, the challenge, and the crowd energy will make the 2026 event truly special.
Make Storm The Castle part of your 2026 race calendar.

Traditionally, this has always been a tough 48km distance duathlon. In 2023 we introduced a 30km Sprint Course, which has proved very popular.
Full Storm: approx. 10km run, 33km bike, 5km run format,
Sprint Storm: approx. 5km run, 23km bike and 2.5km,
The Radnor Rascal Junior Storm 1km fun run remains an integral high point of this event. Junior Stormers must be 13 years and under with those 10 years and under being accompanied by an adult.
