The Two Castles Trails
Sudbury, United Kingdom • 4 May 2025
The Two Castles Trails is a unique trail running event featuring narrative races that guide participants through a circular route around Hedingham and Clare Castles. The marathon and half marathon routes are predominantly off-road, covering diverse terrains, and require runners to follow written instructions without marshals. Safety measures include running with a mobile phone registered at the event. Participants can expect well-stocked checkpoints, a cupless race format, and a medal along with hot food at the finish. The event is organized under the Trail Running Association's permit and encourages volunteer participation. Visit the organization's website for the most recent information.
