Nant yr Arian Silver Trail

Set in the Cambrian Mountains, Nant Yr Arian Silver Trail offers Half Marathon and 10k routes, with junior distances for younger runners (0.5 mile for under 7; 1.5 miles for 7–11; 2.6 miles for 12–16). The event is run by Aberystwyth Athletic Club as a not-for-profit, family-friendly affair with fully signed and waymarked courses and marshals. Courses traverse challenging, varied trail terrain with spectacular mountain scenery; GPX files available for backup.

Half Marathon includes two feed stations; 10k has one. Mandatory kit is recommended for weather; an inclusive village with hot/cold food, and optional hoodies/tees. No corporate feel, and sold-out status reflects strong community support. Visit the organization's website for the most recent information.
