The Tunnel Marathon Take 2

The Tunnel Marathon Take 2 is set to be the UK's first fully underground marathon, taking place at the UCAP Bunker, a historic site used by the Royal Navy during World War II. This unique event offers runners the chance to experience a marathon in a distinctive environment, featuring several tunnels that require participants to navigate sections with low ceilings. The marathon aims to replicate the experience of the kristalmarathon held in Germany.

Participants are required to wear headtorches and cycle helmets for safety. The event is organized by Sussex Trail Events, with entries opening in January 2025. Visit the organization's website for the most recent information.
