The Hurly Burly

29th September 2018: the fastest 10k you'll find: the Hurly Burly, an autumn 10k on the Mawddach in North Wales - with a run and a run-swim option.

The Bantham Swoosh

14th July 2018. The Bantham Swoosh is a 6km swim in a shallow, sandy-bottomed estuary. It's exciting, invigorating, beautiful and fun.
