Event overview

Set in the stunning Gower Peninsula – the UK’s first Area of Outstanding Natural Beauty - and famous for its golden beaches, limestone cliffs, wild moors, ridges, and woodlands.

The basecamp is in the grounds of the historic Penrice Castle, with weekend camping options and the 100km challenge is a figure-of-eight route made up of west and east loops which take in the best of the Peninsula, its history and its varied, unique landscape. With 75km, 50km, Marathon, 25km and 10K challenge options, as well as a bar and entertainment at basecamp - this event will be the highlight of the season!

A big finish-line celebration awaits with an amazing sense of achievement and once the aches subside you’ll feel energised, up for more of life’s real challenges – and, maybe, personal horizons redefined.
