The Trident is an endurance event developed by former Special Forces Operators and Royal Marines Commandos, combining three disciplines to represent the prongs of the trident spear, to test both mental and physical resilience.

The course starts with a ship-to-shore sea swim of approximately 1.5km inland towards the Jurassic Coast. An assault style cliff run follows, where participants will be tasked to track distinctive landmarks across a 14km route with several ascents and descents and an elevation gain of 600 meters. The 30km cycle course starts with a demanding climb on to country roads notorious for sudden uphill climbs.

All funds raised will be donated to the SBSA whose clear commitment to all past, present and future Operators and their dependants ensures a lifetime of support where necessary.
