Are you a Fugitive? The Fugitive Half Iron Distance gives you the chance to make a run for it and escape, racing only against the clock to see if you will get caught before its too late. With only the fastest over the line, before the cut off, only becoming free to runaway with a bespoke finishers medal and the honour of being from captivity.

Relay teams must consist of THREE participants - one for each leg.

Test your navigation and strategy by entering one of the four off-road adventures we have organised. Using a waterproof 1:25,000 OS map which we provide, navigate trails and hills on foot and bike to collect as many check points as you can in the set time. You plan your own strategy and route, deciding how many CPs you want to visit and in what order. You will lose 1 point for each 30s you are late coming back. All checkpoints are worth 10 points each. Distance covered depends on how many checkpoints are visited, and depends entirely on your level of fitness, as well as your running/biking and map reading skills.

A swim surrounded with mountains, a bike course in the heart of the Snowdonia National Park and a run through an awesome slate quarry - we challenge you to find a more iconic race than the Pedalcover Slateman Triathlon.
