Event overview

This event is a staple in the off-road events calendar. Formerly known as XTERRA Matterley, it’s now back where it began, with TrailX. As well as the full distance race we offer a Youth and HalfX event so if you’re at least 14 years old on race day and have sense for adventure come join us, regardless of your experience! The full distance competition consists of 5km of trail running, a 15km cross country mountain bike ride, and finally a 2.5km run to finish. If you’re joining us for the HalfX or the Youth race then it’s the same format of run, ride, run but the trail running route will be 2.5km and the mountain biking will be around 10km.

4 steps to wellbeing
Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
