Take Part


Our events, have grown in popularity and expertise, and we owe this success largely to the amazing team of volunteers that kindly give up their time to help create an unforgettable experience!


How to get involved

We offer a Trading Places Scheme, whereby a free* race place, up to and including Olympic Distance Triathlon, is rewarded in return for a day’s volunteering with us. This role can be undertaken by yourself (the competitor), a friend, or a family member who would like to support you.

*The ‘Trading places’ entry fee in 2019 covers the cost of any event up to and including Olympic Distance Triathlon. For Gauntlet competitors, one day’s volunteering can gain you 50% off your race entry.

Requirement and responsibilities

The roles involved can be anything from assisting at registration to being out and about on the cycle route, cheering people on! We typically ask volunteers to arrive around 6am on the day that they are helping out, for a briefing and breakfast with an aim to be finished by 4/5pm (this can be earlier depending on event /circumstance). We are open to some leeway.
