Take Part


Our events, now in their fifth year have grown in popularity and expertise, and we owe this success largely to the amazing team of volunteers that kindly give their time to help create an unforgettable event.


How to be involved

We offer a Trading Places volunteer scheme, whereby a free* race place up to the value of £80 (or £80 credit towards a longer race) is given in return for a day’s marshaling at any one of the Castle Triathlon Series events. This role can be undertaken by yourself (the competitor), a friend or family member who would like to support you.

*The ‘Trading places’ entry fee in 2018 has a value of up to £80 meaning that most of the entry prices are free.

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.

Sign Up Now!

We would love to have your help at one (or more!) of our events.
