Our races are entirely organised and marshalled by volunteers from our club. As much as we love our athletes training and racing together, supporting the club is equally important. We do ask all LF

TC members to volunteer at our own club organised races throughout the year to make them a success. If you would like to help at any of the races, please email and let us know to



Via Entry Central we receive certain information about the participant and the person entering the participant, all of which is required for us to organise and run the event including residential address, email address, telephone number, emergency contact details, date of birth, gender, club, Triathlon England membership number and predicted swim time. Entry Central does not share your payment details with us, only the fact that you have paid the entry fee.

To organise our event the race organising committee will have access to all information and will share certain information with other parties including our club volunteers, timing chip provider and Triathlon England.
