We've updated our Terms and Conditions so that it's now possible to swap between contests on the event you're booked onto up until the close of Registration on the day.

At one event last year, we had over 300 surplus t-shirts and we want to avoid so much waste at future events. The updated Ts and Cs advise that if you do not confirm your details and / or start time when requested to do so by email before the event, we won't order you a t-shirt but instead put its cost towards our BiodiversiTee initiative.
