Could you please check that the time entered for the Wycombe meet is correct and let me know if not. If you are happy for them to swim for the time you registered them at, it will have to be as a time trial. So that means you will get an official time but you won't be eligible for a medal.
Please email me on email@example.com.
If I don't hear back, I will presume that you are happy with your time and that you would like to do a time trial.
