Hi, I am very very late to this thread. I was deaf in both ears, following recent op, now deaf in just one (which is an odd one for balance).
BB - did you wear a top with anything on it? I can't hear people/cars/planes/sirens on my left ear, (was in Richmond Park at the weekend and had problems ) which is where people pass. I can hear on my right much more, but it distors where I think the noise is coming from.
I have my first Tri in September , and usually just sit in the pack of us out training, and never considered this as will be on my own.
Freaking out now incase I can't hear and get crunched or crunch someone.
I will have my RNID top on. I am sure I can get something written on that.
God. I was so busy being worried about the scary dolls faces at the bottom of the lake, and the transition time and wearing lycra, I didn't even consider this.
What did you do?
