Last year we entered the Tandem Tarts Time Trial, organised by Sotonia CC. We didn't die, nor fall off (we were on a long barrow). We're having another go this year.
Are there any rules regarding electronic devices? I want to use my phone to "navigate" the route so I know how far we have to go, that sort of thing. I don't have a dedicated cycle computer. Can I have it squawk distances into my ear?
I've had a look at the Rules and Regulations on the CTT website but couldn't see anything.
