As this will be our first Hobble, and the first long distance race I am doing in the UK, I have some questions regarding the equipment. Could you please tell me if, in a team of 2, both of us need a copy of the OS Map? Also, I was planning to take with me a Goretex cycling jacket that I also currently take with me as an emergency jacket for long runs. However, I normally don't carry waterproof trousers and the pair I have are quite heavy (more suitable for hiking). Obviously, if the weather is at risk of being as bad as it is at the moment, I would carry them, but does the mandatory "full waterproof body cover" require waterproof trousers, or would a waterproof jacket (and possibly a safety blanket) be sufficient?

Thank you very much!
