To be honest I'm all for the proper safety rules but the current draft of the rules is also looking a bit like 'lets add all sorts of other bureaucratic stuff thats not nearly so important while we're at it'. The not allowing folding of numbers and insisting that they are pinned to your vest is just petty dabbling. Insisting on runners wearing a top is overkill to, although given our weather most runners do most of the time anyway. Yes it could a little bit easier to see a number pinned to your chest..... unless you've lost a safety pin, put on your waterproof or fallen face first in a bog..... but, really, whats the problem with pinning it to your shorts? Yep, you're right there is not a single problem
