NE - it's a 'collect on the day' event. Don't worry too much about checking your number on the website (beyond making sure your name is on the list) - there will be lists posted at registration for you to check against.
For what it's worth - the reason why we have to collect numbers on the day is so that the race organisers know how many people they've sent into the hills so that they can all be counted safely back. I know people get uptight about H&S rules (and sometimes with good cause) but I think this one's an example of how they can be applied to benefit everybody.
So Jane - if you do manage to pass on your number, make sure whoever you pass it to can claim to be you.
I've also just been on the website - there is some important travel information (roadworks between Windermere and Ambleside - Cumbria CC must have realised the tourist season has started!
) and some bad news regarding the kids' races and entertainment. I'd suggest folks have a look before finalising plans for next weekend.
