No headphones allowed and there's a time limit of 2.5 hours! Neither one should be a problem really but there was no mention of either when I signed up and now I'm stressing about it.
I'm expecting to do it in about 2.15 - 2.20 so may be cutting it a bit fine if something goes wrong. I'm worried that I'll stress out and go too fast at the beginning and then run out of steam, or that it'll be really bloody windy, or that I'll have to stop for a pee.
Someone please hand me a grip!
