Look-UK (the Look Federation) also has places left for a fairly low pledge.
Been debating with myself whether to go for a place this year. Am so tempted as have run the last few years and loved it, highlight of the year. But given that people have sponsored me for various races for the past few years I don't think I could ask for donations so I'd have to cough up most of it myself!!!
I ran the GNR on Sunday and on the start line had the "Local Hero" theme song in my mind which was very motivating (no ipod on!), but as soon as I crossed the line it went out of my mind haha, ended up humming a James Bond theme song instead for the first few miles then talking the general randomness with other runners as you do!
Hope you enjoyed Wolverhampton, I looked at doing it last year but it's tended to clash with the late September/October marathons/training.
