Hi there is a thread under events for gnr 2014 you may have better luck there. I was injured last year in the week leading up to gnr and managed to pass my place on to someone who could run using the gnr thread .Good luck.
Out running alongside my daughter on her bike which she had just learned to ride but was still a bit wobbly. She wobbled I tried to stop her tripped over the pedal and fell flat on my face on the pavement resulting in losing bottom half of one of my front teeth - it really hurt banging my face of the pavement. Good news was though my daughter stayed upright!
