.....because I've just signed up to do the Great Yorkshire Run in September 2013. 10K around Sheffield.
I've never signed up for a race before (only started running in January) but I went to the 2012 run as a spectator and there was a great atmosphere. One of my friends has done every one of the six they've held. I signed up within the first hour of it opening for registration. Blimey, that's keen!!
