I agree about the atmosphere thing. The only other race I have done was the 5k hydroactive in Birmingham, with over 5000 runners and lots watching, so that was great. I chose Stafford half, not just because it was quite local and flat, but also because it had the larger number of participants than the others, this has two advantages one to add to the atmosphere on the day to help me round, and two to minimise the chances of me embarrasing myself - the more people the better. I am not doing anything where there is only 100 runners and the slowest time last year is twice as fast as what I can do! I want to be motivated.
That is what I think about the FLM, with a huge cheering crowd and 40000 other runners I hope pure adrenaline will get me round, and if not nobody will notice me lying in the gutter at tea-time!.....only joking.
Seriously, I admire all of you for entering these tougher races.
