At one point in the run I caught up with another runner who was obviously focussed on running, and when i said 'So, you didn't get the memo then?' as a way of breaking the ice he just went '... huh ...' - so I decided to overtake him and run on to the next bit. (That'll teach him).
Today is probably the last run in the original gorilla head - I have a new (smaller and lighter one) which i'll be trying out for the Reading Half - as it was a bit fruity in there today.
Finally, I must say the response from my work colleagues today was fantastic - lots of encouragement and sponsorship.
Thanks so much everyone.
