Anyone interested in the above, the organisers have sent me the following:-
'We're delighted to let you know that the nation's favourite 10k running event is now open for entries and will take place on Sunday 26 May 2013. We hope you will be part of a fantastic sporting weekend in Manchester.
Up until the 30 November, or when the 40,000 entry limit is reached, whichever comes first, the entry fee for the Bupa Great Manchester Run will be £37; the same price as for the 2012 event.'
I didn't realise they were so expensive.
