In reply to Tony the Blade:
Crikey - I totally forgot I'd asked this question, sorry.
Having now thought about it some more I have to report that I'm not entering the 10k this year. I decided that I'd rather spend £250 taking our lass somewhere nice over half term and maybe entering a local half/10k while there.
I am however entering the marathon next year, this has always been the case and is what I'm currently building up to.
Thanks for the replies guys, belatedly appreciated.
