Isn't face book amazing. I asked the question on a local running discussion board and one checked with Wallasey AC and another checked with the organisers in Aintree and the word is that they will hopefully be posted tomorrow
I have had a good look around everywhere and I can not finfd them either. They do have a facebook page under Aintree Diabetes but that is showing nothing either. Best guess is if they are posted anywhere someone will put a link in there.
I suppose if you have run an event before or have run a different event by the same organiser then you have a good idea what to expect. You may be more tempted to go for it ( or there again less likely.) So it does make a difference but it is not the main deciding factor. What you get from BTR is good but it does not mean that what you would get from a new organiser would not be.
The problem with a new one would be the level of council involvement. The council has come across as seeing a marathon as something you must suffer rather than something they actually want and there is no saying that a new organiser will come in under strict council terms.
If not a marathon bites the dust which would be a shame.
