M...eldy, havent got a tape measure to hand

I think you are all right, very borderline and I guess a decision I don't need to make for a while. Doing one slightly further out would definately be the best option, and I could just come and support at Eastnor 
Haha yes Mellifera for full IM
last cross country half I did it 2hrs 14 and did brighton marathon in 5hrs 5 mins, obviously I'm hoping a I can vastly improve this over the next 12 months, I get into the habit of doing a pace then I can plod on forever for 
I definately train regularly (5-6 times a week) but I think my problem is more that there is no structure, probably because of my inexperience and also as I had no goal to aim for.
Can I just say thanks so much for all of your advice, it is so lovely and greatly appreciated
