Wow so many great tips, advice, encouragement and case histories I don't know where to start or who to reply too. I have read each post and haven't found one that doesn't have logic and good common sense at the heart of it.So:

>I'm going to start watching calories closer. I admit that the 80-90 miles I've been doing a week has given me a false sense of thinking I can eat more.

>I'm going to start doing intervals ,well fartleks to my weekly routine.

> Add another 20-40 miles a week.

> Post again with any progress as communicating with all you great folks helps immensely.
