ahem...Mr Twatt...are you for real?
As in your last post you said the below...doesn't look to be the "casual" training you state 
"My approach to running has mellowed quite a lot over the years though. I used to read all the physiology and training books and spend a lot of time thinking (possibly obsessing) about my training. Now, I just have a vague plan of what I am going to do for the next couple of days, and sometimes this can change. I think this is partly because I feel I have got to the stage where training principles have become more instinctive, but I think it is mostly because I can't really be arsed spending much brain space about whether my tempo runs should be 10 seconds quicker per mile or my rests on mile reps should be 3 minutes or 4 minutes, or whether my easy pace was slow enough. I still enjoy running and racing as much as I used to and I can train very hard when required, so it's not a case of losing motivation, but I prefer to be more casual in my approach.
I think that a good proportion of people on here may also take a slightly more laissez faire atitude to running. It is an outlet from our normal duties in life, and who's to say that a person who likes running marathons can't do it on say 30 miles per week if that's all they want to commit on a weekly basis."
