Many thanks for such a considered reply. This together with other replies shows just how many approaches there are. I like the speed-endurance advice. I read that Kenyans typically run negative splits in their long training runs and I've been trying to do this on my longer runs (if not quite at the pace of the Kenyans!). I think there's a lot of stuff going on in your head with marathon training and my own particular issue is with my two previous efforts which I did on a shameful training base - something like 10 miles per week, but with a 20 miler (the old 'Worthing 20' which some might recall) thrown in 2 weeks before the events. My training logs read like something that should be published under the title 'How Not to Prepare for a Marathon'
The schedule you've put together there isn't a whole lot different from what I've been starting to do but the big issue is that pesky long run, the prospect of which I find quite intimidating - but that's a bad reason for avoiding it.
Thanks again.
No worries. For the speed endurance runs, I find it psychologically easier for some reason to do them as an 'out and back' run.......feels like a jog out to a point, and then a hard run back.......may be worth a try. Makes the second half feel much shorter. Happy to give a few examples of other sessions I get given if you want them.......reducing ladders (OK), michigans (truly grim) etc. Good for a bit of variety if nothing else.
