I think from a scientific perspective nobody has a much of a clue on how the body deals with it, or most food related topics to be honest. It's why nutritionists are nothing but a joke.
There's contradictory evidence from either side of the argument. Personally I'd just experiment and see what works best for you. I'd think there would be a difference in fuelling from elite athlete downwards anyway. Even just on a basic principal of energy spent x time running. Add to the equation you're average runner wouldn't have the time to train to an elite schedule, or have access to their recovery plans and equipment. There are too many variations in just that to deal with to have a 'you should do x, not y' approach.
KS - Sorry can't help with that one. I've never tried a run/walk strategy. I have to admit I'm time motivated. The races I've ran poorly in for what ever reason always feel like a let down, such as Loch Ness last year. I never feel any sense of accomplishment unless I've gone for it.
I think you just need to decide what you want from the race and how your form is and take it from there. If you think that run/walk will be better for you and you'll enjoy it more then there's no harm in trying that.
Jokeybhoy - I know what you mean about not being able to race a half. I couldn't turn up at a half and not go for it. I have a 10 mile race next weekend, three out from Stockholm, so I'm doing my 20 mile LSR on Thursday night.
A windy 18 miles for me this morning. Might treat myself to the new Avengers film tomorrow. Hope everyone is having a good weekend.
orapidrun - I think it may be slightly more than 8p a pint these days. Although if that's your holiday criteria I thoroughly recommend Vietnam!
I'll decide what I'm doing after Stockholm. I could easily do a cheap trip in Europe if I do Amsterdam. I'd just be travelling by myself, so I can slum it in hostels or cheap airbnb places with my backpack.
Meadower - I'm not sure yet. If I'm in The Netherlands I'd no doubt pop up to see my friend who lives in Zwolle. I also want to get back to Berlin and spend some time as a tourist there as I loved it when I went over for the marathon, but didn't give myself enough time to really explore the city.
