It's so ironic, isn't it, that 800m and 1500m athletes will have months of 80-120 mile weeks in the bank, yet well meaning individuals and media will tell new runners to get into a marathon on a base of winter season sprint training.
Two weeks off, DT19? I'd go away to the sun, but sleep comes a close second.
That was an interesting experiment, Dr.D. It emphasises the impact on the bodily systems of forcing them to work to make energy available, which ultimately makes those systems more efficient, and contrasts that with the ease of supplying the energy ready made, which reduces the workload imposed on the body whilst performing. Train Low, Race High has been mentioned many times before, certainly in MG since prf ran that sub-3 mara on stretching his unfuelled long runs. What seems to be extra here though is that switching to LCHF improves your efficiency almost without the mileage - I'd be interested in a control experiment to see how various training amounts impact efficiency when on the same LCHF diet.
Sugar. There's a message always seems to appear from amongst low carb advocates that prehistoric man ran everywhere fuelled by mammoth steaks. Amongst the many things we haven't got a clue about pre-historic man, one assumption that's remained fairly constant is that we were hunter-gatherers and one fairly well supported theory is that our diets were eclectic, pretty much anything we could find as long as it had the energy output to keep us alive and reproducing. We would have eaten high carb veg when possible, simple carb fruit in season, and no doubt honey when we could find it before the bears. Sure, we didn't refine sugar and bake with it, but humans didn't avoid carbs when they were in stock. Now that we have the luxury of selecting our diet, I think the idea of looking at various foods as 'tools' for what we want to achieve is actually a very healthy one!
Plain old water will get you through a half marathon. To perform a bit better in it, 'available' carbs, ie. those you've eaten recently, will help. A decent breakfast should do it.
But plain old water won't get you through a marathon at this stage of your running career. It's good to train without relying on snacks and sweet drinks to get you through the miles, as it will improve your capacity to go further, but on the day you will need some sweet support. Gels are an option, but if you want to use them it's better to try them out first in training just to make sure you can stomach them. People have different reactions, and to different gels, even to different drinks, so make sure anything you plan on using you've tried out a few times first.
Oo, yes, happy 900 alehouse! Glad to get you on the bandwagon for the 100's! I thought about the sit-ups but decided that push-ups are just planks with benefits. As it's getting on for ten minutes already (tomorrow's set is 90s rests) I figured I didn't want to add so much exercise that I couldn't fit it in and would therefore give up too soon. It's hard enough already with the house puppy always interested in what I'm up to!
Science the sh1t out of this, Dr.D, you know I would. Parkrun, 20ish mins, about 250 kcal? Eat a snickers with breakfast. Ready carbs and all gone by the end of the race. Plus, snickers contains nuts, so one of your five a day.
I spent most of today daydreaming about starting running again. To blame was the fact I started reading this thread back from the bottom of 868.
