My Forum

I am not concerned whether the rest of my training appears bad. I've ramped it down for various unchangable non running reasons over the last few weeks, but kept the double as it works well logistically doing it. I'm not looking at any changes before November at the moment with a marathon 3 weeks off.

My question really was that I've read a lot about pros doing double runs in a day and I'm interested in the difference between say 10 miles twice a day and 20 miles in the morning. There must be a reason for that split. I'm running the 2 runs significantly harder then I would if i did it the same distance in one go and I wondered what the effect of the faster pace with a small recovery windows is? Doubling seems to be a technique that is mentioned a lot, but never with much science behind it. Is it just time saving or a good way to get a faster longer distance in in one day? At the very least I must be burning more calories through more effort and with a bit of luck i'm pushing my lactic acid limits. Anyone seen or read any good science on it?

M Mariane - good luck with the half in Munich

Once a week I'm running 11 miles to work, working, and then running the 11 miles back in the evening. It obviously doesn't feel as hard as if I did the 22 miles in one go and I don't know what to log it as on my training, mainly because the break makes it hard to compare to other long runs. I wondering what people think, should i think of it as my weekly long run at 22 miles, or two runs at 11?
