Hey I had a question.. do you see the same benefits doing "doubles" every day that you would doing "singles" of the same mileage? Do you choose to do doubles because it better fits your schedule?

I am really just starting doing double a significant number of days per week. There are a few things that I know for sure. Every elite runner runs 2 times a day most days except some kenyans even run 3 times a day lol. All successful college teams use doubles most days (except oregon back in the day... but look at adam goucher now). It is definitely easier mentally and physically to do high mileage with doubles than with singles. And there was a study done with one group doing 20k easy every day and another group doing 2 10k easy runs every day and more improvement was seen in the 2 10k group. Basically I decided to start doubling because I wanted to up my mileage just a bit and running more than 8 on a daily easy run just wears me down eventually. We will see if the same thing happens here.
