Saw some discussion on the forums about this and was just wondering, since we know we are all running every day, if anyone is getting in more than 7 runs a week. Personally, I am working on building up to a 100 mile week and should hit just over 50 miles this week. As far as doubling goes, lately I have had 1-2 days a week where I will throw in another run at lunch to help me get up to the mileage I want. I know that everyone says you get more benefit out of doing the one longer run, but to be honest, sometimes I just dont feel like running 7-8 miles in the morning. I just want to run 4.5 with my running club and then hit the showers. So instead, when lunch time rolls around, I hit the gym and jump on the treadmill for a half hour. I would never do this for a long run, but mid-week I dont think its going to make that much of an impact on my training to break up a few days. Also, lately I have been testing out some barefoot running on the treadmill - just a mile or so at night, which could be called a double I guess (or a triple if I already dobuled that day).

I haven't done it either, although if you're shooting for a 100 mile week I could see where you would have to. A 100 mile week will be freaking impressive! I have a 2 mile course mapped out in my nieghborhood and I've thought about running that at night every now and then in addition to my daily run. I'm sure I'll work it in eventuallty.
