Really, I kind of started doing the 10 milers last VRAA because I hated scoring less than 40 points per day. I had been averaging 50-55 miles per week probably last Fall, so I thought I wouldn't be able to maintain that, but since I was going so slowly, I ended up being ok. I've run by time before, and I find it to be pretty pleasant, but since I had committed to running a lot slower to try to build my base, I didn't want to go strictly by time and end up doing a lot less mileage.<br>
I know I need to vary my daily distances more, and I'm starting to do that. Anymore though, I just don't feel like I've gotten my day in untill I've done 10. I'm planning on giving the Pfitzinger 70+ plan a crack this Summer/Fall, so that opinion will probably change, and I'll cherish the rare <10 day.
