There's been a lot of discussion on the general boards about both the 10% rule and rest days, so I thought I'd combine the two in a super-duper question: I'm chasing the bunny way back at the pack, with the goal to slowly gain on him by the end of the year. Right now, I'm on week 7 of the couch to 5k program. So, 3x a week, a little over 6 mi/wk right now. On a couple of the four non-running days, would it be useful or harmful for me to take a slow mile or so, just to keep my legs active and add some mileage? Or should I wait until I'm up to 9-10 mi/wk to add a day, even just one mile?

I thought that's what you'd say. Got it.
