The repeated attention that "Badger Miles" gets makes me laugh--this is not the first thread. It's just not that big a deal. And actually, the fact that the concept seems to aggetate so many people is exactly why the concept exists: too many runners obsess over mileage figures and so some coaches insist their athletes count their mileage conservatively and without regard to pace. And that's all "Badger Miles" are, an attempt to deemphasize mileage figures and recovery pace. It's a way to discourage people from becoming mileage freaks.
A mileage freak just can't bear to write down "45 minutes, 6 miles," when they actually ran 45:32 and probably covered 7.2 miles. They want that extra mile for their log. And more likely, they'll circle the parking lot twice like a dufus so they can call it 46:30 and 7.5. They're the ones whose logs are kept to the quarter mile.
The number becomes the focus, rather than running the appropriate volume at the appropriate pace to be ready for the important work--the structured workouts and races.
(Others want to write in their logs nothing but 6:00 pace or better so they end up pushing runs even when their body is telling them to take an easy day.)
All "Badger Miles" do is try to discourage these compulsions.
