Why the hell would you wanna run 9 or 14 miles ?
I run 4 miles (well, before my quad accident) and for me that's really the limit without sacrificing mass or at least gains....
I tried running more, an hour a day. Got lotsa stamina and a nice slow heart-beat, but my squats weight went down, even though I ate enough calories and proteins.
You just can't have your cake and eat it.
Wanna look like a marathon runner? Keep running.....
