I'm interested in hearing from 2:45 guys, because I am in similar shape right now. 3:10 or whatever Reg Fields ran last year, not so much. If I needed advice from a 3:10 marathoner, I could just ask my wife.
And, Wang, if your wife can run 2:45, I'd love to hear from her as well. Just not Reg Fields.
If I wanted to "break 3 hours" I could just ask your wife as well.
