I've done 1 mile in 6 minutes. I actually went a little bit beyond the mile before i died and went to heaven. I could probably do the 3/18 if I put my heart, soul, energy etc. into it. That, and I would have to quit drinking beer (don't see that happening anytime soon).
So i guess i basically really have nothing to add here except that I'll give it a shot. Stay tuned.
