Big Man Running: Sub 20 5k @ 220 lbs? Is it possible?

For bigger people who like to run, maximizing your potential is all that matters. I'm taking on what may be the toughest physical feat I have ever tried. That's running a sub 20 5k at 215-220 lbs. It commiting to finally breaking that barrier after 11 years of trying.
