Ben, yeah, Kimi might not have character, but he certainly is a character.
You're going to go through with quite a brutal training schedule. I couldn't even imagine attempting that. Avoiding the heel-strike is a really good idea, have you ever considered bare foot running? This isn't something to try out in the middle of training for a race, but if you get a off season at some point you might want to consider it. About four years ago I kept having foot issues, I had just been running with a pair of cheap New Balances, with a horrible amount of padding in them. Then I bought a pair of Feelmax Osma's, a completely unpadded shoe with a 1,6mm flat sole. Running on rocks was complete torture, because you could even feel a grain of sand on concrete with them, but they forced me to switch from a heel impact to landing with the ball of the foot. I used them for a couple of months while I learned the technique, and after that I've been using Merrel's barefoot line. They have about 4mm thick soles, so they protect the foot a bit, but still allow it to move pretty naturally. Immediately when I dumped the padded shoes I noticed that I was running a bit faster, and I could go longer distances. My stride was also shortened, and the pace of my steps sped up a bit. The first two weeks were complete agony, for two days after each run my calves were blocks of concrete. I could barely walk. But that was just the muscles getting used to a new technique. Now I couldn't even think about going back to those shoes that are designed to "protect your foot and lessen the force of the impact". Some people like those Vibram Fivefingers things, but they are really not designed for my feet, and while I consider myself to be quite open minded, there's a limit to how ridiculous I'm willing to look.
Of course the most comfortable way to run is to ditch the shoes completely, but it usually gets pretty nasty unless you're running on grass. It takes quite a while for the skin of the soles of your feet to develop a hard enough surface to run on harder surfaces like gravel or pavement.
