Let me go on, like a blister in the sun

I happily existed in the land of non-injured runners for about a month before my marathon in April, and miraculously made it through the marathon with no injuries to speak of. Somewhere in the weeks after, though, between gradually building back up to weekend long runs and my lame attempts to do speed work and hills, I've re-entered the running injury twilight zone. If it's not one thing, it's another. For one thing, my right hip has been bothering me on and off for the last few weeks. Not seriously enough for me to break down and call the PT, but just enough to be annoying on my longer runs. My right foot decided it needed to get in the game as well, and has been aching on and off. I mostly attribute this to some poor advice from an orthopedic "specialist" who looked at my foot for no more than 5 seconds and told me that I needed to switch shoes (when I had run in my Asics 2140s for years with no problems).

Well, my problem last night on my three-miler was not my right hip nor my right foot, nor even the 90+ degree temperatures and soup-like consistency of the atmosphere. It was the giant, quarter-sized, angry, red, possibly infected blister that appeared on the inside of my right heel somewhere toward the end of last week. It started off innocently enough, a tiny blister caused by my shoe rubbing a bit on that heel. I've had these before, so I wasn't very concerned about it. But last weekend's 10k race followed up by a 10 miler the next day turned that thing into a complete monster, the blister to end all blisters.

And yet, because I'm not smart enough to know what's good for myself, I took myself and the monster blister out for a three-mile run last night in the aforementioned disgustingly hot, nasty weather. Not without precaution, though, I did cover up the monster with a Band-Aid blister ampule, which I think is one of the best things ever invented for blisters:

I also duct-taped over the offending portion of my shoe and body-glided my foot, my sock, AND my shoe. This worked for about the first mile and a half. After that, I realized the band-aid was starting to slip and I was sweating so much the body glide wasn't about to do me any good. Long story short, despite my best attempts to keep it from happening my three miler tore that blister wide open. Which felt really awesome when I got in the shower. I was about to take a picture of the sucker and post it on here, but I think it might violate Blogger's prohibition of obscene materials.

Which leads me to my question for the day - I love the Band-Aid blister ampules (and have also used some sport-specific bandages that are very similar) but I have never been able to get them or any other type of bandage to stay on during a run long enough to do me any good. I once tried to duct tape over the band-aid on the suggestion of someone at the running store, but the duct tape just tore up my skin. Does anyone out there have any suggestion on how to treat running blisters and how to protect them during a run?
