I'm thinking a trusty pack mule is the only way to go--that would be my younger brother. When I went to visit him in Europe, we were late for a train and I was slowing down the process... so he grabbed my backpack, probably a good 50 lbs., was carrying his OWN pack as well, took off running, and I STILL couldn't keep up with him. Not bad for a skinny white boy.
Unfortunately, I couldn't convince him to lug around my stuff for the rest of the trip. And I probably couldn't get him to do it now, either.
*Sigh.* Second job, anyone?
