At about 15 or 16, the 150 miles in one week was 35 miles one day, then 2 days later running (not walking) 20+ miles a day with my 
buddy, with lightweight backpacks, sleeping in parks or just on pavement in driveways along the highway.  We had another 60 to go to 
our goal, but his mother picked us up after he mentioned knee pain on his daily calls.  We could have done more than 20 miles per 
day easily, but wanted to pace ourselves and it just happened that the towns were roughly 20 miles apart on our route, with nothing 
but farmland between.

I had some unexplained severe hip socket pain a few years ago.  After sitting at work, my hip would get very sore and I had 
difficulty straightening for a bit.  As I happened to be working with someone who had had hip replacement early, I became a little 
wary.  Since then, nothing, so it was probably nothing, maybe a temporary bruise.

I posted some articles about this on FoRK last year:

Humans are apparently the best long-distance running animals by far.

Interesting!  I wonder what the dock, plunder, claim, establish, move on cycle was.
