7 weeks til the Grand Canyon hike

I did a 12 mile hike again today. There was considerably more up & down than last Sunday's 12-miler. Today's hike was all on Cowle's Mountain and it took 3 hours and 57 minutes, not counting a few brief breaks. My hip behaved pretty well once it got warmed up. My lower back has almost returned to normal but I'm having some sort of piriformis/glute issue on the same side as the bad hip. I have to admit, though, I had absolutely no problems with dozens of other body parts. The weather was cool and it even rained a little. I only drank about 30 ounces of water and had a granola bar - I've got 7 weeks to get back to October's Grand Canyon hiking weight of 170 - I'm at 177 now. Lotta 7's there.
