My wife and I hike at about the same speed with one exception... we've known for a while that her knees and behind the knees bother her. After a ten mile, steep hike this weekend her knees hurt her so bad she walked un-naturally the next day. I'm pretty sure the behind the knees syndrome is sore muscles, but the actual knee pain is something more. We recently bought hiking poles and this has helped a good deal... she also plans to lose some weight even though she is in good shape.
Just wondering if anyone knows any other things we can do before our attempt at a 2008 thru hike to help strengthen her knees...has anyone had success with glucosmine (sp) or the new supplement advertised in backpacker a few months back?
