This has been a really intresting thread to read. Gosh, I didn't know that the majority of you all liked the trails that much. Wow. I guess I was from a different planet or something.

Many years back I trained on concrete/sidewalks. This totally killed my joints, so I said forget it. So I have now moved to trails. Around here there are places where it is very sandy, as if you were at the beach. The only difference is the sand is red. I think that is what made my first run so hard. I was using al sorts of muscles that had not been used before. My feet were placing differently too. There is hardpack/gravel/unpaved roads. I have taken a run on one of those yet.
