JPG, thanks for your kind words. I'm very happy to be here. As I noted, with all the holiday activities, I've been a bit lazy about posting. I guess I wasn't even lurking well, because I didn't notice that many people were receiving the same flood of Emails that I am. As you have noticed, I do also spend a lot of time over at Letsrun.
In 1999, I joined a gym that opened near my office. While I had worked out at home for many years, it was my first time at a gym. Subsequently, a couple of newer fitness centers have opened in my immediate area. With each new opening, the masses have flocked to the latest, greatest facitility. I, on the other hand, enjoy the comfort and convenience of staying at the same place. Eventually they may close, as the competition becomes too strong, but until then I plan to stay there. Given that history, I don't see myself leaving my buddies at CoolRunning anytime soon.
I read your question to Jim about running on grass with great interest, as I too am always looking for off-road surfaces. About 75% of my running is on relatively smooth dirt trails (i.e. not too many rocks and roots, although I always seem to find something on which to stumble). I've noticed the last few days that I feel somewhat beat up, with various aches, and then I realized that most of my runs for the last couple of weeks have been on pavement, due to the snow and ice. I've managed a couple of recent forays on the trails, and I'm hoping the weather will improve enough for me to get back to them with regularity.
Fred, I totally agree that most of our loss of speed with age is related to decreased stride length. I have slowed disproportionately to my age, due I believe, to chronic soreness and shortening of my hamstrings. I do a lot of functional training similar to what you describe, but perhaps I need to become more rigorous in following a program. The problem is finding time, as I already log a load of mileage, and I make an effort to maintain a strengthening regimen in order to have at least some balance of musculature in my upper body. The biggest problem I see with the video you posted is that the woman on it is way too hot, so I coudn't focus on what she was saying. I'm going to need to go back and have another look.
Happy New Year everyone! See you on the January thread.
