Due to the recent cold weather have been taking my evening hikes indoors to a local domed facility with a astroturf walking/running track.
That stuff is murder on your legs, knees, and ankles. I've only been there two times now, but my hip joints and knees are killing me. Going to give it another week and if I do not start getting used to it I will have to hike in the frigid cold or go to the gym and stand on a treadmill and I hate walking on a treadmill staring at the wall or a TV.
At least at the walk around track you have some ladies to look at as they jog by and you can watch the kids in the center fields play footbal, soccer, and Lacrosse.
