I wish I could run. My knees have been shot for years. I've had surgery to replace ACL's but I just can't deal with the pounding on my knees. I love to hike and walk fast. I usually do about 3-5 miles every other day somtimes less when I get home late from work. I'm back down to my same weight before vaca and a week away working outta town. Now to get back to my goal weight.
