As far as the leg sleeves go, I have decided to wear them. My legs are at that point where they could use a little extra help, and if I can reduce the amount of pain and discomfort I experience then awesome.
On a really positive note, all this training has helped me lose quite a bit of weight. I'm not sure how much I lost because I haven't been weighing myself, but I'm wearing clothes I couldn't wear last Spring because I gained too much weight the prior Winter. Talk about an awesome side effect from all this training!
