Okay, so I visited super chiropractor Dr. Matt (the guy who saved me from shoulder surgery and has me swimming again) about the crackling sound in my knees when I do deep lunges. Actually, kind of shallow lunges, too. He called the noise knee mice and explained that my cartilage is in bad shape. He prescribed glucosamine, and if it doesn't improve, he'll start deep ultrasound and TENS on it in a couple of weeks.

Now, my question here today, because today you can register for the San Diego Rock & Roll Marathon at a discount, today only, is whether or not training for a marathon is just asking for knee-deep disaster down the road.

Literally. I've never been much of a runner, so this is all new to me. I can run, and according to my runner friend, I have a good natural form. I just don't do it. All that pounding just hasn't sounded like fun. But a bunch of my friends are signing up for this marathon and we'd all be training together.

But a Girl Power Goddess Experience isn't worth a lifetime of arthritis or something if all that running is just bad for my knees.

This is the next step on my road to triathlon training, too. If I can't run, I can't do triathlons, so I really want to. I'm just facing down the potential injuries here.

Help, please.
