Couch Potato Puts on Running Shoes

So, I signed up for the half marathon in October. Ummm. I'm not a runner. I figured I would walk it and see how far I can get without passing out. Remember blue lips, sweat drips? Yeah, I faint at random areas. But, I'll update you on the fun "training" I'm doing. Hopefully, I get to keep my knee caps and I'm not a bff to shin splints. Eeks.
