Good I needed that knee video! - I getting sore knees in school and after runs. I was told the problem is that my quads aren't strong enough. Thanks for the video I'll finish watching them when I have more time. Say, Brian - Are you running in the GR marathon? I see there is about a month left before the race and was considering doing it. Looks like you and I run about the same amount. Maybe we could challenge each other till race day to try and get back in shape.
