Following a MN recommendation years ago, I have Moving Comfort - Juno bras - love 'em. I have 3, they have washed and washed and washed, I think I've had them for about 4 years now so probably time for a replacement. Nothing moves.
Hi Smee - nice to see another not-exactly-spring-chicken runner! I'm 48 too and my knees do complain, but I figure it's better than my heart complaining and giving out on me for getting fat and unhealthy.
I did some research into diets for arthritis as DH gets it in his knees, and I think we've both benefited from avoiding inflammatory foods.
I was also told that doing some lunges mid-run is a really good way of forcing the synovial fluid back around your knee joints to keep everything lubricated. Seems logical but not sure if there's any science behind it!
