Katherine Switzer, the first woman to run the Boston Marathon about to run the London Marathon at 71. I am inspired p.  The 10 k Sun Run today and reminds me that I did it many years ago and that I owe a debt to Katherine Switzer. I needed to get off the sofa and do my 10,000 steps in her honor today.
