Running the Peachtree Road Race early this morning is one of many ways Kim Martin celebrates the fact she defeated breast cancer. Martin, 45, will be right there alongside almost 60,000 other runners at the starting line in Buckhead — rain or shine — for the fourth straight year since she was first diagnosed on August 26, 2009 after a routine mammogram. The Cumming resident will be wearing her patriotic colors, like so many others, but look closely at her ankle and you could see a permanent reminder of her story: A pink tattoo of a ribbon with the word ‘survivor’ written underneath.
