Hi, I have been doing this charity run for Cystic Fibrosis a number of years, the last two years on minimal shoes. This year I will be doing something different: I will add to the challenge by attempting to run the whole distance without shoes. Just on my own two feet. I have two daughters with CF and am running to make sure more great medications ike Kalydeco are developed and put on the market! This medication changed our lives and I hope such medications will one day soon be available for all CF patients! Support this fight through the following link or through your own national CF Foundation. http://www.run4air.com/en/participants/profile/196 Chantal "L'essentiel est invisible pour les yeux."
