John! Hey we are on the same team! I am currently training with Team in Training myself. I am preparing to run my very first half marathon after not running in about 15 years and three babies later. Thank you so much for pledgepage! It is so awesome! I wish you the best of luck on your marathon! You can do it! Oprah said recently that if she could run a marathon then anyone can! I know that your friend is very grateful for you running in his memory. I am sure he will be watching from above, cheering you on. Whenever I start to feel weak when I am running I think of my friend and family members who have passed on from Leukemia or Lymphoma and I "hear" them cheering me on saying, "YOU CAN DO IT! KEEP IT UP!" God Bless you for all you have done in the effort to find a cure for cancer!
