For those in the know, my little dream of returning to the Boston Marathon came to a stumbling halt at mile 18 of today's marathon, courtesy of a fragile knee that got a bit fragile-er. Before we fire up the pity wagon, however, I should also mention a young woman I shuffled up alongside at mile 24, in tears after deciding to quit. With TWO MILES to go. We had a brief conversation, she dried her tears, put back on her number and we stumbled to the finish together. Boston can wait. Time to get healthy.
