David, our oldest son, is running in the Boston Marathon today with an enthusiastic audience of cheerers. Since he was recovering from an injury only a month ago, we hope he is able to finish in the time he wants. From my point of view, finishing at all is amazing. Even in my younger days running a marathon was never on my bucket list. But I managed to raise a bunch of runners who like to do marathons, half marathons, 5Ks, etc. Walking five miles is my idea of a marathon. Good luck, David! Hope the weather is perfect for a great run.
