The Cape Cod Marathon was sponsored, ironically enough, by Dunkin Donuts. Yes, I know that America supposedly “runs” on Dunkin, but the free pre-race doughnuts seemed a little much. As I ran the seemingly infinite 26th mile, I concentrated on my congratulatory doughnut. Throughout those last 1.2 miles, I fantasized about a doughnut with chocolate frosting and those autumnal orange sprinkles. As I passed the finish line, my eyes searched for the table of doughnuts, but all I saw was water and Cytomax. That night, I treated myself to something far more fattening and far more delicious—Toscanini’s B3.
