No, it’s not a speed drinking contest. The chocolate here refers to theĀ mugs filled with hot chocolate, chocolate fondue and other goodies that every runner gets when she finishes. These 15K (9.3 mile) or 5K (3.1 mile) races are run on various dates at various locations nationwide. And yes, there is an expo afterwards too which you naturally won’t want to miss since there will be plenty of the good stuff (chocolate) to go around.
