Marathons range in size from a few dozen runners to tens of thousands of runners beating a path to the finish line.  For many, running in these "Top Tier" marathons is a 'bucket list' goal.  It can be frustrating to get stuck in a pack where you can't break free of the crowd, but for these races, it's all about the experience.
