America's Marathon has been designed for serious runners looking to run personal bests, Boston, and Olympic Trials qualifiers.  Runners in both the half and full will enjoy the pancake flat, lightning fast, wide open country roads of western  Douglas County.  They will also enjoy the small town charm of our host cities, Valley and Waterloo.  The course is literally a race track with long stretches of wide open roads allowing runners to hit their strides and keep their momentum.  The full marathon is two 13.1 mile loops, making our half one of the fastest in the country as well.  You will run past many of our deepwater lake housing developments, showcasing the natural resources and beauty of our communities.  All while being offered the chance to "Run To Your Potential".  In compliance with City and County directors, we are adhering to a 5-hour time limit, further ensuring a fast course and fast field.
