    The course was officially measured by the USATF to be 13.1 miles. It is a common question as to why a GPS will typically measure a certified course longer than the official measurement. There are a few reasons for this, but the most common is that a GPS is not 100% accurate and the little errors accumulate over time. Imagine measuring the distance across a park walking a straight line compared to the distance you would measure if you were to meander across the park. The meander is going to be longer. The same is true for a GPS. Because of small errors (and sometimes not so small errors), a GPS will have you meandering as you go. The other source of error also comes from the fact that the certified measurement is on the shortest possible course, which means they measured against the road tangents. If you primarily ran on one side of the road rather than cutting back and forth to run the shortest possible course, then you will measure a longer course. Hope this helps.
