Is the course a certified course, as in, has it been measured using guidelines similar to those of USATF? If so, that is part of the reason the course is a little longer than 13.1. They usually go a little over because if someone was to verify the course and come up less than 13.1, they would have a lot of issues. As you said weaving would add a little distance also. How well did you run the tangents? Courses are measured using the shortest path possible, so if you run in the middle of the road for the entire length of the race, you would also be adding distance. The last thing to contribute to extra distance is simply, GPS systems are not 100% accurate. So over the course of 13.1 miles you ended up a little over .1 over which given all the variables isn't all that bad. Easy on the race officials, most of them are volunteers and are their for a good cause. Again congrats on the race and PR!
