Well, they ran the race yesterday, using their own start line (the finish was moved a bit too, further shortening the course). To make matters even worse, they put down mile points in the wrong spots (although probably accurate given their moved start line)
To be fair, none of their printed or online literature states that the course is certified. Also, my own marks, smaller but in the same color, were still visible from where I painted them last week. That must have really confused the runners!
When I did the results, I based the pace calculation on the slightly shorter distance. I felt at least runners would get that piece of info accurately.
