The course is poorly marked. I signed up for the half marathon and there was one sign when it splits to do the full vs the half. Well, I got on the full route and didn't realize it until a family member called asking where I was around mile 8. I asked the cop to confrm the route I was on and he said there are a lot of runners who take the wrong route. So I didn't finish my goal of doing a half marathon and wasted $85. Also, the communication of where to go, packet pick up was not very good. I also did not like that the start and finish line were miles apart.
Do a different race, especially if it's your first and your nervous and excited. Or you will end up disappointed in yourself and feeling horrible.
