I ran this race and the markings they had were very hard to see and know where to go. I got lost seeing other colored arrows and having to run at least another mile going off course. There was nobody in the course to help out directing runners where to run.
I agree with Kathy116. There was a marking for a 10K and also a 5K. I followed the 5K arrow and ended up in a random neighborhood alone, joined back in the race later, and then had to tell the officials that I didn't fully run the course. There needed to be better markings and directions. A course map in the registration packets would have been ideal!
