Overall great course. I had mildly sprained my ankle the weekend prior at a trail race, but I'm a bit stubborn and decided to run the half distance anyway. The course is so easy and I didn't have to worry about possibly re-injuring myself. The weather this year was perfect! The only elevation is the underpasses and they are easy to overcome (or walk thru) without it damaging your time to much. The post party is always fun to be a part of. My only hiccup was the ridiculously long lines for Karbach beer station, in which they ended up running out. Otherwise, overall great race to run and be a part of!
