The reason I ran this race was for the Half It All Challenge! The challenge is to run both halves of the full San Francisco marathon course in consecutive years. I ran the first half marathon course in 2015 and finished the second half in 2016. Review for the 1st half marathon: http://www.bibrave.com/races/the-san-francisco-marathon/3662#.V9DsBCMrIy4

Race Course-
Overall, the course was flatter and faster than the first half. However, the views of the city were almost non-existent and it felt like we were running thru Golden Gate Park forever. The park was rolling hills and I kept wondering to myself when we would exit the park. After the park, it was mainly city streets. There were long stretches of time that felt boring and very few spectators. The main exciting course view was when it ended near AT&T park (SF Giants stadium).

Aid Stations-
I felt they were better spaced and stocked for the second half.

Tshirt/Medal -
I liked the color (grey) of the shirt better this year. I also liked the medal this year more too. The half it all challenge medal is even better!

Final thoughts-
I would recommend the first half for the views, especially if you want to run across the Golden Gate bridge. If you're looking for a faster course, then the second half is your answer. If I put the two courses together for the marathon course, I think you'd have to dig deep mentally to get through the long stretches during the end part of the marathon.
