This is my very first half marathon. The first 5 miles was relatively flat and was easier. Then came the Golden Gate Bridge for 4 miles which has a little uphill both ways. After that came the SF street roads which were a nightmare to run on. Was walking most of the time I went uphill. Tried to run as much as I can on the downhills and flat so that I can finish it in 3 hours and I did it. Yay!! But honestly, the crowd makes it a little easier.
For practice, I ran 3 – 6 miles quite a lot, 10 miles once before the half marathon. Apart from that, the general workout at Ironwill CrossFit helped me with this run.
