I am absolutely in love with the expo at this race and I will definitely come back again and again for all the SWAG! I ran the 2nd Half in 2013 which was a great race! I trained for hills, so it was not nearly as challenging as I thought it would be. There are LOTS and LOTS of people, so if you like big races... this is a great one for you. The weather in SF in July is overcast, so it is perfect for racing. I love this race so much, I am coming back in 2015 to do the 1st Half (over the Golden Gate Bridge). I know... I am excited too. Stay tuned for my race review!
