I've ran the RnR San Antonio is both 2016 and 2017.

While San Antonio is typically in the 50s this time of year, I had the terrible luck of picking the TWO years that it rained. 2016 was my first marathon, and I will admit that it was a rough race. This race is front loaded, with all the tourist spots and the beautiful parts of San Antonio in the first 13.1 portion of the marathon. After that, its an out and back south of town with not much to see. With the rain, much of the entertainment couldn't play. So it was just you and the pavement. The second gel station was completely out by the time I arrived, but luckily I didn't rely on it and had my own with me. I wasn't even the most back of the pack, as I finished at about 5 hours. They had two more hours of being open and they were closing up shop!

The second time I ran this race was much better (2017). It was still a rainy day, but rained maybe for two miles rather than the whole day. The aid stations were better stocked, and the entertainment stages went past the 13.1 (even if the scenery was still lacking in the second half).

Having ran this marathon twice, I would say stick with the half marathon for this location. The first 13.1 really are awesome! I especially love the "Mariachi Mile" but do a full marathon somewhere else.
