Love this race, ran it twice. PR'ed my first time, bonked the second, mostly due to mediocre training, an aggro crowd in the early stages that I ran too fast early on to try to avoid, plus a deep doldrums over the course pathway from mile 12-17. They re-route this course often, though, so I wouldn't necessarily worry about that too much. Overall, a totally quality marathon experience and you can never go wrong racing in San Diego.
