I had an overnight in San Francisco while on a cruise. I found this tour by searching here on tripadvisor; I called for a last minute tour and John scheduled one for early the next morning. It was a great experience. John customizes the tour to the runner's needs: he ran at my pace (slow), at the distance I was interested in, on a "course" I requested (I was looking for fairly flat--not necessarily a small feat in SanFran). I got to learn more about the city, got in a great run, got a couple of pics along the way, and was given a goody bag at the end with snacks and a t-shirt. It is a great value, especially when you realize you get a customized, one-on-one tour. I recommend it wholeheartedly!
