Running to see places is great in that it combines both exercise with tourism, and one can see sights more in depth from the ground rather than from the second story of a double decker bus. Yes, I do arrive at somewhat crowded places wearing bright synthetic shirts and sweating profusely, but it also creates a nice halo of space around me at all times as most people don't like to touch visibly sweaty people.
One of my fondest memories of being there in 2006 was being on the famous bridge with my good friend Rachel. We waited and waited for a gap in the crowds of tourists to get a shot of us, and just like that, the crowds parted and we got a photo. This time, I was much more lonely, and it took no time at all since there was maybe a quarter of the amount of tourists which would undoubtedly arrive in a month's time.
