Prague is a gorgeous, interesting city, but it is not a good city for running. First, there´s the cold weather and snow, when all but the hardiest souls have to head indoors to a treadmill. Then there are the cobblestones and the hills. When I finally did attempt a run outside, I discovered that those Vinohrady hills, which looked gently rolling from my car window, felt like the streets of San Francisco when I tried running on them.
