Wowee Susan!

Years ago I used to run the stairs at a dam down the road, it was something around 105-120 steps I seem to remember, and my legs would be WRECKED if I did it even three times. Then I did some short runs when we visited Venice a couple of years ago, most of the sidewalks and almost all of the bridges are granite, that stuff is HARD.

It sounds like a beautiful place to run but really, really tough, so you should be proud of doing it at all, WITH stops to catch your breath.
