Here's me near the end of the San Francisco Marathon. I look rather happy...probably because I have no more hills to run up. I had no idea there were so many hills in the City.
I will spare you the boring details of how difficult it was to get to San Francisco. The morale of the story is: If you are ever offered a trip to anywhere if you will take a later flight to San Francisco, take the trip to anywhere (and the later flight).
Things to do in San Francisco after running a marathon:
1) Look at the cable cars outside your hotel room.
2) Kill the pain with a martini served in a wooden cask.
