When I was in grad school, I started a bit of a game with myself, keeping track of countries, states, and provinces where I went running. The rules of this game are simple: a country, a state, or a province gets added to this collection if I go running there, and run at least 1 mile. The current collection of countries and states, for the most part accumulated over the years of the Ph.D. program, is here:
My most prized item in the current collection is China, where I ran a few kilometers in the Olympic Complex one smoggy morning while visiting for the ACM MobiCom’09. Expanding the collection is on the to-do list for the next few years.
