My ankle is feeling much better (almost no pain in the morning) but I decided to still take it easy. I did a map snippet exercise at a walking pace. Although I threw in two short bouts of jogging to see how it felt during and after. There were no side effects so I think I can start running again for short distances.
The map snippet exercise means I drew circles at random and numbered them (for orientation to north). Then I cut them out and put them in a pile. When I got to campus, I pulled one out randomly and had to determine where it was on the map (I did this from memory, no map). When I get there, I pull out the next snippet. This is a good exercise on an area I know well and forces me to pay attention to every detail in the circle. It's especially hard in areas that all look alike (like edges of parking lots). A compass would have been helpful on one or two of the snippets. Here is a picture of some of the map snippets I went to, as an example:
