Running
I was not an athletic child. In 2015, to my surprise, I discovered I was actually pretty good at running, and I've been running marathons since shortly after I got my Ph.D. My near-term goals are to qualify for the Boston Marathon (7 f*cking seconds left to shave off my time, or I could keep running at the same speed and wait until I turn 40!), to run a marathon in every place that I've ever called home (5/7 down), and to run a half-marathon in every state in New England (5/6, harder after moving to Colorado). My longer-term goals are to run a marathon on every continent (2/7 complete) and run in all the World Marathon Majors (1/6 so far).
With frequent conference travel, I've been fortunate enough to be able to go for a run in some pretty cool places around the world. Below are videos of some of these runs, which I made by strapping a GoPro to my head. The video gets pretty bouncy sped up like this, but it can be an interesting way to tour a new city.
