Going for "a run" has become such an integral part of "work" for me (software eng), I consider my career choices one of the main factors in my subsequently becoming a distance runner.
I began my foray into software development almost 5 years ago, and in the last 2 - not unconnectedly also my first 2 years working 100% remotely - I've run 2 half marathons (officially, several more in training), a marathon relay, a 10k, and just a couple of weeks ago my first marathon.
Bragging about this because with all the time spent training I developed an even deeper connection between the "work" (solving whatever current problem for my job) and the time I spend running. At this point I often deliberately wait to go for the run until I've really got my mind around the code/feature/bug I'm working on. Once I'm actually moving, I don't really try and actively think about it, but more often than not at some point on my run something will click, and I'll return to my desk with a clearer path forward.
