I'm currently re-listening to all of the episodes, and I am currently on episode 14, where you talk about how cubers enjoy celebrating beating their own accomplishments, and other cubers do a great job of celebrating other people's personal accomplishments as well. Kit and Andrew were talking about the running community, and how running may or may not have that same atmosphere, so I figured that I would share a little bit.
I got done with my cross-country season a couple months ago, and I agree with Kit when he says that cross-country has more of a sense of celebrating personal achievements than track & field does, although at my school, both do a very good job. I have the same coach for CC as well as track, and she does an amazing job of creating an amazing team atmosphere, and celebrating everybody's accomplishments. The practice after a meet for CC or track, she reads a list of everybody's PRs, and it feels really good to have that recognition of your achievement.
As far as a sport overall, I think that track and field as well as swimming are very similar to cubing in that they have a large variety of events, and people often specialize in certain ones. I am not a swimmer, but for example, in track, I specialize in the 400, high jump, and triple jump. In cubing, you could compare that to specializing in 4x4, pyraminx, and skewb. The 400 is a short/middle distance event, similar to 4x4, and high jump and triple jump are field events that are often regarded as "side events," similar to how pyra, mega, skewb, square-1, and clock are considered side events in cubing. (Running blindfolded or in the fewest strides would be tough, though.

)
If any other runners have anything to add, I would love to hear it!
