Notice how many people were watching. That tells you all you need to know about the popularity of distance events.
What will I do if Jager breaks the WR? I will do the same thing I did about the 1500 gold. I will do my own workout on Friday and ignore it like just about everyone else. Morris in the PV may be interesting as may Schippers vs Thompson in the 100m, and if so, I will watch the video replay on watchathletics. But a SC is not something I or just about anyone else cares about.
