This summer, the university has been renovating the parking area near the track. While I was away from running, they planted new trees, but they yet haven’t filled the root areas with dirt.

Is this a liability issue?
They’ve also started to sprinkler the “grass” (which seems like synthetic wood chips for now, likely surrounding seeds?) aggressively. I was not above getting sprinkled on the way back.
I did 2 miles of intervals today, my standard 0.25 mile intervals. My target pace for each quarter mile is 1:30; I’m still a bit above that. I was hitting max HR during the intervals, so I feel pretty good about that.
Overall, I spent about 24% of my time in interval mode, and 76% of my time in recovery:(This breakdown is by pace, rather than heart rate, which, due to lags, doesn’t correlate well with the actual amount of time I spent in each cycle.)
