look, if you ever ran on a particularly cool day outdoors in the south in february, we would call that chilly, and it would probably be balmy by northern standards. it might be 0 out. or 15 and snowing. the track might literally be under feet of snow.
also, a lot of schools use indoor, at least initially, more like competitive practice.
that being said, i think you have somewhat of a point where i think college kids would benefit from purposeful downtime or multiple peaking, where, say, a soccer player starts back up in january and not november for TF, ditto XC, maybe even some time off in march after indoor. i believe in rest. i don't think the human body is designed to be training hard and competing from july or august until may or june.
and that's even acknowledging that in reality most college runners are "rotated" and don't run every meet, or maybe have relay duty.
the comparison i would make is to pro soccer. in europe a guy who plays in the world cup or euros, and misses their vacation time from the summer, might literally be told to go on vacation a couple weeks, start training camp later, and be brought into the lineup later in september, knowing they will still be able to play 30-40 games after resting. TF to me can have a workhorse mentality and athletes can be disposable.
