My PR is a 17:30
the distance which you ran might also be helpful, must have been a pretty short race.
His race was 3 miles
For high school the races usually are 5ks or three miles
college teams will run 10ks
oh ok, my brother is a very serious cross country runner, his races seem to vary from 8 to 12km depending on the exact event.
that’s not bad. i was injured every year for various reason so my times sucked. i think my pr was like 20:10 or something like that. that was with a fractured foot. 
I ran XC as a freshman, thankfully our school added fall soccer for the balance of my HS career. I think Bill Cosby summed up XC the best with something like this:
“XC is not a good spectator sport. Why would you want to watch a race where the contestants run 2 1/2 miles just so they can throw up?”
