Would a coach count 1 mile of running as part of total mileage?

I'm supposed to run 300 miles this summer but a few days ago I was only able to run 1 before it got dark out (and I'm not allowed to run when it's dark). Do you think my coach, who is pretty lenient as far as xc coaches go, would count that? I know one mile is basically nothing for xc, but I did run it fast if that helps.
