I think that is very fast.
running
in the US, each level of school is denoted as a grade. so, the seventh level is seventh grade and someone attending this level of school is called a seventh grader.
My fastest miles were in late high school when I could do them in roughly 5 min (since then I've gotten slower but my endurance has probably more than tripled). 6:14 is way faster than I was going at your age. In a couple of years hopefully you'll be blazing. I used to run the 400, 1500, and 3000 and it was nothing but good times. Good luck.
do you guys think a mile time of 6:14 for a 7th grader is good? Last trimester at my school, i got 6:42
