hey man. Just want to say I totally feel you on this one. I am also at the back of the pack, but at a D III school. My times aren't comparable to those most people here ran in high school. I am not going to win any competitions, and my coaches are fairly incompetent. I go to a really academic school, though, so know that none of us prioritize running. If they started being hardasses, we'd all quit. So overall they're pretty laissez-faire. They offer a few kids monitoring but for most of us, if we don't actively try to get their attention, they give very little guidance.
I have found this works really well for me. For my freshman and sophomore years (I'm a rising senior), I frequently asked them for advice and guidance. Then I started to notice that they weren't producing good results for either me or anyone else. Our best runner, someone who was an all-american indoors, did soccer in the fall. Everyone else sees to get injured, peak at the wrong time, or simply not perform to their potential. Obviously we don't really know, but our head coach is often very inattentive to details so he misses a lot, details that I think we who run as a group each day notice.
I have thought about quitting as well. Frustrations with the coaching are secondary, for me, to the lack of time I have for other things and some unrelated frustrations with running as a whole. But I've decided to stick it out,for a few reasons. Running on the team provides structure to my life. Exercise makes me feel good. And, in an important way, I value the team and it members. They are my best friends.
So I run for my own enjoyment. I don't particularly care about how well the team does (which is good because we just got in last at our very uncompetitive conference anyway). I also do not seek out the coaches any more than absolutely necessary, and they reciprocate by basically leaving me to my own devices. They plan Tuesday and Thursday workouts and that's about it. You can probably create a similarly inattentive relationship with your own coach, taking increasing charge of your own training. My advice is to not quit the team because you'll lose a lot, but rather to change your expectations of what the team can provide you. Take running seriously: your coach, not so much.
P.S. you don't by any chance run at Liberty do you? If so, your post name was perhaps an undiplomatic choice.
