Should I transfer if I wanna run a 9:30 2 mile next year?

The fact that you are asking an anonymous message board about this says something about the situation.

I really just want additional advice of whether I should transfer or not. Or somehow I can improve the situation I'm in

I transferred schools and it was the best decision I've ever made. My freshman year I ran very well with a 4:31 mile then made no improvement my sophomore year, In my opinion due to lack of quality coaching. I transferred my junior to a very well known XC and track team and immediately made improvements to a sub 4:25 mile and am back to my old self. In my case I began to drift away from my best group of friends and didn't continue to have fun at my old school. If you are leaving your best friends who you still love to be around I suggest you stay at your school and just sit down with your coach and tell him how you feel about the situation. If not, transferring is a great option. Just make sure you put the work in and do everything your coach says

Thanks man, I'll think about it

" I was able to run mile repeats consecutively at around 5:10 with 3 min rest beginning-mid season..."

The problem is not your coach. The problem is YOU don't know the difference between a workout and a race. You wasted all your races on workout days.

It is probably a little bit of both (coach and you). As noted, don't race workouts. If you would start your early season workouts running within yourself and not trying to kill them then at the end of season you would probably be fresher. As HSer you probably don't get this and won't even in college. For the most part younger runners underestimate how hard they are working and run to fast during workouts and easy runs. If you are already a senior then try this approach as to transferring. Also, as someone noted, talk to your coach as he/she probably noticed your diminishing trend as the season went on as well. So maybe workout higher volume slower pace early on building to reduced volume with faster times during the peak of your season.

Think about the school experience at the school you would like to transfer to for your senior year, and discuss this with your parents. As another poster explained, you may have a good group of friends at your current school that you will have less contact with. Also, with one year at a new school you may find it hard to fit in with new friends as you will be thinking that you will be graduated in a year. Above this, think about the academics with class offerings and new teachers and how it will help (or not) your plans to go to college next year. These are probably more important than a better coaching situation. Think about everything you would like to improve with a new school situation for one year and discuss with your parents. There's some unknowns you are dealing with here. Since it's only one year, you may be better off finishing at your current school. Meet with your coach (now) about your goals for the Fall XC season and what your summer training should be and what your were disappointed with for your progress in races last year. If you are over-training or racing in workouts, then it's up to you to recognize that and share it with the coach and modify your workouts (or your effort in workouts).

I think you already have made up your mind. Transfer and enjoy your last year of high school running. Don't waste anymore time on a program and coach that you don't like and doesn't seem to be working. But once you've changed, DON'T race your workouts or off-day runs!!!
