I've been trying to improve my 1500m for a while now but just cant seem to get any faster.I've tried stroke improvement,breathing,and just generally giving it all ive got...it seems that the more i pace myself the (slightly)faster i get but only by seconds.....other things tried..flip turns(these made me slower)..have i got to a personal max that i will not improve upon..if so then im gutted because i had hoped for much better
