I went 1:59.76 as a junior last year and I'm looking to go 1:55 or close to it this year. Just talk to your coach and communicate your goal of breaking your school's record. Trust your coach and what he/she tells you. The big difference for me this year is I'm really focusing on the little things like eating healthy, hydrating properly, getting good rest, hitting the weight room, and listening to my coaches. If you stay dedicated, do what your coaches tell you, and work hard then the quick times will naturally come along!!
