Ran a 4:25.2 1600 at conference with splits of 62-68-68-67. The reason for the fast first lap was because the guy ahead of me is a 4:19 guy and I know I had to go with him if I wanted to take second with the competition I had. With cleaned up splits, would it be possible to go around 4:23 with 65-66-67-65 or is my race an indication of how fast I can go pretty much?
