This year I have ran two 4:25 1600s. The first one I split 62-67-69-67. The second I just recently split 65-69-69-62. Both races were run with a pack so I didn't do much pacing I just kinda ran to win or qualify. Now that I only have one mile left this year at state I think i am capable of hitting big a pr and going 65-65-65-65. Is this possible for me or is it out of reach?
