Wow this is crazy this happened to me as well, i am a high school senior who was looking to place well for states with a solid PR but I bombed it because iIwas forced to taper. Now my college scholarship is screwed (have track left)
Did you taper, if so how hard did you work before you tapered because tapering only works well if you are on the verge of burning out. I have found out that tapering is the last thing you should do and most HS programs end up tapering.
