While measuring a course today that starts and finishes on a track I noticed something strange about the turns on the track. Below is a picture of one of the turns.
The line is the inside of lane 1, and that other line, 30cm inside the lane 1 line, is the groove where the curb fits. Huh? So they put a curb around the track but you aren't allowed to run right next to it?
I checked, and the width of lane 1 is the same as all the other lanes, and the 400m stagger for lane 2 is the half the 400m stagger of lane 3.
This groove is actually only on one end of the track, which would indicate that it is old and the track as been relined since. But did they shift the whole track 30cm to the south when they relined it? Maybe it has something to do with changing from 440y to 400m.
Anybody want to try to make sense of this? Am I missing something?
