At the SJS D4/5 meet, it was explained to us that next year, the 10m acceleration zone for the 4x100m relay would disappear and become part of an expanded 30m exchange zone. At my high school, we are in the process of building our first ever all weather track. I want to make sure that the information we were given is correct before giving the change order to our track builder.

I contacted them and they were still under the impression that the exchange zone changes only applied to IAAF sanctioned meets.

I have looked at the NFHS and CIF websites and found nothing. I'm hoping that Hal Harkness could chime in on this.
