Saucony Elite 50 #1 Alexa Efraimson (Camas WA) was declared ineligible for the rest of the HS season by the Washington Interscholastic Athletic Association recently for her participation in the Bill Dellinger Invitational on October 5th. Alexa ran unattached and won the race against an elite collegiate field with a time of 16:35.
Update that came in as this article was being drafted: Alexa and her parents appealed the ruling and she was reinstated on Thursday, October 17th, and will be allowed to compete.
Statement from Alexa: "After a few meetings, my parents and I have appealed my eligibility and I have been reinstated, so I can compete now!"
The WIAA has a guideline for competing on or against a professional or college team, however, it is not clear how this pertains to individuals.
