From the course certifier:
"John,
I verified the turnaround and overrun distance, per my mistype on the
Chicago Distance Classic Half marathon certification turnaround point
description, last night Monday 08/11/2008 around 7:15 PM.
Here are the results of my finding:
The turnaround point was extended approximately ~.1668 of a mile (~880
feet = ~268 meters) per my mistype of the turnaround point on the
course description. It should have read: Turn around: Lakefront Trail
(LFT), 40' 7'' South of 4th light pole (W) NORTH of N.E. corner of
Science Dr. and Lakeshore Drive. With that, the complete half
marathon distance of 13.1094 miles was extended approximately ~.1668
of a mile to ~13.2762 miles.
As the error elongated the course and did not shorten it, there should
not be a need to remove the course from the certified courses list
and replace it with a new course and number. I will make the
correction on the course map description and send it forward to USAT&F
(copied on this email: Jay Wight) to be filed as the correct certified
course so that if this course is run in the future it can be laid out
correctly.
I apologize for this mistype and any problems it has caused. I take
full responsibility that my mistype of the turnaround point
description caused misplacement by course officials of the turnaround
point on race day and extended the length of the race.
Please let me know if there is any other information you need from me,
or anything else I can help with to clarify further.
My sincerest apologies,
Neyl A Marquez"
We are now working with the Marathon and the timers to see how to best handle the qualifying times.
