Notes
First 23 miles of the Chicago Marathon. Had planned on a DNF once I got to mile 23, since I was starting to feel weak at about mile 21 and since I had walked the entire mile from 22-23. Stopped the Garmin timer at mile 23, walked to the next Runner Dropout station, where I was told that I would have to wait around a while to get shuttled back to the finish area, so I decided to walk the remainder of the race.
