A postcard arrived in the mail:
1998 A.L.A. Chicago Distance Classic 20K Race
Time 2:25:21 Pace 11:44
You finished 3117 out of 3200 total finishers.
You finished 1948 out of 1984 Males.
You finished 343 out of 346 Males age 25 to 29.
(And if you're wondering why the time above differs from my self-reported time, it's because I started my stopwatch when I crossed the starting line which was about a minute and a half after the official start time.)
