Tokyo Marathon, 2012 - The Numbers

Here are my one kilometer splits from the marathon.  In the cases where the times are listed in parentheses, I missed hitting my watch at a kilometer marker so I've averaged the time from the next marker.  Remember that to get a 3:10 I needed to hold a pace of 4.30/km.  Also, the 4.38 during the 20th kilometer was because I stopped to pee in a bush.  That took ~10-15 seconds.
