But heat makes for dreadful running conditions. I was pretty well trained, but I ended up running 3:43:55, or a tad slower than in Chicago 2007 (also record heat, with the race stopped around the four-hour mark) and Chicago 2009 (hot, though not that hot---but I was somewhat undertrained). Which makes this a personal worst. Oh well, stuff happens. And it was a pretty rough day---reports claimed that 2100 runners, or about 10%, were seeking some form of medical attention during or after the race which is a much higher proportion than under normal conditions.
The chart below is an updated version of a chart which had appeared on my running page before. I regrouped my prior Bostons (2007, 2009 and 2010) on the left, and the Chicago runs 2007 and 2009 on the right---and each with the current Boston marathon.
So compared to the prior Boston races, I did indeed relatively poorly. Starting slower, and slowing down even more leading to about 1:45 for the first half and 1:58 for the second. Compared to the two poor Chicago races (put of the six times I have ran that race), things are not quite as bad as at least I didn't peak at over 10 min/mile. Weather will always remain a challenge. The previous marathon (which was last fall's Fox Valley 2011) was unseasonally cold and wet---making for a time fast enough to get me back to Boston. I am registered again for this one, so we will see what September brings this year.
