In 13 or 26 miles, anything could happen to screw the race up for a single runner. I recall that Wesley Korir during the 2012 Boston Marathon was completely overwhelmed from the heat and ran something like 2:20+. Hall suffered a similar fate during the 2014 Boston Marathon when he just faded horribly during the race.
A half marathon is not as unpredictable as the marathon. Not even close. A half marathon is easily fixable. The marathon is unpredictable because of fuel issues. There are no fuel issues in a race as short as a half. High schoolers do half marathons as long runs at planned paces every week.
