Is it possible that Ironman Lake Placid is getting harder? The course hasn't changed much between 2004 and 2009, but the average finish times by age group certainly have. Notably, the average overall finish time has slipped from 12:46 to 13:08. Some of that difference may be explained by the roughly 20% increase in number of starters. Any way you look at it, IMLP is one tough course.
