The average splits and finish times illustrate just how tough the course was, especially the marathon, in 2011.
Not a single age group averaged less than 12:30 for the event. Very rare.
Taking it the next level, here's the detail: splits, finishers and DNFs by Age Group. If you beat one or more of the split times in your age group, consider your race a big success.
