The 2227 finishers of 2012 Ironman Louisville appear to have tackled the harshest conditions of the last four years, with a 14% DNS rate, an incredibly high 14% DNF rate, and the highest average time since 2009: 13:41. If the conditions in the 2010 race were considered highly extreme, 2012 may have even been worse (though an extraordinarily high number of flat tires may have been caused by course sabotage). Still, Ironman Louisville remains ranked near the top of our Toughest Ironman Triathlon ratings.
