Congratulations to the 1134 triathletes who completed the inaugural Ironman Wales triathlon in an average time of 13:02. Any race over the 13 hour mark is one of the toughest in the world, and the 12% DNF rate, also one of the highest of all ironman events, proves the point.
With two races in the United Kingdom, each known for difficulty (UK average finish time in 2010 was 13:01, nearly identical to 2011 Wales, though in 2011 UK was much faster at 12:35), we compared the two by age group to see how comparable the courses may be.
