Triathlon wierdness

It seems wierd to me to read in the paper the other day that the Kiwi blokes at the world triathlon champs buttoned off and one even pulled out in the run because in 2 weeks they have to race for Olympic places at Beijing. Wierd to timetable the trial 2 weeks after the worlds! Why not make the worlds a qualifying race? Sure, it is good to qualify on the Olympic course, but it demeans the world champs. What would I know I suppose?
