The Hy-Vee Triathlon (now known as the Des Moines Triathlon) was an Olympic-distance triathlon race held in Des Moines, Iowa, USA. From 2011 to 2014, the race served as the World Triathlon Corporation's 5150 Series U.S. Championships.[1] Previously, it was part of the ITU Triathlon World Cup series from 2008 to 2010.[2] The annual triathlon event attracted many of the top professional triathletes in the world due, in part, to having the largest prize purse awarded for Olympic-distance races in the sport[3] (and from 2008 to 2012, the largest in the sport overall[4][5]). In addition to professional triathletes, the triathlon event features competition among amateur athletes as well.
