The younger of the two brothers, Michael Raelert won the 2005 Alpen-Triathlon in Schliersee with a new course record over the Olympic distance to secure himself the German national champion title. Three years later he repeated his victory in Schliersee. In 2009 Michael moved over to the half Ironman distance.
In November 2009 he took his first international title on this distance, winning the World Championships in Clearwater (Florida) with a new race record. In 2010 Michael remained unbeaten over the Ironman 70.3 distance. In August 2010 he crowned this series of victories at the Ironman 70.3 European Championships in Wiesbaden, setting a new course record on his way to the title.
Three months later, the European Champion defended his title in Clearwater with an impressive race and claimed the title as the Ironman 70.3 World Champion again. It was a victory that secured his place in the triathlon history books.
Michael made his Ironman debut in 2012 at Ironman Regensburg and once again took the title at the Ironman 70.3 European Championships in Wiesbaden in the same year – with a new course record. After a setback from injury followed by a lengthy period of recovery in 2013 and 2014, Michael now has 20 Ironman 70.3 titles to his name.
