Career
Olesen has also been training throughout most of his sporting career for Kaløvig Bådelaug Yacht Club in Århus. Olesen made his official debut at the 2004 Summer Olympics in Athens, where he paired up with Nicklas Holm in the Star class. On August 16, 2004, Olesen had almost been injured and charged in an automobile accident, when his partner Holm struck and killed a British pedestrian while speeding in his car on the way to witness the Danish handball team"s prelim match.
Being overshadowed and cleared by the accident charges, the Danish duo recorded a Netto score of 83 points to establish a satisfying ninth-place finish in a fleet of seventeen boats, trailing behind Bermuda (led by four-time Olympian Peter Bromby) by a single mark.
Eight years after competing in his last Olympics, Olesen qualified as a 38-year-old veteran and a crew member for the Danish squad in the Star class at the 2012 Summer Olympics in London by placing third and receiving a berth from the World Championships in Hyères, France.
