At the World Championships, Martikán had an uninterrupted medal run in the individual C1 event between 1995 and 2010. The 2011 ICF Canoe Slalom World Championships saw him finish outside the medals for the first time in an Olympic or World Championship individual race in his career. Ironically, this failure came in front of a home crowd on the Čunovo course near Bratislava. However, he managed to win gold in the team event with his Slovak teammates to prolong his medal run. He won another six gold medals in the C1 team event between 2013 and 2019, making it 17 straight World Championships with a medal.
