Lange's career is marked by numerous accolades. He was named World Sailor of the Year by World Sailing in 2016 and received the Magnus 'Mange' Olsson Prize in 2017. Additionally, he has been awarded the Olimpia de Plata multiple times by the Circle of Sports Journalists in Argentina.
Lange's family includes four children, two of whom, Yago and Klaus, have followed in his footsteps. They represented Argentina in sailing at the 2016 Rio Olympics, finishing seventh in the 49er class. Lange's father, Enrique, has been a significant influence on his career.
In October 2018, Lange underwent surgery for a hernia. Despite this setback, he continued to pursue his passion for sailing. His sporting philosophy reflects his resilience: "In a boat, you don't know what's going to happen before it's all over. Nothing is written in stone."
Lange is set to make his seventh Olympic appearance at the 2020 Games, aiming for his fourth medal. He has previously won gold in 2016 and bronze in both 2004 and 2008. His love for the Olympic experience remains strong as he prepares for Tokyo.
In March 2014, Lange came out of retirement to compete with Cecilia Carranza in the Nacra 17 class. Despite initial scepticism from coaches and friends due to his age, Lange embraced the challenge and continues to enjoy preparing for the Olympics.
Lange's journey has not been without its difficulties. On his 54th birthday in September 2015, he had 80% of his left lung removed after being diagnosed with cancer. This illness affected his training for the 2016 Olympics but also motivated him to compete in Rio de Janeiro.
Outside of sailing, Lange studied naval architecture at the University of Southampton in England. He worked with naval designer German Frers before founding Empresa Lange Internacional in 1986. The company designs boats for various classes, although Lange is currently focused on his Olympic preparations.
Lange's story is one of perseverance and dedication. As he looks forward to competing in Tokyo, his passion for sailing continues to drive him forward.
