Ludwig failed to qualify for the 2010 Winter Olympics in Vancouver and the 2014 Winter Olympics in Sochi. At the 2018 Winter Olympics, held in Pyeongchang, South Korea, Ludwig won the bronze medal in the men's singles luge. Ludwig's teammate Felix Loch was the defending champion and favourite to win. He was in the lead until his final run, when he made a mistake, finishing in fifth place. Lugwig was also one of the gold-medal winners in the team relay luge, along with his teammates Natalie Geisenberger, Tobias Wendl, and Tobias Arlt. Lugwig said "The whole story is very special for me, I was fighting, fighting, fighting and now I made it and get two medals".
