Swimming in a canal without the need to sight to track your path helps. With the shoreline or midline course markers as a guide, there is minimal need to sight. “For me, this is the most fascinating part of the race. Twenty thousand people come up along the canal creating a great festival atmosphere as the sun is rising. It’s absolutely magic,” Walchshofer said.
Germany’s Michael Prufert swam a 43:35 in 1997 here, while fellow German Janina-Kristin Gotz holds the women’s swim time in 47:24 (2009).
