Claus-Henning Schulke, a 60-year-old Berlin construction engineer and amateur athlete, has become a legendary figure in the marathon world. Known as 'Bottle Claus', Schulke has been providing water bottles to elite runners during the Berlin marathon for 30 years. His crucial role in helping athletes achieve their goals has earned him a reputation as a vital part of the competition. Schulke's dedication and expertise have made him a sought-after figure, with many top runners vying for his support.
Schulke's impressive track record includes helping five runners finish first at the Berlin marathon, including Eliud Kipchoge, who broke the marathon world record in 2018 with Schulke's assistance. Kipchoge has praised Schulke, calling him "still my hero up until now" in 2022. Schulke's contributions to Kipchoge's success have been significant, with the Kenyan athlete acknowledging the importance of Schulke's role in his victories. Schulke's work with Kipchoge has spanned several years, with the pair enjoying a successful partnership.
Schulke's impact on the marathon world extends beyond his work with Kipchoge. He has also helped other top athletes, including Sabastian Sawe, who won on his Berlin debut in 2025. Sawe, who ran 1:59:30 in London in 2026, becoming the first man to break through the mythical two-hour barrier, had been hoping to better that mark in Berlin this year. However, he was forced to pull out due to injury, leaving Schulke to support another contender.
Schulke's role as 'Bottle Claus' involves more than just handing over water bottles. He must make quick and precise handoffs, often at high speeds, while navigating the crowded course. A perfectly executed handover can save runners around two to three seconds, which can be the difference between a world record or a near miss. Schulke's expertise and focus are essential in these high-pressure situations.
Schulke's passion for sports extends beyond his work as 'Bottle Claus'. He is a civil engineer who helped oversee the construction of Berlin's 680 million euro ($775 million) Humbolt Forum. Schulke is also an accomplished athlete in his own right, having completed the Hawaii Iron Man six times and running a 2:34 marathon personal best at just 19. His love of extreme sports has taken him to new heights, including completing the 2026's Race Across America.
Schulke's admiration for Eliud Kipchoge extends beyond his athletic achievements. Schulke has spoken about the inspiration he draws from Kipchoge's attitude and approach to life. Schulke has credited Kipchoge with helping him overcome "mental weakness" during his cycling journey across America. The two have developed a strong bond, with Schulke cherishing a wristband given to him by Kipchoge that reads "no human is limited".
As the 52nd Berlin Marathon takes place on Sunday, September 27, 2026, Schulke will be on hand to support another top contender. Despite his stellar record, Schulke admits to "sleepless nights" before the big race, highlighting the pressure and responsibility he feels in his role. With his expertise and dedication, Schulke will undoubtedly play a crucial part in the competition, continuing his legacy as 'Bottle Claus'.
