The Haspa Marathon Hamburg, Germany’s largest spring marathon, welcomes ESN as its new Official Nutrition Partner starting in 2026. As part of the partnership, ESN will ensure optimal energy and hydration for the 34,000 runners along the course and at the finish line on Sunday, April 26.
At selected aid stations, ESN will provide its isotonic HydroLoad Cherry drink as well as the proven Perfect NRGY Gels (mixed) – premium products designed to support hydration and meet the increased energy demands of long-distance running.
“A marathon pushes the body to its limits. That makes reliable race-day nutrition all the more important. As the Nutrition Partner of the Haspa Marathon Hamburg, we are proud to contribute to the performance of all participants,” says Philipp Markmann, General Manager ESN. Frank Thaleiser, Managing Director of the event organizer MHV, adds: “We are delighted to have ESN, one of the leading and highly experienced partners in the field of sports nutrition, by our side – especially in this anniversary year of the event.”
The partnership combines science-based nutrition with one of Germany’s most significant running events, creating real added value for participants, fans, and the entire running community.
Presence at the Expo
In addition to on-course product supply, ESN will present further content and activities as part of the event: An ESN Cheer Zone along the course will provide additional motivation for runners on race day. On Friday and Saturday (April 24–25), athletes can visit the ESN booth at the Marathon Hamburg Expo to learn more about the products and receive personal advice.
Beyond the Haspa Marathon Hamburg, the partnership also includes selected additional running events organized by MHV, such as the Blankeneser Heldenlauf on August 30 and the Köhlbrandbrückenlauf on October 3.
