9. G1 63 km Grüngürtelultra-LAUF

The G1 Grüngürtel Ultra, set to take place on January 17, 2027, offers runners an unforgettable urban adventure around the heart of Cologne. This 63-kilometer course follows the official G1 Rundwanderweg and provides a unique blend of flat terrain, diverse scenery, and lively atmosphere that makes it perfect for both seasoned ultrarunners and those looking to dip their toes into longer distance events.
The route winds through a mix of asphalt roads, parks, and promenades within Cologne's inner Grüngürtel, offering participants an urban running experience like no other. While the course is flat and manageable in terms of elevation gain, it remains far from easy—runners will traverse varied landscapes that keep them engaged throughout their journey.
Starting at 8:30 AM sharp, runners have a generous time limit until 7 PM to complete the distance, giving ample opportunity for pacing strategies. The race organizers provide one fixed supply station approximately halfway through with all necessary provisions, yet participants are encouraged to carry additional supplies as needed to cover roughly half of the course independently.
Attractive amenities await at both the start and finish lines, including hot soup, hearty food options, refreshing beverages, and a warm atmosphere for post-race recovery. The event also includes digital finishing certificates upon completion, adding a personal touch to your achievement.
With only 400 spots available, early registration is highly recommended when it opens on February 1, 2026, at 10 AM. This race promises not just physical challenge but an immersive experience that captures the essence of Cologne's urban landscape and running culture.
Participants should be aware that no bicycle support will be allowed during the event; all runners must carry their own gear throughout the course without assistance beyond designated supply stations. Adherence to these rules is crucial for a safe and fair race environment, with disqualification being enforced by organizers if necessary.
Join us in Cologne on January 17, 2027, for an unforgettable day of running through one of Germany's most vibrant cities.
Köln. Flat. Tough. Legendary.
