OstseeMan Triathlon Glücksburg

Germany's Only True Ironman Triathlon

The OstseeMan in Glücksburg on the Flensburg Fjord is a unique event in the German triathlon scene. It is the only triathlon in Germany contested over the full long distance with open-water swimming in the sea: 3.8 km swimming, 180 km cycling, and 42.195 km running — exactly the Ironman distance. The organizers themselves call the region the "Hawaii of the North" for good reason.

Multiple Competitions for Every Level

In addition to the long distance, the OstseeMan offers three other formats:

• Middle Distance — 1.9 km swimming, 90 km cycling, 21.1 km running, also the state championship for the Schleswig-Holstein Triathlon Association (SHTU)
• Charity Run — Fun run for a good cause
• OstseeKids — Triathlon competition specifically for children

Both distances can also be completed as a relay (swimming / cycling / running divided among three athletes).

Sandwig Beach — Transition Zone and Festival Mile

The venue is Sandwig beach in Glücksburg. This is where the transition zone is located, as well as the start and finish. The entire town in the Schleswig-Flensburg district transforms into a festival mile on the event weekend: spectators line the course, live music, food and drink, and family entertainment accompany the competitions. A fireworks display on the beach concludes the event.

1,500 Athletes from 15 Nations

The OstseeMan annually attracts around 1,500 athletes from 15 nations to the fjord. The middle distance is the largest field with approximately 800 individual starters and 450 relay participants, while the long distance remains the prestigious main race for around 200 individual athletes plus 150 relays. Both events have been mandatory dates in the calendars of North German triathletes for years.

Trees Instead of Trophies — Sustainability as a Trademark

The OstseeMan has focused on sustainability for years. A tree is planted for every registration — most recently, 100 saplings were planted in Süderlügum, each symbolically linked to registrations from the previous year. Main partner sebamed underscores its profile as a sports and lifestyle event.
