What racers and reviewers say
- triathlon+ / tri-mag RenncheckRaced 2026 · survey · Positive
Community survey gave 4.6 of 5 stars. Respondents all said they would return, praising near-flawless organisation, smooth transitions and atmosphere in all three sports. Criticisms were congestion on the bike where half and full fields mix and aid-station nutrition.
- Soester AnzeigerRaced 2026 · article · Positive
Local report on a podium finisher (8:22 total). Sea was near-glassy at about 19 °C (66 °F) with light wind and mixed sun/cloud, roughly 1,600 starters. Swim ~1:10, bike 4:21 and a 2:47 marathon showing fast conditions.
“Nach dieser Leistung bin ich auf jeden Fall super motiviert.”
- Wikipedia (de) OstseemanRaced 2025 · article · Mixed
Reference summary: only German full-distance race with entirely open-sea swim, first held 2002, ~1,800 starters in 2025. The 2025 edition faced high waves, heavy rain and strong wind; later 2026 edition matched a course record near 8:05.
- Mission Triathlon (Lotta)blog · Mixed
Half-distance report in cold wet weather: choppy ~20 °C (68 °F) sea, two 45 km (28 mi) bike loops with many small climbs and alternating 25 km (15.5 mi)/h (16 mph) headwinds and fast tailwinds, then a well-supported three-lap run. Volunteers were friendly; verdict was imperfect day but special, recommended only for weatherproof beginners.
“Es war kein perfekter Renntag – aber genau deshalb ein ganz besonderer.”
- Ben Triathlet blogRaced 2019 · blog · Positive
Finished 9:44 (3rd AG). Jellyfish and crowded swim laps as half-distance started 20 minutes later; bike congested and crash-prone with tight pylons and unclear markings; run crowd was a highlight. Liked hotel on the course, found pasta party bland and would rank it above Roth for atmosphere.
“Von der Stimmung und vom Streckenverlauf würde ich den OstseeMan jederzeit vorziehen.”
