25th O-SEE Challenge 2025

At a glance

O-SEE Challenge again in 2024 in the Zittau Mountains Nature Park with the status of a German Championship.

There is great anticipation for the XTERRA O-SEE Challenge 2025 and the associated 25th anniversary of the cult brand O-SEE Challenge, as the event will not only be another spectacular triathlon highlight, but will also once again be the venue for a German championship.

But that's not all. The anniversary event of the XTERRA O-SEE Challenge will receive a further upgrade in 2025 in addition to the already awarded status of the German Cross Triathlon Championships of the German Triathlon Union: the organization of the European Championships for the XTERRA Europe series. The European Championships will be held over the XTERRA distance (1.5/37/10km). The Zittauer Gebirge Nature Park last hosted an XTERRA European Championship in 2021.

The XTERRA O-SEE Challenge is celebrating its 25th anniversary with this year's edition of the legendary cross-triathlon event in the Zittauer Gebirge Nature Park. All 16 individual races are already fully booked. The highlight of the triathlon festival on the third weekend in August is the XTERRA European Championship, which will be held over the XTERRA distance (1.5/37/10km). The German cross-triathlon champions will also be crowned over this distance. Young athletes will also be competing for medals and World Championship starting places at Lake Olbersdorf, as the X'Kids Challenge is a stop on the global XTERRA Youth Tour for Youth A and B athletes. And the local kids compete as part of the Saxony Championships.

The organizer O-SEE Sports e.V., together with the host communities of Olbersdorf and Zittau, is looking forward to welcoming around 1,400! athletes from over 20 nations and to an exciting and inspiring competition weekend from August 15 to 17, 2025 in the Zittau Mountains Nature Park - on the most beautiful lake in Upper Lusatia, the O-SEE.
