We have shown you pictures from various unique SwimRun events, but here now is the official video from the 2015 ÖTILLÖ Swim Run World Championships. 65km of running and 10km of swimming with about 50 transitions - captured in just 5 minutes.
Getting in and out of the water at ÖTILLÖ is challenging even for very experienced athletes.
This year strong winds added another challenging factor to this difficult event.
All kinds of skills are needed and patient teamwork is ranked highly among them.
There was plenty of running, but some sections were particularly challenging.
