229 teams were at the start of the main event of 38 km trail running
and 5.2 km open water swimming.

The first couple swims are typically busy but the field spreads out fast.

Swedes Daniel Hansson and Fredrik Axegård (Team Swedish Armed Forces) were among the favorites here but in the end finished 3rd.

Swedes Michelle Nyström and Erik Fridolf (Team Garmin) are likely glad to have great traction here. They finished 3rd in the mixed division.

Some teams were dressed warmer than others for the conditions in Utö.

Athletes had to tackle 19 different swim sections with the longest swim being 600 meters.

The countryside is impressive but the focus was likely on the task ahead. Team Puppy TS with mom and daughter Nordblom on the way to 5th place.

The aid stations are a very welcome sight for all athletes.

This race course has a lot of character and entering this building is like opening a Cracker Jack box. You never know what you get.

The race champions Pontus Lindberg and George Bjälkemo had a superb day, and these two professional triathletes may soon focus fully on Swimrun.

Swim my friends swim.

Or walk.
