Information about SMIR Extreme 2023

SMIR Extreme will be hosted during the night of July 1st-2nd. Registration will open March 7th at 08.01 CET - first come first serve. The race starts at 21:00 pm at Utö and finishes at about 08:00 am at Arholma Nord. 

How SMIR Extreme will be run!

We will for SMIR Extreme revert to the pre-Corona set-up with only one ferry transporting the teams between islands. This means we will re-instate all cut-off times making it crucial to reach the ferry in time.

There will be a mass start on all islands with the teams starting as a large SMIR group, after which the route is free and up to the teams to decide. On most islands a Check Point must be taken before reaching the ferry. The teams can choose the fastest, shortest or most scenic route but must at all times honor the "allemansrätt" and avoid private property. 

The teams in all three classes with the shortest accumulated time finishing all 8 islands will be crowned winners of SMIR Extreme 2023!

*We just want ot explain that for SMIR Extreme we will rent a large ferry for an entire night during peak season. About 75% of the SMIR budget goes to the boat rental  and therefore the price of SMIR is not comparative to f.ex. a normal ultra-marathon, triathlon or Swimrun race. We hope for your understanding.
