Multi Island Run 


Welcome to SMIR

SMIR is a world unique experience in the outer Stockholm archipelago. But it is also an ultra marathon. Run in teams of two. Across 8 of the bigger islands. All in one day!


The amazing story about The Original 10

On July 27th 2017, a hand-picked group of brave runners set out on an amazing journey. They had one goal. To attempt the crazy idea of running the entire Stockholm archipelago in one day. Forever legends, the Original 10 proved it could be done!

They all count and the smart Challenge Points system rewards you and your team for who you are, and what you have done.
