About ÖTILLÖ Swimrun Utö

Utö is where the whole swimrun movement started and where the late night bet which became ÖTILLÖ was made.

It is an island in the southern part of the Stockholm archipelago almost 90 minutes from Stockholm. Utö has a small year-round population and a great hotel, Utö Värdshus – our home away from home.

Utö used to be a mining community in the turn of the last century where Iron ore and Lithium was mined. You can still see the remnants of this old community in the buildings around Utö Värdshus.

The nature is very typical the Stockholm Archipelago. Beautiful pine tree forests, the landscape formed by the Ice age with soft granite towards the North and broken off faces to the South and with a coast line with lots of inlets and small islands. The land is constant up and down, technical trails and incredible views. The island of Utö is connected with the island of Ålö to the South where you feel alone. If you get a chance to run on the East coast of the island going North from Utö Värdshus you are up for one of our favorite runs in the world.

In the end of May you can feel summer coming on; flowers are blooming, the grass is green and the trees are coming to life after a long winter.

Our images that we post from the race are free to use for you as racers but not allowed for commercial use to promote other products or events.

Weather at Utö

September is a beautiful month in the Stockholm Archipelago. The leaves become an explosion of color, the water is a lot warmer than in May (when we usually have the race) and we can have anything from a warm, sunny day to a cold and wet storm. As the race courses are super intense we do not expect you to be cold.
Like everywhere we can have wind, rain and un-seasonably cold. Make sure you bring clothes to handle this. The water in the Baltic has very low salinity, some teams will even race without swim goggles.

Spectators, friends and families at Utö

We welcome all spectators, friends and families to participate in our events. During the Covid-19 Pandemic you need to observe our ÖTILLÖ Covid-19 Safety Management Plan.

We ask you to make sure you avoid creating a crowd and to keeping safe distance to others. In the event area at the finish line we will only allow racers.

The races are great to follow as a spectator. All courses are very easily accessible from land and our recommendation is that you rent a bike in the harbour on Utö. That way you can ride around and look at the teams. Make sure to ride safely as you are on open roads, even though they have li­ttle traffic.
You could have lunch at Båtshaket on Ålö where all the teams will pass around lunch-time in the World Series race. Print the race map found on the web page and you will see where to go.
NOTE: you may not assist any teams unless if it is a medical emergency. Any other assistance will result in disqualification of the team.

ÖTILLÖ Merchandise

Our partners will be in the event area at the finish line with products on-site.

Swimrun rescue

As a swimrunner you are responsible for your team mate and for others around you. It is your obligation to know how to rescue someone out of the water, how to do CPR and how to use your Mandatory pressure bandage if someone has a bad cut. Here are some good films for you to watch.


Swimming induced pulmonary oedema (SIPE) is a condition which has gained attention in recent years. In short, due to somewhat unclear mechanism, fluid collects in the lungs, compromising the transfer of oxygen from the lungs to the bloodstream. This results in the following symptoms;

  • Shortness of breath
  • Decreased oxygen saturation (which has to be measured with medical instruments)
  • Cough, sometimes with blood

There is ongoing research in the subject, and as the knowledge increases, we will hopefully learn how to better prevent, diagnose and treat the condition.

The current research suggests that the condition terminates in less than 48h. Often it’s enough to stop the activity, remove/open up the wetsuit and get warm. In some cases, oxygen therapy is needed. It’s not fully understood why the condition arises.

There are yet no studies evaluating the long-term effects of SIPE. There is evidence that susceptible individuals may have recurrent episodes of SIPE. There are some medications that may help to prevent recurrent episodes.

If you experience the above symptoms, we recommend stopping the activity and contacting race marshals. If you encounter symptoms during a training session, we recommend seeking medical attention since there are other medical conditions which can manifest in the same way.

Train smart, race hard and take care of yourself and your partner!

Force Majeure

Neither the participant nor the race organizer shall be held responsible for a force majeure event. Force majeure means any event which is unforeseen and beyond the reasonable control of either party including but not limited to the following: Act of God, adverse weather, inevitable accident, failure or shortage of power supplies, fire, flood, epidemic, earthquake, explosion, lightning, war or armed conflict, embargo, government or regulatory action or decree, riot or civil disturbance, strike, lock-outs, or other industrial action, terrorist action, failure or delay of common carrier or impairment or lack of adequate transportation facilities.

If by reason of any force majeure event the race organizer is delayed in, or prevented from, performing any of the obligations with regards to staging the race, no loss or damage shall be claimed by the participant by reason thereof.
