Race description

We have taken over a West Coast Swimrun tradition since 2012 and made something new. From 2022 this event will be on a new racecourse. This World Series is a full-throttle event. A high-speed sightseeing of a unique environment. The course has lots of swims, the runs are mixture of fast ”park-paths” and real island hopping. It is constant up and down, in and out. The islands have lots of people on them at this time of the year so you will all be heroes. You are up for a mega treat.

This is the last chance to qualify for ÖTILLÖ, The Swimrun World Championship.

About ÖTILLÖ Swimrun Gothenburg

We are very proud to continue to build on the strong West Coast swimrun tradition.

ÖTILLÖ Swimrun Gothenburg is just off the mainland with local ferries servicing the islands and archipelago of Styrsö, Donsö and Brännö several times per hour. This race is super accessible and the the race environment is unique.

The islands are beautiful granite islands with small communities everywhere; the summer tradition, the ocean and the friendly smiles are ever present. The fishing community is still active.

In early August it is the height of the summer season and there will be lots of spectators. To have all three distances on the same day makes for a perfect swimrun party. This is a real celebration of the Swedish summer.

Travel to Gothenburg

Gothenburg is Swedens second largest city. You can easily reach Gothenburg by plane, train and by car.

In Gothenburg most ferries to the Race area at Styrsö Bratten leave from Saltholmen. The easiest way to see the time tables and to pay for your ferry ticket is by downloading the Västtrafik To Go app. The easiest way to buy a ticket is in a ticket machine on the boat dock or in the app Västtrafik To Go. But it is also possible to buy a ticket with your debit/credit card on most boats. We strongly suggest that you go to Saltholmen with public transportation as it is hard to find parking there.

You can also take the ferries from Stenpiren, located in the city center here.

Please see the detailed ferry schedules here: Ferry Plan Otillo Swimrun Styrso 2024 (tba)

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.
