About ÖTILLÖ, The Swimrun World Championship

ÖTILLÖ is the original swimrun race, it is The Swimrun World Championship. To finish the ÖTILLÖ course before dusk, the competitors must be very fit and they must be very fast in and out of the water as there are 46 transitions. The teams swim between the 24 islands and run over them. The total distance is 70 kilometres of which 9 km are open-water swimming and 61 km are trail-running.

The start at Sandhamn is mythical and the finish at Utö Värdshus on Utö is like coming to Nirvana. There are spectator spots and food stations at some well-known restaurants on the islands along the way. There are safety boats, medical staff and race marshalls on the course to try to guarantee everyones safety.

The Baltic is the life lung of the Stockholm Archipelago and we need to raise awareness about protecting it.

ÖtillÖ general race information
Race rules

Each athlete participating in an ÖTILLÖ Swimrun (World Series, Sprint & Experience race) must know, understand and follow all the competition rules. Please read the ÖTILLÖ Standard Swimrun rules.

Safety measures
  • Take care of each other; it is a long and tough course.
  • We have safety boats and are trying to do our best to cover the course.
  • All racers have to help another racer in an emergency.
  • We have several medic teams on the course.
  • Communicate with race officials when help needed.
  • If you abandon the race you must communicate with race officials as soon as possible and return the timing chip at the finish area.
  • We suggest that you do not use a tow rope when running in difficult terrain.
Cups at ÖTILLÖ Races

As we no longer have restrictions regarding cups we will go back to our “old” behavior. We will no longer supply cups at the energy stations. You need to bring your own collapsible cup or soft flask that we will fill. One cup or soft flask per person is included in the mandatory equipment.

We will have cups and soft flasks to sell at the events if you do not have one with you.

Race course

If the race organization believe there is a danger for the racers or the organization based on weather or other conditions, the course can be changed the day before or even in the middle of the race. Safety is our priority.


You must have a valid personal insurance for racing in Swimrun. If you do not have one you can purchase it for the race or for the whole season, valid in all the races listed. It is an insurance that will repay your entry fee and travel costs if you have to withdraw prior to the race due to an accident or illness (you have to have a doctor’s certificate).
Read more and buy your insurance here.

ÖTILLÖ Qualification

At all the ÖTILLÖ World Series events from the latest World Championship to the next there are nine (9) direct qualification spots available, 63 in total. These direct qualification spots are only given to teams where no racer in the team already has a spot.

If a spot is declined it rolls down to the next team. You do not have to be at the award ceremony and you do not have to pay on-site to get your spot. The direct qualification spots are distributed to 4 men, 3 mixed and 2 women teams at each event. This is based on the historical amount of teams per category to make the probability rate as equal as possible.

ÖTILLÖ Merchandise

As you might know we have some ÖTILLÖ branded goods. These can be found on our website

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.
