About ÖTILLÖ Swimrun Engadin

This destination is like a fairy tale. It is the race that launched the international swimrun movement in 2014 as the first race ever outside of Sweden. A unique race in a unique place, hosted in the fantastic Engadin Valley in Switzerland.

The well-known St Moritz is in one end of the valley and in the other you find the mountain communities of Silvaplana, Sils and Maloja. The valley has several pristine mountain lakes on the valley floor and also some at altitude, up in the mountains.

In July the flowers are in full bloom, the glaciers hang over the valleys and the lakes have warmed up. The valley floor is at 1700 metres which means that you are at altitude. The weather in the mountains during this period can be anything from a nice summer day to a cold, hard day out. Be mentally prepared for the worst and enjoy the best.

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 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.
