Welcome to the ÖTILLÖ World Series 1000 Lakes

The place to be in the autumn

Date TBD

This ÖTILLÖ Swimrun World Series race course is a point-to-point race. The course is fast with lots of transitions between land and water. In some places you will be alone and in others you will be cheered by several hundred that have come out for you.

Race description

This swimrun race course is fast and spectacular! Not only do you need to be able to move fast along never-ending forest trails, you also need to be strong in the water with many swim sections and almost 25% swimming. The water is usually calm and flat so think of it as a giant pool. 10 swim sections means lots of transitions, be fast in and out of water to gain time. The start is in the Manor of Wesenberg and the finish is next to the castle in Rheinsberg. Get ready to embark on a new adventure, through mystical forests and in untouched lakes.

About ÖTILLÖ Swimrun 1000 Lakes

ÖTILLÖ Swimrun 1000 Lakes is only 70 km from Berlin and offers incredible opportunities where you can combine swimrun and a city get-away. The Mecklenburger Seenplatte is special, it is very rural, it is riddled with pristine lakes with drinking-quality water and it is full of beech forests. This makes the location extremely graphic, while running on the beautiful, fast sand trails everything around you is in a vertical plane with tree trunks reaching for the sky! You feel as if you are in almost virgin nature. The location is different than anything we expected.

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.
