Welcome to ÖTILLÖ Sprint Catalina

Our tribute to America and to the cradle of endurance sports


This ÖTILLÖ Swimrun Sprint has everything. Fast-paced fire roads, epic swims, a big nature experience and a fantastic atmosphere. It can be as hard as you want it to be.

Race description

The ÖTILLÖ Sprint Catalina swimrun course is great fun; with loops around the small community of Two Harbors. The runs are mostly flat, on easy, wide trails and the swims are mostly protected and beautiful. Yet it can be a challenge, if you want it to be. The course is very easy to follow if you have friends and family that want to come along.

An ÖTILLÖ Sprint race is the perfect swimrun race for those of you who feel that the World Series is too much or for those who want to go fast. Traditionally we have everything from very strong racers to absolute beginner Swimrunners doing the Sprint distances. Race in pairs or solo.

About ÖTILLÖ Swimrun Catalina

Catalina Island is like a dream. An island just 21 nautical miles off the California coast with endless outdoor and Swimrun possibilities. A rugged island with a 650- meter vertical drop from the highest point to the sea. Lots of bays, pebbled beaches and crystal- clear waters abundant with fish.

This Swimrun location is iconic. A stone’s throw from the 18-million people in Los Angeles you will find the landscape of Jurassic Park.

The perfect place for swimrun.

Weather in Catalina

In the end of March the island is green and the wild flowers are blooming. It is beautiful.

Like everywhere we can have wind, rain and un-seasonably cold weather, make sure you bring clothes to handle this.

To see the current weather and temperatures check out the following link. Current weather on Catalina Island.

The water in the Pacific is salty, this has an advantage as you will have more flotation, and it also has a disadvantage and that is the possibility for chafing during the race. Make sure you prepare areas that rub so you enjoy both the beginning and the end of the race.

Spectators, friends and families in Catalina

We strongly suggest that you take the time to enjoy Catalina Island and the California coast. Bring your friends and family to enjoy a long weekend or the week with you. The hotel deals is of course for them as well.

As the courses passes through Two Harbors you will be able to see the start, the middle and the end of the race from there.

NOTE: you may not assist any teams unless if it is a medical emergency. Any other assistance will result in disqualification of the team.

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!

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.
