The Thingvallasund swim event

The wind velocity must be less than 5 m/sec. (9.7 kts) for the Thingvallasund swim event to be held.

Participants must show up at the tip of Mjóanes, which is the starting point of the swim. Teammates of the swimmers must remain at the finish line and will not be allowed to ride in the observation boats. Boat traffic is discouraged in the proximity of the swimmers during the swim.

Location safety and supervision will be provided by the Icelandic Association for Search And Rescue (ICE-SAR) and will be represented by the local Search and Rescue Team in the village of Eyrarbakki.

Boats will be situated near the shore due to the hazard of slippery rocks on the bottom at the starting point of the swim.

Participants must be on dry land before starting their swim. A horn will sound the start of the swim and an observer will start timing the participants. The swim is only considered finished when a participant is completely out of the water on dry land. Only then will the timing of the swim be stopped.

A light beacon will be situated at the finish line to assist participants in orienting themselves during the swim. (In cooperation with the local SAR team)

Lifeboats will follow the participants down-current from them from start to finish.

Participants are not allowed to come into contact with the lifeboats at any time during the swim. If a participant is not able to continue with the swim, he or she shall roll on to their back and raise an arm and wait for help to arrive.

Participants may receive nourishment during the swim from the SAR team. Nourishment will be placed in front of the participants who will, after receiving nourisment, throw the container in the direction of the SAR boat. It is strongly recommended that participants be well nourished before the swim and also especially just prior to commencing the swim.

When the timing of the swim has been stopped, participants can get all the assistance they require from their teammates. It is recommended to make sure the teammates are ready with the participant’s’ gear for drying and getting dressed. Remembering to bring a hot drink is highly recommended.
