Located on the northern edge of the Canary Islands off the northwest coast of Africa is considered by many to be one of the toughest IRONMAN events in the world.
The swimming takes place at Playa Grande, Puerto del Carmen, the main tourist resort of the island. It is a two-lap course with a short running passage between the two laps.

The cycling course, well known for challenging athletes with strong island winds, takes you all around the island with over 2551 m. of climbing. Participants will enjoy amazing views and will have lots of support from the volunteers along the way. The bike circuit will be open to traffic and circulation will be controlled by the police. Please be careful at all times. Obey all police officers under all circumstances.

Consisting of 3 laps, the marathon course is run on the flat seafront of Puerto del Carmen. You will enjoy beautiful views of the ocean under the intense Lanzarote sun, while feeling the impressive support of thousands of spectators alongside the run course. The first loop of 21.10km takes you to Playa Honda and back, with the next two loops covering 10.55km each.

There are 40 qualifying slots for the IRONMAN World Championships.
