A swim course with a rolling swim start. A single 3.8km loop course that leads athletes along the protected Cascais Bay, starting at Praia da Ribeira and finishing in front of the Fortress at the Clube Naval. In October, the water temperature varies between 17 and 19 degrees Celsius (62.6 and 66.2 degrees Fahrenheit).Bike course
The 180 km two-loop bike course offers breathtaking views of the Portuguese Riviera, Guincho Beach and the wonderful natural park of Sintra–Cascais, which as a result of the improvements made to the route, will allow the athletes to pedal on roads that boast rare scenic beauty. A ride in Estrada do Guincho leads to Malveira and Serra de Sintra by the Blue Lagoon, towards the Estoril Formula 1 Circuit. Athletes get to enjoy smoother roads that take them all the way to the turning point in Lisbon, passing by some of the icons of the Portuguese capital, such as the Tower of Belém, the Jerónimos Monastery, and even under the 25th of April Bridge. The athletes will also enjoy a unique feature unlike any other IRONMAN event: a lap around the Estoril Formula 1 circuit.Run course
The 3 loop HOKA run course starts in Cascais, then follows the Guincho road along the coast to Cabo Raso and returns to the heart of Cascais. A challenging course, especially on a windy day. This run course is known for its awesome spectator support, especially with the passage in Marina de Cascais, with cheers that will take you all the way to the finish line.
