IRONMAN Portugal - Cascais

 Athletes racing in IRONMAN Portugal-Cascais will face a single-loop 3,8 km (2.4-mile) swim in the Bay of Cascais and exit the water at the Fortaleza at Club Naval. After transitioning onto their bikes, athletes will tackle a unique 180,2 km (112-mile) bike course that leads along the Guincho Beach road and to Sintra before athletes are treated to racing on the Formula 1 and Moto GP circuit of Estoril. Athletes end the cycling portion of the race with two shorter loops on flat roads next to the Ocean between Lisbon and Cascais. The three-loop 42,2 km (26.2-mile) run course starts in Cascais and leads back to Guincho Road. It then follows the shoreline to Cabo Raso and back to Cascais for a celebratory finish.
