Cascais

Cascais and Sintra combine Portugal’s stunning Atlantic scenery with serious triathlon training appeal. Athletes can train on parts of the IRONMAN 70.3 Cascais course, swim in open-water bays or dedicated pools (including a 100m saltwater pool at Arribas Sintra), and cycle on well-maintained coastal and inland roads. The region offers mild year-round weather, varied elevation profiles, and a selection of high-performance hotels making it a premium destination for both race prep and training camps.
