Leaving the city buzz behind means diving straight into Atlantic mode. The route kickstarts at the lively Praça do Comércio, heading downriver along the Tagus. It rolls right under the massive 25 de Abril Bridge, passing the futuristic MAAT museum and the classic sights of Belém. Once the iconic tower fades into the distance, the ocean takes full control. Cruising along flat coastal paths and smooth tarmac brings the first real scent of sea salt. The wide beach of Carcavelos offers a perfect excuse for a quick espresso break before gliding through historic Estoril. By late afternoon, the track finishes in the charming old town of Cascais. A flat, straightforward warm-up to dial in gear and pace.
