Where does it start and finish?
A scenic point-to-point along the Douro river and Atlantic coast, finishing near the waterfront with river and bridge views throughout.
Where should I stay?
Ribeira / Baixa for the historic riverside centre; Vila Nova de Gaia across the river puts the port lodges (and finish area) on your doorstep.
How do I get from the airport to the start?
OPO airport is ~30 min on Metro line E (violet) straight into the centre — the easiest airport transfer of the five.
What else is on that weekend?
Port-cellar tastings in Gaia, a Saturday shakeout across the Dom Luís I bridge, and a Douro valley trip if you add a day.
