The 2026 race finishes at the Queimódromo, next to Parque da Cidade do Porto. The wardrobe is there too, next to the finish line: bags are handed in and collected at the same place, and the locker position follows the last digit of the bib number. At the finish there is water, solid food and beer.
Sourced
Km 5 has water only. Km 10 and km 15 add solid food. From km 20 to km 35 each point adds a sports drink as well, and km 40 goes back to water and solid food. In 2026 the marathon started at 8:00 with a 6-hour limit, and pacers ran the marathon for 3:00, 3:15, 3:30, 3:45, 4:00, 4:15, 4:30 and 4:45.
Sourced
With the 2026 race’s 8:00 start, the last runner was due at km 5 at 8:37, km 10 at 9:25, km 15 at 10:08, km 20 at 10:51, the half marathon at 11:04, km 25 at 11:31, km 30 at 12:27, km 35 at 13:07, km 40 at 13:42 and the finish at 14:00.

Sourced
The start on the seafront by the Castelo do Queijo sits at about 10 m. The first loop heads inland round Parque da Cidade and rises steadily to the course’s high point, 33 m at km 2.4, then falls back towards the sea: 16 m at km 4, 12 m at km 5.5 by the Matosinhos roundabout.
From there the course follows the water. Matosinhos, the port of Leixões and Leça da Palmeira stay between 5 m and 15 m; the seafront south to Foz between 6 m and 13 m. Along the Douro, from km 21 to km 38, the line runs between 3 m and 23 m, with its low point, 3 m, at km 30.2 at the turn by Freixo. The last kilometres back along the sea stay between 9 m and 14 m.
Over the whole race that comes to 133 m of climbing.
Measured
