Fort of São Bruno

The course passes the fort on the shore at Caxias, about 5 km in.

Height drawn many times taller than life. Heights: GEDTM30.

Course elevation profile, 8× vertical exaggeration Elevation along the course from km 0 to km 10. The trace runs between 4 and 34 metres, a range of 30 metres, drawn at 8 times vertical exaggeration so the shape is legible. Smoothed over 1 km before this profile was derived. An unsmoothed urban surface carries the buildings and would assert a climb that is not there. The dashed stretches are bridge decks: Avenida Ivens, km 1.8 to 1.9. A bare-earth model reads the ground or the water beneath a bridge, not the deck the runner is on, so those runs are interpolated between the ground either side rather than measured, and they under-report the real climb across a span.

km 0 to 10GradientOne hill in the first 5 km, then the sea roadUp to 33.8 m at 3.2 km, down to 3.9 m by 5 km.

The 10 km runs west from Algés to Oeiras along the Avenida Marginal. Almost all the climbing comes in the first third: the road rises about 29 m between 1.6 and 3.2 km, and after 5 km the road stays below 15 m.

km 0 to 10GradientThe organiser's own climb figuresThe organiser lists 107 m up, 97 m down, 16.2% at the steepest.

The organiser also gives an average gradient of 1.7% uphill and 1.5% downhill. Its ascent counts every short rise, which is why it runs well above the 46.5 m of climbing in the course record.
