The trace runs between 5 and 56 metres, a range of 51 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.

km 0 to 36GradientFlat from the ocean, one drop near the endA slow climb from 5 m to 56 m at km 31.7, then a fall of 49 m over three kilometres.

The 2026 course is a long, gentle rise from the waterfront rather than a set of hills: about 25 m by km 10, 44 m by the half-way point and 55.7 m at km 31.7. The next 3 km drop about 49 m, to about 6 m at km 34.7, and the finish is back near sea level at about 5 m.

The organiser describes the course as “flat and fast” and gives it “only 200 metres of elevation gain over 42 km”; the rise and fall above come to less.

km 0 to 0.5LandmarkStart and finish beside the Hassan II MosqueStart and finish are by the Hassan II Mosque; the 2026 waves go at 7:00 and 7:05.

For the 2026 race the organiser puts the start and finish together “near the Hassan II Mosque (Bd Sidi Med Ben Abdellah, opposite Rue Regraga)”, reached by tram T1 (stop “Hassan II Mosque”), bus, or on foot. The marathon goes at 7:00 for the elite runners and wave 1 (under 3 hours), and at 7:05 for wave 2 (over 3 hours). The organiser asks runners to arrive at least 45 minutes early.

km 10.5 to 31.5CrowdA course shared with a half and a four-person relayThe half and the relay share the course; relay handovers are at km 10.5, 21 and 31.5.

The organiser offers “three formats, one course through Casablanca” in 2026: the marathon, the half marathon and a relay of four runners over segments of about 10.5 km. The marathon has 9 aid stations from km 5 to km 40, and the half has 4, from km 5 to km 20. Marathon pacers are set for 3:00, 3:15, 3:30, 3:45, 4:00 and 4:15.

The relay starts at 7:15, fifteen minutes after the marathon. It changes over at signposted zones at 10.5, 21 and 31.5 km, and the last relay runner crosses the official finish line.
