The profile of the organiser’s 2026 course file shows one rise worth the name. From about 12.6 m at km 10.3 the road climbs to about 51.5 m at km 17.8, then falls to about 4.8 m at km 25.4. The ground from there to km 40 stays between about 2.7 m and 8.3 m, so the stretch before the finish runs close to sea level.
No 2027 course is published yet, so this is the 2026 course.
Measured
The organiser puts the start and finish on Avenida 18 de Julio opposite the forecourt of the Intendencia de Montevideo. The 2026 course returns there from the low ground: it is at about 2.7 m at km 38.8, about 7.4 m at km 40, and about 39.5 m at the finish, with most of the 37 m gained in the last 2 km.
The course is the 2026 file; no 2027 course is published yet.
