Course elevation profile, 8× vertical exaggeration Elevation along the course from km 0 to km 42. The trace runs between 185 and 209 metres, a range of 24 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: Čechův most, km 0.5 to 0.7; Charles Bridge, km 2.1 to 2.6; Mánesův most, km 3.1 to 3.3; Libeňský most, km 7.2 to 7.6; Jiráskův most, km 15.3 to 15.6; Palackého most, km 16.2 to 16.4; Palackého most, km 25.4 to 25.6; most Legií, km 31.2 to 31.6; Mánesův most, km 32.5 to 32.7; Libeňský most, km 36.7 to 37.1. 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 42.2LandmarkOut and back through the same places: the Rudolfinum, the National Theatre and KarlínThree landmarks come twice, and Old Town Square three times, at 0, 12.7 and 42.2 km.

The organiser’s 2026 course overview lists the points of interest in running order, and the list repeats itself. The Rudolfinum, home of the Czech Philharmonic, is passed at 3.8 km and again at 32.5 km. The National Theatre comes at 14.5 km and again at 31.8 km. David Černý’s Lilith sculpture in Karlín is at 9.3 km and at 38.7 km.

The race starts on Old Town Square, comes back through it at 12.7 km, runs on through Celetná Street, past the Powder Tower and down Wenceslas Square, and finishes on the square where it began. Charles Bridge is at 2.8 km, Prague Castle is in view at 1.8 km and Vyšehrad is at 21.3 km. The 2027 map had not been published when this was written; the course described here is the 2026 one.

Sourced

km 9 to 14GradientThe only real rise comes between km 9 and km 14Karlín to Wenceslas Square: 23.8 m up in 4.6 km, then the road rolls near 190 m to the end.

Prague lies at about 190 to 200 m above sea level and the course stays within 24 m of one height from start to finish. The organiser puts Karlín and the Lilith sculpture at 9.3 km, where the course reaches its low point at 185.2 m. It then climbs to 209.0 m at 13.8 km, just past the organiser’s Wenceslas Square mark at 13.6 km. That is the only climb of any length: 23.8 m in about 4.6 km.

The rest is flat running. The road settles back near 190 m by the second half, and the last climb is the final 3.4 km from the dip at 38.8 km (185.2 m) back up to Old Town Square at 200.9 m.
