Rotterdam, Netherlands
NN Marathon Rotterdam 2027 Pacing Plan
Starts at the foot of the Erasmus Bridge, which the course crosses twice (roughly km 3 and km 27), and loops out to Kralingen Lake in the city's east before returning along the Maas to finish on the Coolsingel. One of the fastest-rated courses in the world (average gradient close to 0.0%) with the two Erasmus Bridge crossings and two short wooden-bridge sections the only real rises on the route.

KM 0-5: You're on flat ground with a tailwind pushing you along, and it will feel deceptively easy to run 5:00/km or faster. Hold 5:11-5:18/km instead. This tailwind is a loan, not a gift: you pay it back later on the return legs, so don't spend it now.
KM 6-14: The wind swings to a headwind here and stays that way through km 14. Terrain is still flat, so the pace target barely moves, 5:12 to 5:22/km, but the effort to hold it climbs. Lean into the wind, shorten your stride slightly, and resist the urge to fight it with a faster pace; you cross 20K around 1:45:31, right on schedule.
KM 15-25: Tailwind returns for most of this stretch and the terrain stays essentially flat, so this is where the model has you running your fastest kilometers of the day, 5:13-5:19/km. You cross halfway around 1:53:00 pace-equivalent and hit 25K at roughly 2:11:56. Bank nothing extra here beyond what the table gives you: this is goal pace working with you, not a signal to push.
Frequently asked questions
Why is Rotterdam Marathon considered one of the fastest courses in the world?
The course has only 36 m of total elevation gain over 42.3 km, giving it an average gradient close to 0.0%. Aside from the two Erasmus Bridge crossings at roughly km 3 and km 27, and two short wooden-bridge sections, the route is essentially flat, removing the pacing disruptions that hilly courses cause.
How should I pace the two Erasmus Bridge crossings at km 3 and km 27?
Since the bridge is crossed twice, at km 3 while still fresh and at km 27 when fatigue is setting in, the second crossing will feel harder even though the gradient is the same. Treat both as brief efforts rather than sustained climbs, and avoid surging on the km 3 crossing since it's early in the race with 39 km still to run.
Is a negative split realistic on the Rotterdam Marathon course?
Given the near-flat profile (36 m gain, 33 m loss) and minimal elevation-driven pacing swings, a negative split is realistic on this course from a terrain standpoint. The main variable working against it is the second Erasmus Bridge crossing at km 27, which lands right as the race gets physically harder, so even splitting or a slight negative split are both viable strategies here.
What weather should I expect on race day in Rotterdam, and how does it affect pacing?
Typical race-day conditions are around 8.5°C with wind near 13.2 km/h, cool temperatures that favor consistent pacing without significant heat-related slowdown. The wind is the more relevant factor on this flat, exposed course, particularly along the Maas riverside sections and the two bridge crossings, so runners should account for possible headwind segments when setting target splits.
Where are the only real rises on the Rotterdam Marathon course?
The only notable elevation changes are the two Erasmus Bridge crossings (km 3 and km 27) and two short wooden-bridge sections encountered during the loop out to Kralingen Lake. Everything else, including the finish stretch along the Coolsingel, is effectively flat, so pacing plans need only account for these four brief rises rather than sustained climbs.
