Rotterdam Marathon Fueling Plan & Pace Chart

Rotterdam Fueling Strategy

Rotterdam is where European marathon records go to be broken. The course is almost perfectly flat, with only the Erasmus Bridge adding any meaningful elevation change. Three world records and multiple European records have been set here. If you're racing Rotterdam, you're likely targeting an ambitious time, and your fueling plan should match that ambition.

On a course this flat, the rules of fueling change in your favor. Steady effort means steady blood flow to your digestive system. No hills to spike your heart rate and divert blood away from your gut. No descents to jostle your stomach. Rotterdam is the kind of course where you can push your carb intake to the upper end of your trained range with minimal GI risk.

The race starts on the Coolsingel, Rotterdam's main boulevard, and heads south toward the Erasmus Bridge. The first mile is flat and fast, with huge crowds lining the wide road. Take your first gel by mile 2, before you reach the bridge. The Erasmus Bridge is the only "climb" on the entire course, rising 17 meters (about 56 feet) over its span. It's gentle enough that most runners barely notice it, but your heart rate will tick up slightly on the incline. Having a gel already absorbing before the bridge is smart timing.

Miles 3-5 bring you off the bridge and into South Rotterdam. The terrain is dead flat. Dutch topography means this course sits essentially at sea level with almost zero natural elevation change. The roads are wide, smooth, and purpose-built for fast running. Settle into your fueling rhythm here. One gel every 20-25 minutes. If you've trained your gut for high carb intake, Rotterdam is the course to deploy it. Target 80-100g of carbs per hour. The flat terrain supports this level of intake with far less risk than a hilly course.

Miles 6-12 wind through the residential neighborhoods south of the Maas River. The road surface is excellent and the terrain is featureless: no hills, no bridges, no cambered sections. Your pace should be metronomic and your fueling should match. Take gels at mile 6, mile 8-9, and mile 11. The consistency of effort on this course means your gut is operating at peak efficiency. Don't waste that advantage by spacing your gels too far apart.

Here is what makes Rotterdam different from other flat courses like Berlin or Chicago: wind. The Netherlands is notoriously windy, and April conditions can bring sustained 15-20 mph winds off the North Sea. The course layout means you'll face headwinds on some sections and tailwinds on others. Headwind sections increase your energy expenditure by 5-10% without a corresponding increase in perceived effort. On windy days, add 5-10g of carbs per hour to your baseline plan. You're burning more fuel even though your pace may not reflect it.

Miles 13-18 loop through Kralingseveer and along the Kralingse Plas (a lake on the east side of the city). The terrain remains flat. This is the middle third of the race, where the work of the first half either sustains you or starts to fade. Keep hitting your gel schedule: mile 14, mile 16. If you feel strong and your stomach is happy, this is the time to be aggressive. An extra gel in the middle miles costs nothing on a flat course and can make the difference between a strong and a fading final 10K.

Miles 19-22 bring you back toward central Rotterdam through the Kralingen neighborhood. The field has spread out significantly by now, and you may find yourself running in smaller groups or alone. Without the energy of a packed field, some runners let their fueling discipline slip. Don't. Take a gel at mile 19 and another at mile 21. These late-middle gels are the most important ones on a flat, fast course. They're the fuel that powers your final 5K.

A Rotterdam-specific fueling consideration: the on-course nutrition is European standard. Water and sports drink (typically a local brand, not Gatorade) are available at aid stations every 5 kilometers (roughly every 3 miles). The stations also offer bananas and sometimes energy bars. The sports drink may taste different from what you trained with. If you're chasing a specific time, carry your own gels and your own drink mix in a small flask. Don't leave your PR fuel to chance on an unfamiliar sports drink.

Miles 23-25 head back toward the city center. You're in the final 5K, and the crowds build as you approach the Coolsingel. If you've been hitting 80-100g of carbs per hour on this flat course, your glycogen reserves should still have something left. Take your final gel at mile 23. It won't fully absorb before the finish, but the glucose hitting your bloodstream over the final 20 minutes gives you a measurable boost for the closing miles.

The final mile on the Coolsingel is one of the great finishes in European road racing. The boulevard is wide, the crowd is deep, and the finish line appears in the distance. This is where all your disciplined, aggressive fueling on the flat course comes together. Runners who backed off their carb intake because the course felt easy at mile 8 will be fading. Runners who trusted the plan and fueled at the upper end of their range will still have gears left.

The bottom line on Rotterdam: this is a course where you should be more aggressive with your fueling than at almost any other marathon. The flat terrain eliminates the GI risks that force conservative fueling on hilly courses. The cool April weather keeps your core temperature low and your gut functional. The wide, smooth roads let you eat without dodging potholes or navigating tight turns. If you've trained your gut for 80-100g per hour, Rotterdam is where you push that limit. If you've only trained for 60-70g, consider increasing to 75-85g. The course will support it. Take advantage.
