Amsterdam, Netherlands
TCS Amsterdam Marathon 2026 Pacing Plan
Starts and finishes inside the 1928 Olympic Stadium, and spends the first half along the Amstel river out toward Ouderkerk before looping back through the historic canal ring. Flat by Dutch-course tradition, with the finish's lap around the Olympic Stadium track (the same stadium that hosted the 1928 Games marathon) as its signature moment.

KM 0-5: You're fresh and the field is fast around you, but hold 5:08-5:16/km through here: this is the quickest stretch of the whole course by the numbers, with a tailwind pushing km 1-3. Don't chase runners going out harder; you cross 5K at 26:01, right on schedule. Banking time here doesn't exist in this plan. The fade later is already built in, so going faster now only steepens it.
KM 6-16: A sustained headwind sits on you from km 5 through km 20, and this stretch also carries the day's only real undulation: 5:20-5:25/km around km 6-7 and again 5:21-5:23/km at km 13 and 15. Treat the headwind as an effort tax: the pace numbers are terrain-only, so if 5:20 feels harder than it should, that's the wind, not you fading. You hit 10K at 52:13 and 15K at 1:18:30. Both should feel controlled, not laboring.
KM 16-21: Km 16 is your fastest of the race at 5:00/km on a downhill stretch, let it come, don't force more than that. The headwind persists to km 20, then eases into a tailwind right as you approach halfway. You reach the half in roughly 1:52-1:53 pace terms, still within a few seconds of your opening kilometers: this is the last point where the race feels even.
Frequently asked questions
Is the Amsterdam Marathon course flat enough for a PR attempt?
Yes, with only 43 m of elevation gain and 44 m of loss over 42.8 km, this is a genuinely flat Dutch course. There are no significant climbs to disrupt pacing, so runners can focus on even effort rather than managing hills.
What pacing strategy works best on the Amstel river out-and-back section?
The first half follows the Amstel river out toward Ouderkerk, a flat, exposed stretch where wind (typically around 13.3 km/h on race day) is the main variable rather than terrain. An even-split approach suits this section well since there's no elevation to justify holding back or pushing early.
How should I handle the finish inside the Olympic Stadium?
The race finishes with a lap around the historic 1928 Olympic Stadium track, the same venue that hosted the 1928 Games marathon. Since the course is flat throughout, runners have the option to save a slight surge for this final signature lap rather than needing it to offset late-race climbs.
Does wind affect pacing more than elevation on this course?
Given the minimal elevation change (43 m gain, 44 m loss), wind is the more relevant variable on race day, with typical conditions around 13.3 km/h. The Amstel river stretch in the first half is likely the most exposed section, so factoring wind direction into your pacing plan matters more than adjusting for hills.
Is a negative split realistic on the Amsterdam Marathon course?
Because the course is flat by Dutch tradition with negligible net elevation change, a negative split is achievable without terrain working against you in the second half. The second half winds through the canal ring before returning to the Olympic Stadium, so effort management rather than elevation is the deciding factor.
