Helsinki City Marathon pacing strategy

Wikipedia says the course is at sea level with a highest point of 32 m, so pacing can be even. Because there are two almost identical laps, you can use lap one to learn the route and lap two to push. Do not go out too fast.

Pacing by course section
Section	Terrain	Advice
km 0–10	Flat streets and parks near the sea	Run at or slightly slower than goal pace.
km 10–21	Seaside and park roads, first lap	Keep a steady rhythm and note any short rises.
km 21–35	Second lap on the same route	Stay on pace; you now know the course.
km 35–42.2	Final part of the second lap, finish in the stadium	Use remaining energy in the last 3 km.

Fueling notes

The organiser lists 11 refreshment stations at regular intervals, all with water and sports drink (2023 route page). Plan gels between stations so you can wash them down.
