Race overview
The Berlin Marathon is the fastest of the World Marathon Majors: a certified loop through the city center, with just 88 m of cumulative climbing across 42.2 km. The course favours runners who can hold an even, slightly-positive split — there is no terrain to "save" effort for and no signature hill to budget around. September temperatures average 9–18 °C, which is close to the metabolic optimum, so heat is rarely a dominant factor. Plan for a level pace from the gun, a moderate carbohydrate intake (60–75 g/h), and a final 7 km that turns through Potsdamer Platz before the Brandenburg Gate finish.
