Splitsmith

Hamburg, April

Haspa Marathon Hamburg Pacing Plan

Starts near the Congress Centre and runs down the Reeperbahn before reaching the harbor at Landungsbrücken, with the Elbphilharmonie and the brick warehouses of the Speicherstadt in view, then follows the eastern shore of the Außenalster lake through Stadtpark. Wide, smooth roads with very few sharp turns and minimal elevation change make it a fast, PB-friendly course.

KM 0-5You open at 5:19/km, then the course dips and you'll see 5:04 at km2 — resist chasing that number. By km3 the grade ticks up to 1.4% and you hit a headwind that holds through km5, so pace naturally eases to 5:34-5:42/km here. Historical averages for this date sit around 7.9°C with 13 kph wind, so expect that headwind resistance early and don't force the pace to compensate.

KM 6-14This stretch is a genuine gift: grade drops to -0.9% to -1.4% through km6, 10 and 11, and a tailwind sets in from km7 onward, letting pace fall to 4:49-4:53/km at km10-11 without extra effort. You cross 10K at 52:36 — that's well under goal pace, which is fine here, but don't mistake this downhill tailwind push for your new normal. Let it happen, then settle back toward 5:13-5:17/km as the grade flattens into km12-14.

KM 15-21Grade is essentially flat now and wind alternates between headwind and tailwind km-to-km, so your splits should hold tight in the 5:11-5:16/km band — this is goal-pace running, nothing more. You reach the half in roughly 1:49:34, just ahead of even 3:45 pace thanks to the earlier tailwind kilometers. Bank nothing extra here; the surplus from km6-11 is your buffer, not fuel to spend now.
