Splitsmith

Warsaw, April

Warsaw Marathon Pacing Plan

Runs along the Vistula river and through the Praga and Mokotów districts on a mostly flat course, crossing back over the river twice. This is the exact GPX the founder ran his 3:02 debut on, and the plan the landing page's 'why I built this' story refers to.

KM 1-4The opening stretch drops gently (-0.3% to -1.3% grade) and you've got a tailwind pushing you along, so the watch will show 4:53-5:08/km — 6-8% faster than your overall goal pace. Let it happen, but don't chase it: this is gravity and wind doing the work, not fitness, and the course flattens out by km 5. Bank nothing extra here; just let the free speed carry you without forcing the effort.

KM 5-17The grade goes flat to slightly rolling and the tailwind fades into a headwind from km 7 onward. Settle into 5:12-5:20/km and treat this as the control zone — you cross 10K at 51:27 and 15K at 1:17:42, both almost exactly on your 3:45 schedule. This is the longest uninterrupted stretch of the race, so use it to lock in rhythm and fueling before the terrain turns against you.

KM 18-22Grade ticks up (0.4-0.9%) right as the headwind stiffens, and the data shows it: pace slips to 5:22-5:28/km, 1.5-3.7% slower than average. You cross the half-marathon mark around km 21 at roughly 1:49:41 — a few minutes off pure even-split pace is expected here and not a sign you're fading, it's the terrain plus wind combining against you. Hold effort, not pace, through this stretch.
