Splitsmith

Stockholm, May

ASICS Stockholm Marathon Pacing Plan

Starts near the Olympic Stadium, spends km 14-21 looping Djurgården island — flat at first, then a steady climb toward Manillahuset — crosses the long Västerbron bridge for panoramic city views, and finishes back inside the 1912 Olympic Stadium. The most demanding section is Djurgården's rise and the roughly 600m sloped stretch on Narvavägen; total gain is around 150m of mostly gentle rather than steep terrain.

Sample strategy — 3:45:00 goal

A real, AI-generated excerpt of what Splitsmith produces for this exact course — not a hand-written example. Upload your own goal and recent results to get the full plan.

KM 1-5You open at 5:20/km through the crowd, a touch slower than the 5:20 average pace you need for 3:45 — that's fine, let the field thin out. Kilometers 2-4 drop net downhill (grade -0.6% to -0.1%) and pace naturally quickens to 5:01-5:10/km with a tailwind pushing you along; don't chase it harder than that. Km 5 is the steepest downhill of the whole race at -1.6%, giving you 4:46/km almost for free — bank the time here, not by forcing effort.

KM 6-11The course flattens and tilts slightly uphill (0.1% to 1.0%) from 6 to 9, and a headwind sits on you for most of this stretch, pushing pace out to 5:15-5:30/km. Hold that — it's still on schedule, you cross 10K at 51:59. Km 12 gives brief relief with a -1.1% downhill dropping you to 4:54/km; treat it as a small reset, not a signal to surge.

KM 13-21This middle stretch is mostly flat to gently rolling, paces settling in the 5:05-5:22/km band with mixed tailwind and headwind. Nothing here should feel hard — if it does, you went out too fast in the first 5K. You cross the half-marathon point around km 21 at roughly 1:48:49, dead on pace for 3:45.
