Course & elevation

Des Moines is gently rolling rather than flat, touring the heart of the city past the gold-domed Iowa State Capitol, the Drake University campus and the loop around Gray’s Lake. There’s no single big climb, but a steady accumulation of moderate ups and downs gives the course more character than a pancake-flat PR route. It’s a well-organized, scenic course that runs best when paced by effort over the rollers.

Transcribed from the USATF certificate for Des Moines Marathon (IA25004MF), measured 4 and 25 August and 1 September 2024, 24 August 2025. Where the certificate is silent, so are we.

Key moments

  • Mile 1–4Out past the gold-domed Iowa State Capitol, rolling from the start; hold a conservative effort.
  • Mile 8–12Through the Drake University campus and surrounding neighborhoods, with steady ups and downs.
  • Mile 16–20The scenic loop around Gray’s Lake, a chance to settle your rhythm on calmer terrain.
  • Mile 24–26.2Rolling closing miles back toward downtown where the cumulative climb is felt.

Pacing strategy

Run the rollers by effort rather than chasing even splits, since the moderate ups and downs add up over 26 miles. Stay disciplined through the early hills, use the flatter Gray’s Lake stretch to recover your rhythm, and keep a little in reserve for the rolling return to downtown.

Pacing by goal time

Checkpoint splits for four common goals at Des Moines Marathon. These are effort-even rather than pace-even: the paces shift with the course profile, so climbs are slower and descents faster by the amount the grade actually costs. For any other goal time, use the planner below.

Splits assume even effort and are adjusted for this course's climbs and descents, which cost more than they give back. A model, not a promise: wind and heat move real splits around. See how the pacing model works.

Plan your mile splits

Turn your goal time into a mile-by-mile plan for Des Moines Marathon, built from this course's elevation. The even pace approach comes pre-selected, and grade-adjusted pacing evens out your effort across the climbs and descents.

Fueling & hydration

Aid stations roughly every 1.5–2 miles with water and sports drink. Because the rollers raise the workload slightly, fuel before the climbing sections rather than during, and keep gels on a steady schedule throughout.

Weather

Mid-October Des Moines is typically crisp fall racing weather. Starts land in the upper 30s to mid-40s and warm into the 50s or low-60s, usually dry, with the occasional wind across the open Iowa landscape.

Dates derived from the race's published pattern (3rd Sunday in October), observations at Des Moines, IA (start). Source: Open-Meteo historical reanalysis (ERA5), 7-11am local at the start line. Reanalysis is modelled from station observations, so treat it as a close record rather than an official one. See how race-morning weather is built.

Is Des Moines Marathon a good Boston qualifier?

Yes. The course actually finishes 35 ft higher than it starts, so no downhill adjustment applies, and nobody can accuse the time of being gravity-assisted.

This drop is our estimate rather than a figure from the course's certificate. If it sits near a threshold, confirm with the organizer.

Compare every course, how the downhill bands work, or work out your own target.
