Race guide

Use the current countdown

The plan examples below were written in July 2026. Their 13-, 14-, 16- and 18-week references describe those planning dates, not the time remaining today. Use the main guide’s current race date and start-date calculator. Do not join a late plan week unless its workload matches your recent training.

The useful answer

The 2026 IMT Des Moines Marathon is on Sunday, October 18, with the marathon starting at 8:00 a.m. The organizer's current course information lists a seven-hour time limit. As of July 20, about 13 weeks remain.

Thirteen weeks is a useful race-specific runway when you already have a stable running habit. It is not enough time to safely manufacture months of missing consistency by stacking long runs and speedwork.

Choose the right 13-week lane

Your current baseTraining lane
Consistent running plus a recent comfortable long runUse a 13-week race-specific block with gradual long-run progression, one controlled quality session, and taper
Consistent short running but limited long-run durabilityUse a completion-first plan, increase time on feet conservatively, and remove aggressive pace targets
Interrupted training, current illness, or pain that changes gaitDo not cram; consider a shorter event or later marathon and seek appropriate professional guidance when symptoms persist

Weekly structure

The exact distance should come from your current load and recovery, not from a generic peak-week number.

  • One long run: build durable time on feet and practise fuel.
  • One controlled quality session: tempo, hills, or marathon-effort work—not all three.
  • Easy running: most of the week, genuinely easy.
  • Strength: two short sessions if already tolerated, reduced as the race approaches.
  • Recovery: at least one low-load day and no automatic make-up sessions.

Thirteen-week progression

PhaseWeeksFocus
Reset13–11Stabilize frequency, easy effort, long-run routine and sleep
Build10–7Gradually extend the long run and rehearse fueling
Race-specific6–4Controlled marathon-effort blocks and the same breakfast/fuel timing planned for race day
Peak to taper3–2Complete the final substantial long run, then reduce load
Race week1Familiar movement, current organizer checks, no novelty

If recovery worsens for several days, reduce the next load rather than defending the calendar. Training adapts to the person; the date does not make a missed session safe to cram.

Rehearse the 8 a.m. start

An 8:00 a.m. start makes the pre-race routine trainable:

  1. Run selected long runs at a similar time.
  2. Rehearse breakfast timing and bathroom access.
  3. Practise your first fuel before you feel depleted.
  4. Use the same shoes, socks, anti-chafe and carrying method.
  5. Check the current start location, parking, expo and course plan before race week.

The official FAQ currently lists all races starting and finishing at 212 Raccoon Street for 2026. Treat the final athlete guide as authoritative if operations change.

Seven-hour pacing check

A seven-hour limit averages roughly 9:57 per kilometre / 16:01 per mile, before allowing for aid stops or unexpected delays. This is not a recommended pace. It is a planning check: practise moving, fueling and handling short stops so the cutoff is not discovered on race morning.

Race-week checklist

  • Read the current athlete guide and FAQ.
  • Confirm the start, expo, parking and any intermediate cutoff.
  • Check the forecast and adjust effort rather than forcing a split.
  • Keep the first miles calm.
  • Use only food and gear already tested in long runs.
  • Stop and seek help for serious symptoms; a finish goal never outranks health.

Race-day strategy

  • Start conservatively and use effort when terrain, wind, or crowding changes.
  • Rehearse the same pacing cues during key sessions.
  • Rain is plausible in the climate record. Rehearse friction control and use tested footwear if the forecast is wet.

FAQs

When is this race?

IMT Des Moines Marathon is listed for October 18, 2026. This date refers to the race represented in this guide; other distances and expo activities may run on different days. Source checked 2026-10-18.

Where should I confirm the latest date and start logistics?

Use the official race website first. If an athlete guide is published, treat it as the reference for expo, bib pickup, and start procedures.

How do I register for this race?

Registration rules vary by event and year. Use the official website and registration page links above, and confirm any lottery windows, qualification rules, and transfer policies before you plan travel.

How far in advance should I start training?

Pick a plan length that matches your base and injury history (often 16–24 weeks), then train backward from race day and include a taper.

What is the best pacing strategy for this course?

Start conservatively, settle into rhythm, and protect the final 10K. Use effort cues if conditions change.

What should I focus on in the last 4–6 weeks?

Race-specific long runs, fueling practice, and dialing in pacing cues. Avoid late ‘hero’ sessions that spike injury risk.

What if I don’t know my goal pace yet?

Use the pace calculator to explore scenarios, then anchor training by effort and recovery. Your goal pace should be earned in training, not guessed on race week.

How should I plan fueling for race day?

Practice your fueling schedule in long runs and use a conservative default early (carbs, fluids, and sodium). Adjust for heat and your gut tolerance.

What if the forecast is hotter than the climate context?

Treat heat as a pacing variable. Start more conservatively, fuel and hydrate earlier, and practice one or two long runs with heat adjustments so your race-day plan isn’t improvised.

How should I handle travel stress or jet lag?

Protect sleep and keep the plan simple: arrive with a buffer, keep walking low, rehearse transport to the start, and avoid adding new workouts or new foods late.

When should I practice fueling so it actually works on race day?

Start practicing early — not in the final week. Rehearse the same gel/fluid schedule during long runs at steady effort so your gut tolerates it under load.

How many weeks until this race?

IMT Des Moines Marathon is listed for October 18, 2026. This date refers to the race represented in this guide; other distances and expo activities may run on different days. Source checked 2026-10-18.

When is the 2026 this race?

The organizer lists Sunday, October 18, 2026, with an 8:00 a.m. start for the marathon and other timed distances.

Is 13 weeks enough to train for Des Moines?

Thirteen weeks can be a useful race-specific block for someone with consistent running and long-run durability. It is not enough time to safely replace a missing base by cramming volume.

What is the Des Moines Marathon time limit?

The organizer's current course information lists a seven-hour course limit. Confirm the final 2026 athlete guide and any intermediate restrictions before race day.

How should I structure a Des Moines training week?

Use one long run, one controlled quality session, mostly easy running, strength only when it remains recoverable, and at least one low-load day. Do not stack missed sessions.
