Intro: Here’s a breakdown of THIS Workout Will Help You Get A Marathon PB from The Running Channel — definitely worth watching in full to see all the nuances. We’ve distilled the essential takeaways below so you can run it today.

Key Points:

  • Chris Thompson’s “Mammoth Marathon” workout provides the template for this session, which works by deliberately depleting glycogen stores so your body can hold marathon pace even when energy runs low.
  • The structure is straightforward: a short warm-up, then 8 × 2-minute repeats at 5K race pace, with 80-second jog/walk breaks between each, followed by 45–60 minutes at marathon pace.
  • You’ll run the entire workout unfed — the objective is to push hard without relying on external fuel.
  • It’s demanding, but adjustable: you can shorten the repeats, extend recovery periods, or dial back the speed if you’re still building your distance running foundation.

Workout Example (actionable):

  1. Warm‑up – Start with 5–10 minutes of easy running.
  2. Intervals – Run 8 × 2 min at your current 5K race pace (≈ 25 min of work overall). Between each 2-min push, jog or walk for roughly 80 sec to let your legs stay loose without fully recovering.
  3. Marathon‑pace segment – Hold 45 minutes (or stretch to 60 if you’re ready) at the speed you’re targeting for your marathon goal — usually around 9:30–10:30 min per mile.
  4. Cool‑down – Finish with 5–10 minutes of easy jogging. Tip: If the full 45 minutes feels out of reach, drop to 30 and build from there over the coming weeks. The Pacing app makes it simple to lock in your 5K and marathon paces.

Closing Note: Try running this workout and adjust the paces to match where you’re at fitness-wise. Your body will adapt to the demands of running fast when glycogen is depleted, and you’ll likely feel that strength kick in during the latter half of your race. The intervals and marathon-pace portion are both easy to customize in the Pacing app for your specific targets. Get out there and run.
