Intro: Here’s a breakdown of THIS Workout Will Help You Get A Marathon PB from The Running Channel. Worth watching in full for the nuances. The essential takeaways are below so you can run it today.

Key points:

  • Chris Thompson’s “Mammoth Marathon” workout is the template here. It works by depleting glycogen stores so your body learns to 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, followed by 45 to 60 minutes at marathon pace.
  • You run the whole workout unfed. The point is to push hard without relying on external fuel.
  • It’s demanding but adjustable. You can shorten the repeats, extend recovery, or dial back the speed if you’re still building your distance base.

Workout example (actionable):

  1. Warm-up. Start with 5 to 10 minutes of easy running.
  2. Intervals. Run 8 × 2 min at your current 5K race pace (about 25 min of work overall). Between each 2-min push, jog or walk for roughly 80 sec to keep the legs loose without fully recovering.
  3. Marathon-pace segment. Hold 45 minutes (or stretch to 60 if you’re ready) at your marathon goal pace, usually around 9:30 to 10:30 min per mile.
  4. Cool-down. Finish with 5 to 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 this workout and adjust the paces to match your current fitness. Your body will adapt to running fast when glycogen is depleted, and you’ll likely feel that strength kick in during the second half of your race. The intervals and marathon-pace portion are both easy to set up in the Pacing app for your specific targets. Get out there and run.
