Intro

This is a quick summary of (THIS) does not LIE in Running from Seth James DeMoor. It’s a great watch — we’re breaking it down so you can try the workout today. Be sure to check out the full video for all the details.

Key Points

Fitness doesn’t lie – when you’re consistently putting in the work, your body tells you when you’re truly fit.
Back‑to‑back hard days (once or twice a month) teach your body to run when you’re already tired, a key for marathon/ultra‑marathon races.
Consistency & balance – regular runs, effective interval work, and proper recovery are essential. If you want to dive deeper into the science behind this, you can learn more about Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them.
Progressive run‑walk intervals help you build up to a straight 5k/3-mile run. This is a fantastic way to build endurance, and if your goal is a faster 5k, these kinds of workouts are foundational. You can find more targeted strategies in our guide to Mastering 5K Speed: Proven Interval Strategies to Cut Minutes off Your Time.

Workout Example

Weekly Structure (example from the vlog):

One day off – rest.
Two days of walking – active recovery.
Two days of intervals – 12 min run / 3 min walk, repeat twice, finish with a walk.
Two days of straight runs – 25 min straight run.
Progressive runs (optional):
- 10‑minute run + walk
- 15‑minute run + walk
- 25‑minute run (no walk)
- 35‑minute run (no walk)

This progression moves you from short run-walk intervals toward longer, uninterrupted runs. As you build the endurance needed for longer distances, you can start applying these principles to more ambitious goals. For example, once you’re comfortable running for 30-40 minutes straight, you’ll have a great foundation for Mastering the 10K: Proven Training Plans, Pace Strategies, and How a Smart App Can Elevate Your Performance.

Closing Note

Give this progressive run‑walk plan a try and tweak the times to match your own paces in the Pacing app. Consistency is the key—keep putting in the work, stay balanced, and watch your fitness level rise! 🌟
