Intro: Here’s what you need to know about “20 Kilometers (1 Mile Above Sea Level)” by Seth James DeMoor. It’s a worthwhile watch, and we’ve extracted the essential takeaways so you can run this workout today. Head to the full video for the complete breakdown.

Key Points:

• Pacing by feel: Do a quick check of your watch in the opening 1–1.5 km of a threshold run, then cover it up (or tape over it) to force yourself to run on perception alone. This develops trust in your body’s signals and cuts down your dependence on the device.
• The “art of the pivot”: Stay ready to modify the session (or push it to a different day) if conditions shift—ice, wind, heat, or terrain. Rolling with the punches keeps you training and safeguards your recovery.
• Consistency over volume: “Aerobic bank deposits”—easy runs build your aerobic foundation and make it possible to add more miles week to week without breaking down. Small, steady gains beat sporadic hard efforts.
• Watch‑glance rule: On long threshold efforts, check the watch a mere 2–3 times in the opening 1500 m, then switch to effort-based running. For a 13‑mile run, keep it to ~10 peeks total (roughly one every 1.5–2 miles).
• Threshold workout: 20 km at threshold pace (≈5:21 min/km, about 12.4 mi). Splits (minutes:seconds) tracked roughly: 5:16, 5:17, 5:16, 5:14, 5:17, 5:21, 5:23, 5:24, 5:28, 5:24, 5:28, 5:25, 5:24. Reported average pace was 5:21 min/km (≈8:34 min/mile). Heart‑rate and power metrics were also tracked.

Workout Example:

20‑km Threshold Run (≈12.4 mi / 20 km)
- Warm‑up: 10‑15 min easy jog + dynamic leg work.
- Main set: 20 km at steady threshold pace (~5:21 min/km). 
  • Goal: stay in the aerobic zone, feel steady effort.
  • Glance at watch only 2‑3 times in the first 1.5 km, then rely on feel.
- Cool‑down: 10‑15 min easy jog + stretch.

Adjust the pace target to match your threshold—pull from a recent race or a recent 5‑k effort to set a baseline. What matters most is staying relaxed, holding a stable effort, and practicing the “cover the watch” habit.

Closing Note: Take this 20 km threshold run out for a spin, dial in the paces to fit your current fitness, and log it in the Pacing app to track your progress. You’ve got this—run smooth and keep stacking those aerobic “bank deposits”! 🚀
