How to read your easy pace (and why it should feel too slow)
If you take one habit from why the easy weeks build your race and actually apply it, make it this: run your easy days easy. It sounds obvious, and almost everyone gets it wrong. The most common training mistake isn't skipping workouts — it's running the easy miles a little too hard, every single day, until there's no easy left at all.
What "easy" actually means
Easy pace is a conversational effort: you could hold a full sentence out loud without gasping. Physiologically it sits below your first ventilatory threshold — the zone where your body clears fatigue as fast as it builds it, so you can accumulate volume without digging a hole. That's the whole point of the 80/20 split: about 80% of your running lives here, building the aerobic base, at low injury and fatigue cost. See the research →
The "too slow" feeling is the sweet spot
Here's the catch: a genuinely easy pace usually feels too slow — almost embarrassingly so — especially early in a run when you're fresh. That feeling is exactly right. If your easy runs feel "comfortably moderate," they're probably creeping into the grey zone: too hard to recover from, too easy to count as a real workout. The grey zone is where tired legs and stalled progress come from.
Three ways to find it
- The talk test — the simplest and most reliable. Full sentences, comfortably. If you're snatching breaths between words, slow down.
- Effort, not the watch — on hills, heat, or tired legs, the same easy effort will be a slower pace. Let it be. Chasing a fixed easy pace on a hot day turns it into a workout.
- Heart rate, loosely — if you track it, easy tends to fall well below threshold. Treat it as a guardrail, not a target; the talk test already gets you there.
Save your hard for the hard days
Running easy isn't lazy — it's what makes the other 20% count. When your easy days are truly easy, you arrive at your workout fresh enough to hit it properly, and the hard session actually does its job. Run everything at a medium effort and you get the worst of both: no real recovery, no real stimulus.
