Easy miles / Zone 2

Also known as

zone 2 · easy run · conversational pace · 80/20 · easy cardio

Community talk. May contain inaccuracies. Not medical, training, or diet advice. Sharp pain, fainting, or disordered-eating concerns need a clinician.

In brief

Easy miles are runs kept at a comfortable effort, while Zone 2 is a training-zone label whose definition depends on the system being used.

The common picture
Talk test: full sentencesThe free definition on r/running.
Easy share slogan: about 80% of the weekThe notes retain this as a discussion shorthand.
Walk, easy jog, bikeWhatever they will repeat. Bike is easier to stay easy on.
Sessions: 20–60 minutes, often 2–4 times a weekSome longer-week accounts describe 2–4 total hours of easy work.
One hard day at mostThe sibling card. Not five.

Runners compare conversational effort, pace and heart-rate displays when deciding what counts as easy, especially when those indicators seem to disagree.

Good to know. If you cannot talk, it is not easy. A gadget is optional. Calling a hard 5K a base-builder.

What people say

  • The job: Build a base they can repeat.
  • 2026 r/running: “do I even need Zone 2?” is a weekly thread. The answer in the comments is usually “you need easy volume, the brand name is optional.”
  • Strength Running (Nov 2024 and after): Zone 2 needs volume; a tiny easy jog is not a program.
  • Seiler’s polarized model (lots easy, a little hard) is the coach version of the same week.
  • Attia / San Millán made Zone 2 a personality. 2026 threads ask if it is oversold. Hybrid people keep both easy and one hard day.
  • Maffetone (180 − age) still has fans as an HR cap.
  • Recreational runners race their easy days because easy feels embarrassing.
  • You don’t need a $400 strap to start. The sentence test is the tool.
  • Watch algorithms lie on heat, caffeine, and bad sleep.
  • Self already has a Zone 2 habit card. This card is the running session.
  • 12–3–30 and rucking often land in this band if they can still talk.

How people do it

  • Slow down until they can talk.
  • Save the hard day for one session, not five.
  • Hills: they walk or shuffle instead of racing.
  • Podcast pace is a synonym. If they cannot follow the sentence, they slow down.
  • Indoor bike + a show is how rainy people keep minutes.
  • They do not check Strava average pace as a score on easy days.
  • New runners: walk/run is still easy miles. See Couch to 5K.

Amounts people use

  • Share people quote: about 80% easy.
  • Time: 20–60 min a session; Attia-shaped talk is 2–4 hours/week easy.
  • Days: 2–4 easy sessions.
  • HR talk: roughly 60–70% HRmax, or Maffetone 180 − age. Individual.
  • Lactate nerd target: ~1.5–2.0 mmol — lab people only.

How people keep it

  • A loop they know is slow. Same route, no racing the segment.
  • A buddy who will actually talk.
  • Bike if the jog always turns into a tempo.
  • They hide the pace on the watch if they cannot resist.
  • Easy is the default. Hard needs a reason.

How it may feel

  • Embarrassingly slow. Then the long run stops wrecking Tuesday.
  • Ego death in public. Someone they used to pass is still chatting.
  • After a month: they finish fresher. That is the hook.
  • If they keep racing easy days: they are tired and “not built for running.”
  • Heat / bad sleep: the same pace is no longer easy. They slow more.
  • The good version: slightly bored, slightly proud they did not race.

How long

  • Most weeks they run. This is the default, not a phase.
  • Base-building blocks are almost all this.
  • Race season still keeps most miles easy.
  • A week of only hard sessions is how people get injured and take a month off.

The longer notes

  • Zone 2 the brand vs easy the job. The job is what matters.
  • Couch-to-5K is the named walk/run on-ramp.
  • Long run is just a longer easy day for most people.
  • Hard cardio / VO2 is the one expensive day.
  • Steps are not automatically Zone 2. A purposeful easy session is.

More from the community

One runner in a February 2026 Q&A reported an easy-feeling run that a device classified very differently by pace and heart rate. The resulting question was about which zone label to follow, not whether the runner had tried hard enough. A report of Zone 2 therefore needs its measuring context: heart-rate zone, pace zone and a description of effort are not the same piece of information.Source 1
