Easy running and effort

Easy running is the low-intensity running that makes up most of an endurance runner's week, done at an effort you could hold a conversation at. Most runners get the easy days wrong in one of two directions: too hard because the pace feels slow, or anxious because the pace drifted. These questions cover what effort, pace and heart rate each tell you on an easy day.

• Are my easy runs actually easy?

  A no-lab test for whether your easy runs are easy: the talk test, what heart rate adds, why easy days drift too hard, and what to check in your own runs.

• Should I run easy when I feel great?

  Why an easy day stays easy when you feel great, what feeling fresh does and doesn't measure, and what to check before running a little faster.

• Why does easy pace feel harder some weeks?

  Why the same easy effort gives a slower pace some weeks: heat, sleep, dehydration and training load, and how to tell a bad week from a real slowdown.

• Why do legs feel dead after easy runs?

  What delayed onset muscle soreness is, why a slow pace doesn't decide how sore your legs get, and the signs that point past ordinary soreness.

• Why does the same pace feel harder in the heat?

  Why a familiar pace feels harder in the heat: where your blood goes, what sweat costs, how heat acclimation helps, and how to compare hot and cool runs.

• Does cadence actually matter for a recreational runner?

  What cadence changes in your stride, why the popular 170 to 180 range is not a rule for you, and what to check in your own running data instead.

• Should my long runs be at race pace?

  What a long run builds, why running it at goal race pace costs more than it gives, and when a race-pace finish belongs in your long run.
