How to use pace targets

  • Easy runs: conversational effort, often around Zone 2.
  • Tempo runs: controlled discomfort, not all-out racing.
  • Race pace: practice in specific blocks after a base phase.
  • Long runs: usually slower than goal pace unless prescribed.

Yes. Enter 26.2 miles and a goal time to calculate pace and split targets.

Should beginners train at goal race pace?
