Long run progression

A practical long-run progression guide: how to increase time safely, when to cut back, and how to use long runs to rehearse pacing and fueling.

The point of the long run

A long run is not a weekly time trial. It’s your durability builder.

Your job is to finish long runs thinking: “stable, repeatable, I could do more.”

The safe progression rules

  • Progress slowly. Most runners do best when long runs increase gradually.
  • Cut back every 3–4 weeks. You absorb training on the easy weeks.
  • Keep it easy. Most long runs should be conversational.
  • Add structure only when recovered. Tempo belongs on fresh legs.

What makes a long run “good”

  • You can train again in 24–48 hours.
  • You can keep form late.
  • You rehearse race-day habits (pacing discipline, fueling, hydration).

What makes a long run “bad”

  • It forces you to skip workouts all week.
  • It becomes a high-stress race simulation.
  • You ignore pain signals and stack fatigue.

Checklist

Do this, not that

Long-run safety checklist

  • I can keep easy effort truly easy (conversation test).
  • I have a cutback rule (every 3–4 weeks).
  • If sleep is poor, I shorten the long run by 15–25%.
  • I don’t ‘make up’ missed sessions by turning the long run hard.
  • I keep the first 20 minutes conservative — no ego pace.
  • I practice fueling early (start before I’m starving).
  • If pain changes my gait, I stop and scale down next week.
  • I plan the day after: easy, low-impact, or rest — not another hero session.

FAQs

How long should my long run be?

It depends on your race and base. Increase gradually, include cutback weeks, and avoid long runs that wreck the rest of your training.

Should I do marathon pace in long runs?

Only when you’re recovered and it’s planned. Most long runs should be easy; structured segments are a tool, not a weekly requirement.

What if I miss a long run?

Don’t cram. Return to the last long run you handled well, then progress again. Consistency beats panic make-ups.
