The long run

Also known as

long run · weekend long run · time on feet · sunday long run

Community talk may be wrong. Not medical, training, or diet advice. Sharp pain, fainting, or disordered-eating concerns need a clinician.

In brief

A long run is the longest or one of the longest running sessions in a person’s current training week.

The common picture
One longer easy dayUsually the weekend. The other days stay shorter.
Still conversationalIf they cannot talk by mile 4, it was not a long run. It was a race.
~20–30% of weekly mileage talkA common forum picture, not a law.
Walk breaks allowedEspecially early, heat, or hills.
Food after, easy next dayThe workout includes the sandwich.
Beginner long-run reports: 40–70 minutesThe examples keep it easy and often increase by 5–15 minutes at a time.
Planned walk-break example: 9 minutes running / 1 walkingSome take breaks as needed; others use a repeating split.

Runners discuss duration, distance, pace, route and how the session fits with the rest of the week; long is relative to the runner’s present routine.

Good to know. Turning it into a tempo. Jumping mileage 20%+ a week. Stacking it the day after intervals.

What people say

  • The job: Teach the body and the brain that they can keep going.
  • r/running treats the long run as sacred and then tells people they went too fast.
  • Time-on-feet is the phrase when pace is a trap.
  • New runners: 40 minutes can be a long run. It does not have to be 12 miles.
  • Marathon people make this a 16–20 miler. That is a later, louder card. Same rule: easy.
  • The bonk is the diary — they went long, under-ate, and met the sidewalk.
  • Social long runs (run club) are how people keep it. They also go too fast in a pack.
  • Treadmill long runs are legal and boring. Shows help.
  • Hyrox people need a long-ish easy run too, not only stations.
  • After C25K: one of the three days just grows. That is a long run.
  • Back-to-back long days are an advanced ultra trick, not week four.

How people do it

  • Pick one day with nothing hard after it.
  • Start slower than they think. First miles are a warmup.
  • Carry water / a snack once they are out over an hour.
  • Hills and heat: they walk. The long run still counts.
  • They do not check the 5K split.
  • Next day is easy or off. Legs will vote.
  • If life shrinks: a medium-long still beats a heroic 14 that wrecks ten days.

Amounts people use

  • Beginner long: 40–70 minutes easy.
  • Share of the week people quote: about 20–30% of weekly mileage.
  • Add: 5–15 minutes a week, not a sudden doubling.
  • Walk breaks: as needed. Some use 9 run / 1 walk on purpose.
  • Fuel talk after ~60–75 min: a gel or a real snack. Individual.

How people keep it

  • A weekend morning that is already protected.
  • A loop they can cut short if it goes wrong.
  • A friend slightly slower than their ego.
  • A recovery meal they like.
  • They write the time, not the pace.

How it may feel

  • Miles 1–2: stiff, doubtful.
  • The middle: this is why people become runners.
  • The last 15 minutes: honest. Character, or a snack, or both.
  • Afternoon: sleepy and proud. Or wrecked if they raced it.
  • Tuesday after a too-fast long: the week is already lost.
  • A good cycle: the old long run is now a medium day.

How long

  • Most weeks of a running year.
  • They taper it before a race.
  • In a cut or a hot month: they hold time and slow down.
  • After injury: they rebuild duration before pace.

The longer notes

  • It is an easy day that is long. Not a third workout quality.
  • Tempo and VO2 do not belong inside the long run for most hobby people.
  • Rucking a long day is a different tax. See Rucking.
  • C25K graduates grow one day. They do not jump to 10 miles.
  • Self run-club is the social wrapper.

More from the community

In a February 2026 Q&A, a runner with limited time asked about a half-marathon long run that occupied a large share of weekly mileage. Replies differed over whether a percentage rule was useful at that weekly volume and how concentrated the training had become. The question was not answered by distance alone. Available training days, the rest of the week and the intended event explain why two runners may use the same words while describing different demands.Source 1

Good to know

  • If you cannot talk, it is not a long run.
  • Do not add a hard workout the next day.
  • Do not double mileage because a plan PDF said so.
  • Bonking until you stagger is not toughness. Eat.
  • Chest pain, fainting, a calf that pops: stop and a person.
