The long run
Also called long run · weekend long run · time on feet · sunday long run
Community talk. May contain inaccuracies. Not medical, training, or diet advice. Sharp pain, fainting, or disordered-eating concerns need a clinician.
A long run is one of the longest running sessions in a runner’s week. It offers practice staying on your feet longer, often for a distance event. Some stay easy throughout; others contain planned faster sections. Length and effort both matter.
London Marathon · 202601
What the session involves
Long is relative to the week. Hal Higdon’s Novice 10K puts its longest run on the weekend, starting at 3 miles and reaching 5.5. Its distances illustrate one beginner schedule, not a minimum everyone must reach.
Hal Higdon · undatedFaster sections can be planned. London’s 2026 advanced marathon plan includes a 12-mile long run ending with 4 miles at marathon pace. That example belongs to experienced marathoners, not every long run.
London Marathon · 2026Easy versions allow conversation and walking. Higdon’s novice schedule keeps running conversational, permits walk breaks, and places rest around the weekend. Longer duration still creates fatigue even at a comfortable pace.
Hal Higdon · undatedShoes, a route and a time window are the basics. The NHS lists comfortable running clothes, running shoes, a timer and water, especially for longer or warmer outings. A watch is useful for timing; specialist tracking is optional.
NHS · undatedFuel amounts depend on duration and tolerance. AIS guidance lists 30–60 grams of carbohydrate per hour for endurance exercise lasting 1–2.5 hours, from drinks, ordinary food or sports products. This is sports-nutrition context, not an automatic gel schedule for a beginner outing; gut comfort and hydration also matter.
Australian Institute of Sport · undatedDistance can hide a very different time commitment. At an illustrative steady pace of 6 minutes per kilometre, 10 km takes one hour; at 9 minutes per kilometre, it takes 90 minutes. Stops add time to either outing. The same distance therefore leaves different demands on the calendar and route planning. These paces illustrate duration, not a speed target or a rule for fueling.
Illustrative calculation02
Why runners make room for it
It rehearses sustained effort. Coach Greg McMillan uses long runs to develop endurance and familiarity with fatigue. That is a training purpose, not proof that one weekly outing guarantees fitness or a race result.
McMillan Running · 2005Race preparation includes practical experiments. McMillan’s race rehearsals include clothing, shoes, food and drink. Discovering chafing, inconvenient pockets or an unappealing gel in training can be more useful than chasing a faster split.
McMillan Running · 200503
Good to know before adding more
A big jump in one outing can matter. A 2025 study of 5,205 runners linked runs more than 10% longer than their longest in the preceding 30 days with higher overuse-injury rates. It was observational, mostly male, and did not establish a guaranteed safe increase or validate a universal weekly percentage rule.
British Journal of Sports Medicine · 2025Pain and fainting are not endurance targets. The NHS says to stop when something feels wrong. Sharp pain, fainting or disordered-eating concerns need a clinician; a longer run is not a reason to override symptoms.
NHS · undated04
What long runs are like in practice
Forty minutes can already feel long. Beginner accounts describe 40–70 minutes and, after Couch to 5K, gradually lengthening one day. Some mention additions of 5–15 minutes, not a universal progression. Marathon talk often means 16–20 miles; paired long days belong to ultra discussions. These are different workloads, not a ladder everyone must climb.
CommunityWalk breaks can be deliberate. Some reports use 9 minutes running and 1 walking; others walk hills or in heat. Runners also describe stiff opening miles, an enjoyable middle and a hungry final 15 minutes. Recording time on feet means recording duration rather than judging every mile’s pace.
CommunityThe 20–30% rule gets argued over. In r/AdvancedRunning, some use that share of weekly mileage, while others say race distance, training days and recent volume change its usefulness. One runner even reported a 50-mile week with no distinctly long outing. A percentage does not settle the session’s purpose.
Community · Reddit · r/AdvancedRunningA coach’s percentage is not a finding for everyone. A TrainerRoad poster recalled BarryP’s running advice: under half the week, ideally 30–35%, to protect consistency. Other replies questioned whether the cycling podcast’s 50% observation applied across volumes or reflected race recovery. The running advice was secondhand; the analysis was correlational.
Community · TrainerRoad · 2026Easy can feel awkwardly slow. A new runner reported 180 bpm at 6:30/km. TrainerRoad replies offered a mile running plus a minute walking, a slower shuffle, or checking watch fit. They disagreed about the cause; forum replies cannot diagnose a heart-rate reading.
Community · TrainerRoad · 2024Food has to be affordable, tolerable and carryable. In r/XXRunning, runners debated fueling beyond 60 versus 90 minutes, gel expense and textures. Options included candy and stroopwaffel pieces. One runner’s two 10-ounce bottles needed a fountain refill on an outing over three hours. Carrying supplies and knowing refill access were practical obstacles, not just nutrition numbers.
Community · Reddit · r/XXRunningEating more does not fix every lost afternoon. A runner worried about doing Halloween activities after 12 miles despite fueling during the run. Replies described better afternoons after meals or slowing down, but others remained exhausted despite improving food, hydration and sleep. One reported that even 70-mile weeks did not make 12 miles effortless.
Community · Reddit · r/Marathon_TrainingA sustainable weekend matters more than a heroic outing. Reports mention setting aside a morning, meeting friends, choosing a loop with an early exit and leaving the next day easy or free of training. Groups help attendance but can pull the pace upward; treadmill runners watch shows to ease boredom. When other commitments intervene, some choose a shorter outing they can fit into the day. Over a training block, an outing that once felt long can become familiar.
CommunityBonking describes an energy crash. Runners use the word for a pronounced loss of energy during a long effort. Reports mention gels or ordinary snacks after roughly 60–75 minutes, with no shared dose. Warnings about chest pain or a sudden calf pop describe different concerns from tiredness. An energy crash is not a toughness requirement or a diagnosis.

- what People Say
- The job: Teach the body and the brain that they can keep going. [community]
- r/running treats the long run as sacred and then tells people they went too fast. [community]
- Time-on-feet is the phrase when pace is a trap. [community]
- New runners: 40 minutes can be a long run. It does not have to be 12 miles. [community]
- Marathon discussions often describe 16–20-mile long runs. Some are entirely easy; others contain planned faster segments, so distance alone does not describe the session. [community]
- “Bonking” is runners’ shorthand for a pronounced loss of energy during a long effort, often discussed alongside duration and fueling. [community]
- Social long runs (run club) are how people keep it. They also go too fast in a pack. [community]

- After Couch to 5K (C25K), people may gradually make one running day longer than the others. [community]
- Back-to-back long days are an advanced ultra trick, not week four. [community]
- how People Run It
- Pick one day with nothing hard after it. [community]
- Start slower than they think. First miles are a warmup. [community]
- Carry water / a snack once they are out over an hour. [community]
- Hills and heat: they walk. The long run still counts. [community]
- They do not check the 5K split. [community]
- Next day is easy or off. Legs will vote. [community]

- Share of the week people quote: about 20–30% of weekly mileage. [community]
- Add: 5–15 minutes a week, not a sudden doubling. [community]
- Walk breaks: as needed. Some use 9 run / 1 walk on purpose. [community]
- Fuel talk after ~60–75 min: a gel or a real snack. Individual. [community]
- how People Keep It
- A weekend morning that is already protected. [community]
- A loop they can cut short if it goes wrong. [community]
- A friend slightly slower than their ego. [community]
- A recovery meal they like. [community]
- They write the time, not the pace. [community]
- how It Feels
- Miles 1–2: stiff, doubtful. [community]
- The middle: this is why people become runners. [community]
- The last 15 minutes: honest. Character, or a snack, or both. [community]
- Afternoon: sleepy and proud. Or wrecked if they raced it. [community]
- Tuesday after a too-fast long: the week is already lost. [community]
- A good cycle: the old long run is now a medium day. [community]
- how Long People Run It
- Most weeks of a running year. [community]
- They taper it before a race. [community]
- In a cut or a hot month: they hold time and slow down. [community]
- After injury: they rebuild duration before pace. [community]
- deep Dive
- Length defines the session: easy long runs and long runs with planned quality work both appear in training discussions. The plan and runner’s context distinguish them. [community]
- Quality within a long run: some plans include faster segments; others keep the whole session easy. That difference belongs in a report before comparing its distance with another runner’s. [community]
- Rucking a long day is a different tax. See Rucking. [community]
- C25K graduates grow one day. They do not jump to 10 miles. [community]
- A run club adds a social setting. The group’s pace and the individual runner’s intended effort still need to match for the session to mean the same thing. [community]
- watch For Long
- Effort and length are separate: many long runs are conversational, but some plans include faster portions. A harder segment does not stop the session being a long run. [community]
- Do not add a hard workout the next day. [community]
- Do not double mileage because a plan PDF said so. [community]
- Bonking until you stagger is not toughness. Eat. [community]

Read the preserved reader notes
- definition
- A long run is the longest or one of the longest running sessions in a person’s current training week.
- community Picture
- 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.
- additions
- text
- 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.
- sources
- guide
- what
- The moving part is length relative to the rest of the week, not a fixed distance. On Hal Higdon's novice 10K and half-marathon pages, the long run is the weekend session, longer than the midweek runs, with rest or easy cross-training beside it. The 10K Sunday starts at 3 miles. The half table starts at 4, and the longest training day is 10. A shorter week can have a shorter long run.
- These pages describe an easy long run. The 10K novice is told to converse comfortably and not chase speed. The half page says the same, and adds about 65 to 75 percent of maximum pulse for people using a monitor. Neither plan puts a fast section in the long run. Walking breaks are allowed. Taking one does not cancel the run.
- It is not a tempo and not a race. The instruction is to go slow and cover the distance. Racing the miles turns it into the hard day.
- how
- Pick a day with nothing hard after it. Both plans use Sunday, with Monday and Friday as rest. Saturday can be the long day if Sunday is not free. Start slower than the pace the rest of the run will use. The opening still counts.
- Follow the week's row. The novice 10K Sunday goes 3, 3.5, 4, 4, 4.5, 5, and 5.5 miles, then the race. The half Sunday goes 4, 4, 5, 5, 6, a 5K, 7, 8, a 10K, 9, and 10 miles, then a shorter week and 13.1. His prose says that long run builds from 3 to 10 miles. The table starts at 4. Use the row. Come close. The course can be approximate.
- Carry a drink when thirst shows up, and more in heat. The NHS Couch to 5K page, for shorter sessions, says to take water on warmer or longer runs and names a light snack such as a banana or toast one to two hours before. These Higdon pages print no gel dose and no minute when fuel is mandatory. Practice a familiar drink or snack rather than a new one late.
- Walk hills when speech goes. The run still counts. Do not score it by a 5K split. The next day stays easy or off. If the week shrinks, a medium-long finish beats a much longer run that wrecks the days after it.
- understand
- Higdon calls the long run the key to the half because that distance grows while midweek runs stay narrower. Rest before and after is how the growth stays repeatable. Intervals the next morning remove that rest. The increases written here are half-mile and one-mile steps, not a doubling copied from another plan.
- Some race plans put faster miles inside a long run. These two novice pages do not. Distance alone does not say the run was easy. The report has to say whether pace stayed conversational. The half page's 3-to-10 sentence and its 4-mile first Sunday are both on the page.
- No grams-per-hour fuel number is on the pages used here. Chest pain, fainting, a calf that pops, sharp pain, or eating that has become rigid or punishing is the point to stop and see a clinician. Running until empty is not required. The notes below are how long runs felt, not a new peak.
