The long run is where good runners are built.
It’s the workout that differentiates the runners who toe the line on race day feeling fantastic from those who crumble mile 18. nail your long run and the rest of your training falls into place.
But here’s the problem…
The majority of runners approach the long run all wrong. They go out too fast, forget to eat, and wonder why mile 10 feels like sucking wet cement.
The best news? Running your long run is simple. There are just three concepts to understand: fueling, pacing and recovering.
Here's what's inside:
– Why the long run is different from every other workout
– How to fuel like a smart runner (not a nervous one)
– The pacing trick that changes everything
– The recovery windows most runners miss
– Small habits that add up to big gains
Why The Long Run Deserves Its Own Playbook
The long run isn’t just a longer easy run. It’s a totally different beast.
Going long causes your body to transition from burning fast carbohydrates to fats. Your slow twitch muscle fibers are challenged. Your cardiac muscle chambers enlarge. Your mitochondria increase in number.
That’s why treating a long run like a short run will always backfire.
The cool part is recovery tools have evolved to meet this need. Runners are spending time in an oxygen chamber for wellness treatments weekly. If longevity is what you seek when training without injury, look into researching a hyperbaric oxygen chamber for sale. They force additional oxygen into your body which can assist with the kind of deep muscle recovery your long run requires.
Recovery aside, everything starts with fuel.
Fuelling Your Long Run The Right Way
A little known fact among runners: during exercise that extends beyond 60-90 minutes, glycogen stores become depleted.
Translation? If you don’t fuel, you’re going to bonk.
Bonking isn’t just painful. It sabotages your workout, your recovery, and your confidence for your next long run.
Here’s a simple fuelling plan that works for most runners:
Before the run:
– Eat a proper meal 2-3 hours before
– Focus on easy carbs and small amounts of protein
– Avoid anything heavy in fibre or fat
During the run:
– 30-60g of carbs per hour for runs over 90 minutes
– Sip water regularly, don’t wait until you’re thirsty
– Add electrolytes if it’s hot or you’re a heavy sweater
After the run:
– Get some carbs and protein in within 30-60 minutes
– Rehydrate properly – keep drinking through the day
– Eat a proper meal within 2 hours
One recent report noted that elite ultrarunners consumed 100g per hour on average during the 2025 Western States 100. That’s a lot of food and fluid. You have to train your gut to digest it. Ease into it over weeks.
Fueling is not something you try on race day. It’s something you practice during training. Fuel on EVERY long run.
Pacing: The Silent Performance Killer
Pacing is where most runners lose their long run before they even start.
Everyone knows the feeling. Mile one felt great… You push. Mile two felt good… You push harder. Mile eight you’re dying thinking what went wrong.
Here’s the fix:
Start slower than you think you should.
Ideally your long run pace should be dull for the first 3-5km. This isn’t a run where you test yourself. This is a run to build your aerobic engine for those hard races.
A good rule of thumb:
– Easy long run: 60-90 seconds slower than goal race pace
– Progression long run: Start easy, finish at goal pace
– Marathon pace long run: Only during peak training blocks
Pacing tools like GPS watches help. But even better?
Learn how to gauge your effort. Can you talk in complete sentences? Great, you’re at the right place. Can’t breathe? Ease up. Your legs will feel better tomorrow.
The Recovery Windows That Actually Matter
Recovery is where the magic happens. Not on the run itself.
Most runners assume recovery means “sit on the couch”. However there are prime windows where your body is ready to accept everything you throw at it. If you miss them you lose opportunities.
The first window - 30 to 60 minutes after finishing.
This is the ideal window for refuelling. Your muscles are literally crying out for carbohydrates and protein. Eat at this time.
The second window - 4 to 12 hours after.
Your body is constantly repairing itself. Focus on eating right, drinking water, and gentle exercise.
The third window - overnight.
Sleep! It’s the best recovery mechanism there is. Get 8-9 hours the night following your long run. Growth hormone levels soar while you’re in deep sleep and that’s when the magic occurs.
FYI, it takes approximately 24 hours to completely restore glycogen levels after a strenuous long run. It’s not instant. So what you eat on Sunday is just as important as what you eat after your run on Saturday.
FYI… GI distress is prevalent among endurance athletes. Approximately 1 in 4 recreational runners experience GI symptoms while racing. That’s why fueling practice is imperative in training.
Small Habits That Compound
Fastest improving runners aren’t experimenting with outrageous stuff. They’re just doing little things, day in and day out.
Try these habits on for size:
– Foam roll for 10 minutes after every long run
– Take an ice bath or contrast shower once a week
– Track your sleep, not just your mileage
– Add strength training twice a week
– Take an easy day (or full rest day) after every long run
None of these are revolutionary. But they do combine to make a runner who shows up healthy, week after week.
The secret is choosing two exercises and sticking with them correctly. Frequency over intensity always wins.
Bringing It All Together
The perfect long run isn’t about doing anything extreme.
Fuel properly before, during and after. Proper pacing like tomorrow’s run is more important than today’s. Recovery is no joke – all 3 windows.
Do this often enough and you’ll be amazed at how rapidly things can improve. Quicker pace. Less chance of injury. Long runs that seem possible, not horrible.
Fast runners don’t just train the hardest. They know how to train smart, eat smart and recover smart.
Now lace up and get after it.
