The Long Run Podcast: A Crucial Part Of Distance Running Training

If you’re training for a distance event, the long run is the single most important session in your entire training plan. Get it right, and race day becomes manageable. Get it wrong, and even the best intentions can unravel fast.

If you’re training for a distance event, the long run is the single most important session in your entire training plan. Get it right, and race day becomes manageable. Get it wrong, and even the best intentions can unravel fast. Have listen to the podcast here Why the Long Run Is So Important in Marathon Training The long run is more than just a slow jog covering extra miles. It’s a practice race. Every successful distance race I’ve ever run has been built on consistent, well-planned long runs. When those runs went well in training, race day followed suit. When they didn’t, the outcome was usually inevitable. The long run develops: Aerobic endurance Muscular resilience Mental toughness Confidence A repeatable race-day routine If you’re training for a half marathon, your long run prepares you for sustained effort. If you’re training for a marathon, it teaches your body how to keep moving when fatigue sets in. How Long Should a Long Run Be? This depends on your race distance: Marathon Long Run Distance Most runners peak at 18–20 miles Some experienced runners go up to 22 miles Going further rarely adds benefit and increases injury risk Half Marathon Long Run Distance Typically 10–12 miles Enough to feel confident without overloading the body Your longest long run should feel like 80–90% of race-day demand, not a full race effort. Everything in Your Training Plan Builds Toward the Long Run Your midweek runs are not random. They exist to support the long run. If your long run is approaching 18–20 miles, your midweek runs should typically be 8–10 miles, not short recovery jogs. Gradual mileage build-up is essential for adapting your heart, lungs, and legs. Key principle: 👉 You cannot jump from short runs straight to long runs and expect it to work. Timing Your Long Run Like Race Day To get the most out of marathon training, treat your long run as a dress rehearsal. If your race starts at 9–10am, aim to run long runs in the morning Practice waking up, eating, and running at race-like times Avoid late-afternoon long runs that disrupt recovery Morning long runs also reduce stress and give you the rest of the day to recover properly. Long Run Nutrition: Practice Exactly What You’ll Do on Race Day Nutrition is one of the biggest reasons runners struggle late in races — and it should never be improvised. The Night Before Plan a carbohydrate-based meal Eat early enough to digest properly Don’t leave food choices to chance Race-Morning Breakfast (and Long Runs) Eat the same breakfast every time Simple foods work best (e.g. tea and toast) Avoid heavy or unfamiliar meals If you wouldn’t eat it on race day, don’t eat it before a long run. Using Gels on Long Runs: When and How Gels are a game-changer for longer distances — but only if you practice with them. When to Start Using Gels Begin experimenting once long runs exceed 10 miles How Many Gels Do You Need? Marathon-distance long runs: usually 3–5 gels Always take water with gels to help digestion Key Advice Try different brands in training Stick with what works for you Never try gels for the first time on race day Fuel belts are often the most practical way to carry gels and water. Carrying bottles in your hands can affect posture and cause shoulder discomfort over long distances. Hydration Strategy for Long Runs Hydration becomes critical once runs stretch beyond two hours. Options include: Using a fuel belt with bottles Planning looped routes with water drops Placing bottles along your route in advance Big races provide water stations, but long runs don’t — so you must plan ahead. Gradual Progression: The Golden Rule of Long Runs One of the most common causes of injury in marathon training is increasing long runs too quickly. Safe Progression Guidelines Increase distance by around 1 mile at a time Never jump from 10 to 14 miles in one week Feeling good today doesn’t mean doing more today If you miss a week due to illness or injury, don’t skip ahead. Adjust the plan and rebuild gradually. Consistency always beats big single efforts. How Far Do You Really Need to Run Before a Marathon? Most runners will finish a marathon comfortably if they reach 18–20 miles in training. Crowd support can help on race day — especially in major events — but it won’t carry you through an underprepared final six miles. Smaller races often have limited support, so your training must do the heavy lifting. Longer long runs improve: Physical readiness Mental confidence Your ability to cope when things get tough When It’s Okay to Stop a Long Run Early Long runs are important — but they’re not untouchable. If conditions are terrible, you feel unwell, or something is clearly wrong, it’s sometimes better to stop, recover, and rework the plan than to force a bad session. That said, don’t quit at the first sign of discomfort. Learning to push through rough patches is part of endurance training. Rest Days Are Non-Negotiable This is crucial: Never do a long run while tired. Rest the day before Rest the day after Let your body absorb the training Recovery is not optional. It’s a core part of marathon and half marathon training. Final Thoughts: The Long Run Builds Your Race Your long run shapes how race day feels — physically and mentally. Every run in your training plan supports it. Every decision around nutrition, timing, and recovery feeds into it. When long runs go well, races usually do too. Have a listen to the podcast here
