Long Run Challenges: More Common Than You Think

Nothing saps motivation faster than setting out for a long run only to feel like you’re dragging before you even settle into your stride. It’s frustrating—and that struggle can taint your overall training mood. The reality is, however, that a tough long run doesn’t necessarily mean you’re losing fitness or need to abandon your race goals. “You can take comfort in knowing that several factors can contribute to a challenging long run,” says Amanda Katz, a certified run coach and host of the [Running Explained Podcast](https://www.runningexplained.com/podcast). “It’s not a reflection of failure.”

Assessing Your Pre-Run Nutrition

One critical element that often gets overlooked is nutrition. Snacking on high-fat or high-protein foods right before you lace up can wreak havoc on your gastrointestinal system, slowing you down significantly. Amanda Wagner, a registered dietitian and fellow certified running coach, emphasizes the impact of pre-run fueling choices. For example, opting for a handful of nuts instead of a quick carb source could lead to discomfort because fats and proteins take longer to digest. Many runners make the mistake of rushing out the door after a quick bite, often comprised of whatever’s lying around—think leftover breakfast from the kids. This hasty approach can lead to energy crashes or nausea, making those long miles feel even longer. As Wagner points out, finding the right balance in pre-run snacks can be your secret weapon. Aim for easily digestible carbohydrates—applesauce packets or graham crackers work well—anywhere from 20 to 60 minutes before hitting the pavement. If you have more time, integrating some protein and fat into your meal can enhance satiety.

Timing Your Fuel During the Run

Equally important is when you decide to start refueling mid-run. Waiting too long to take your first gel can leave you struggling to replenish your energy stores, making it tough to maintain your pace. Wagner suggests starting your fueling strategy early—within the first 20 to 30 minutes of your run. This proactive approach serves as a preventive measure against energy depletion. Remember, it’s not just a one-time deal. To keep your energy levels stable during runs longer than an hour, you should aim to take in 30 to 60 grams of carbohydrates per hour. A position statement from the [Journal of the International Society of Sports Nutrition](https://www.tandfonline.com/doi/pdf/10.1186/1550-2783-5-17) supports this guideline.

Consider Your Emotional and Physical State

If long runs regularly leave you drained or you dread them, it may indicate you've set the bar too high. According to Katz, the intensity of your runs should allow you to converse comfortably; if not, pacing adjustments may be in order. Slow down until you hit a level where the effort feels manageable—about a 3 on a scale of 1 to 10, where 10 is max effort. Also, be mindful of external life stressors. Major responsibilities, from work obligations to personal relationships, can affect both your physical and mental readiness. If you’re juggling numerous commitments, it’s perfectly acceptable to tailor your training. Implement strategies like walk breaks, reduce the intensity of your runs, or even consider a deload week to prevent burnout. This holistic approach to your long run preparation and recovery can help clarify whether those struggles are momentary hurdles or signs of a more deeply embedded issue. If you consistently find yourself feeling gassed after multiple long runs, it may be worth consulting a professional to investigate possible nutritional deficiencies or stressors that could be hindering your performance. If you're finding yourself doubting your strength or stamina on your long runs, it may be time for a reassessment. Whether it’s adjusting your approach to fueling, pacing, or addressing the stresses in your life, recognizing these challenges is the first step toward overcoming them.
