How to Keep Good Running Form on Your Long, Slow Runs

Ever found yourself halfway through a long, slow run and realized your stride has turned into a shuffle? Maybe your shoulders are creeping up to your ears, your arms are flapping, or your feet are slapping the pavement. I know that feeling—when you start strong, but as the miles add up, good running form starts to slip away. It’s one of those sneaky issues that can leave you feeling more tired than you should be, and sometimes even lead to nagging aches you didn’t sign up for.

It’s easy to think that form only matters when you’re running fast or chasing a personal best. But the truth is, your form on those long, slow runs can make or break your running experience. I’ve seen so many runners (myself included) lose focus on form during easy miles, only to pay for it later with sore hips, stiff backs, or just plain sluggishness.

Here’s how to keep your form strong—even when the run is slow and the miles are long:

• Check In Regularly: Every mile or so, do a quick scan from head to toe. Are your shoulders relaxed? Arms swinging gently by your sides? Feet landing under your body?
• Keep Your Posture Tall: Imagine a string pulling you up from the crown of your head. This keeps your chest open and helps you breathe easier.
• Shorten Your Stride: As you tire, your stride can get sloppy. Focus on landing softly with a slight bend in your knee—think quick, light steps instead of big, heavy ones.
• Relax Your Hands and Face: Clenched fists and a tense jaw waste energy. Shake out your hands and give your face a gentle smile (yes, even if you’re faking it!).
• Use Your Core: A gentle brace in your midsection helps support your back and keeps your hips from wobbling.

I’ve made it a habit to pick a mental cue for each run—sometimes it’s “tall and relaxed,” other days it’s “quick feet.” It’s amazing how a simple reminder can reset your form and help you finish feeling stronger. And if you want to dive even deeper into making running feel easier, you’ll find more tips and step-by-step advice on making running feel easier and more enjoyable.

Long, slow runs are where you build endurance and mental strength—but they’re also the perfect time to practice the habits that make running feel smoother every day. Listen to your body, keep your form in check, and you’ll finish those miles feeling better than you started.
