Common Sprinting Mistakes

The 5 Sprinting Mistakes That Are Slowing You Down

I’ll never forget watching Sarah, a promising high school sprinter, straining her neck forward as if trying to cross the finish line with her chin. She was fast, but she was fighting herself. The moment we corrected her head position, she shaved two-tenths of a second off her 100m time. Just like that.

That's the thing about sprinting. It’s raw, explosive power, but it’s also a precise skill. The smallest mistakes create massive drag, waste energy, and keep you from the personal best you're chasing. Let's break down the most common culprits I see every day on the track.

Mistake #1: The Brake Job (Overstriding)

Picture this: a runner reaching their foot way out in front of their body, heel striking the ground with a thud. It looks powerful, but it’s a classic brake job. That foot hitting the ground ahead of your center of mass actually slows you down with every single step.

The Fix: Focus on landing your foot directly under your hips. Think "pawing" the ground backwards, not reaching for it. You want to feel like you're applying force into the track behind you, propelling yourself forward.

Mistake #2: The T-Rex Arm Swing

I see so many runners with tight, tense arms, elbows flared out, hands swinging across their body. This isn't just an upper-body issue. That wild, inefficient arm motion twists your torso and kills your forward momentum.

The Fix: Your arms are for rhythm and balance. Keep your hands relaxed (imagine holding a delicate potato chip), elbows bent at about 90 degrees, and drive them straight forward and back. Your right hand should come up to about cheek level as your left leg drives forward, and vice versa.

Mistake #3: The Panicked Gasp (Poor Breathing)

When the pain sets in at 70 meters, the first thing to go is controlled breathing. It becomes shallow, panicked, and held in the chest. Without oxygen fueling your muscles, you're running on fumes for the last third of your race.

The Fix: Practice rhythmic, diaphragmatic breathing. In through the nose, deep into the belly, and a controlled exhale out through the mouth. Find a pattern that works for you (like a 2:2 inhale-to-exhale ratio) and drill it in practice until it's automatic.

Mistake #4: The Head Bobble

Remember Sarah? Any excessive movement that isn't forward is wasted energy. Bobbing your head up and down or side to side is like driving with the parking brake slightly engaged.

The Fix: Imagine your head is a marble on a plate. You want to keep it perfectly still and neutral, with your gaze focused about 20-30 meters down the track. A stable head leads to a stable torso and a more efficient stride.

Mistake #5: The Standing Start

Many athletes explode out of the blocks... and then immediately stand straight up. You've just sacrificed all the powerful forward lean you worked so hard to create.

The Fix: Drive out low and maintain that aggressive forward lean for the first 20-30 meters. You should gradually rise into your full upright sprinting posture, not pop up like toast.

Quick safety note: these are technical cues, not medical advice. If you're new to sprint training or coming back from an injury, check in with a coach or physician before adding hard sprint work to your routine.

Quick Fix FAQs

How can I tell if I'm overstriding?

Film yourself! A quick video from the side is the best coach. If your foot is clearly landing in front of your knee, you're overstriding. Your shin should be nearly vertical at foot strike.

My shoulders get so tight when I sprint. Why?

This is almost always a symptom of Mistake #2, the T-Rex arms. That tension from flared elbows and tight fists travels right up into your neck and shoulders. Relax your hands and focus on driving your elbows back.

Is it better to breathe through my nose or mouth?

When you're going all-out, you need maximum oxygen. Inhaling through the nose and exhaling through the mouth is a great technique, but the most important thing is that you're taking deep, full breaths. Don't restrict your air intake.

How long will it take to fix these mistakes?

Awareness is the first step. You'll see immediate improvement in feel by focusing on one thing at a time. But to truly rewire muscle memory, dedicate 10-15 minutes of your practice, 2-3 times a week, to drill work. Consistency is key.

The track doesn't lie. It shows you exactly what you're doing right and what's holding you back. Work on these five areas, and you’re not just running harder—you’re running smarter. Now get out there and apply force.
