At identical VO2max, some runners are 30 percent more efficient. Cadence tuning, running drills, and tendon training turn your form into an efficient machine.
## Introduction At the pro level, getting faster comes down to two things: physiological capacity and mechanical efficiency. While VO2max (your maximum oxygen uptake) and lactate threshold define your absolute metabolic ceiling, running economy (RE) determines how much of that ceiling actually translates into speed on race day.
The decisive number: among elite runners with nearly identical VO2max values, running economy varies by up to 30 percent. Two equally powerful engines — one burns almost a third more fuel for the same pace.
This difference is determined above all by modifiable biomechanical factors: spatiotemporal parameters, joint kinematics, and ground reaction forces (GRF). If you want to get faster at the highest level, you can't just train the cardiovascular system — you have to turn your running form, through advanced running drills and neuromuscular strength training, into a highly efficient machine that reduces vertical oscillation, minimizes braking forces, and maximizes the elastic energy return of the Achilles tendon.
## What You Need - Flat practice stretch: A tartan track or a hard, level asphalt path (20–50 meters) works best for clean running drills. - Running watch with cadence measurement: Essential for monitoring your step frequency in real time and manipulating it deliberately. - Camera / smartphone: For a biomechanical video self-analysis of your posture and foot strike (ideally in slow motion).
### 1. Eliminating Braking Forces (Cadence Tuning) The biggest energy loss for distance runners comes from "overstriding" — landing the foot far ahead of your own center of mass. This mistake acts like a pulled handbrake with every step.
To fix this and reduce impact forces, clinical biomechanics analyses recommend deliberately increasing your preferred step frequency (cadence) by 3 to 5 percent — just a few more steps per minute. Shorter, quicker steps make the foot land automatically flat (midfoot) and exactly under your center of mass, and impact energy converts directly into forward propulsion.
### 2. Neuromuscular Programming Through Running Drills To reprogram inefficient movement patterns, you break the movement down into its components and train them in isolation. Do a precise set of running drills three to five times a week (after an easy warm-up jog): - Ankling: Trot with small steps and high frequency, moving almost exclusively from the ankle joint. The knee of the standing leg stays straight. This trains the reactive push-off phase and minimizes ground contact time. - Skipping & butt kicks: For butt kicks, you dynamically kick your heels up toward your glutes. For skipping, you drive your knees up at maximum frequency. Both train intermuscular coordination and strengthen the thigh muscles for better running economy.
### 3. Neuromuscular Conditioning and Tendon Stiffness Biomechanical efficiency needs tissue that functions like an extremely strong spring. The science is clear: heavy, explosive resistance training must be a fixed part of the program for distance runners.
Squats, lunges, or plyometric jumps improve tendon stiffness and motor unit recruitment. Only then do your tendons optimally release the energy absorbed at foot strike back as forward propulsion.
### 4. Aligning the Kinetic Chain Always pay attention to your entire body axis. Your torso leans slightly forward, but stays absolutely upright. Shoulders stay relaxed, arms swing parallel to your direction of travel at roughly a 90-degree angle — the classic right angle between upper arm and forearm. Bring your center of mass optimally over your foot strike, so force transfers cleanly.
## Common Mistakes - "Sitting while running" (collapsing at the hip). Letting the pelvis tilt backward is a serious mistake. Running feels extremely hard and you get pulling in the lower back. Correction: stand tall, lift the sternum, activate the core. - Heel strike far ahead of the body. Landing on the heel with the leg stretched far forward jams the joints and massively reduces running economy. Fix: pull the foot under your center of mass. - Overdone arm action. If the arms cross in front of the chest or bend too sharply, you lose rotational energy that would otherwise efficiently support your leg action. Correction: swing in a straight line beside the body.
## Safety Notes A sudden, radical technique change (e.g. forcing a switch from heel to forefoot strike) puts enormous strain on the calf and Achilles tendon. Increase cadence and the volume of running-drill exercises only in small, gradual steps.
Also never perform technique drills in a heavily fatigued state at the end of a hard interval session — fatigue inevitably leads to sloppy execution and faulty neuromuscular adaptations.
## Pro Tip Actively focus on the so-called pulling phase while running. Lift the extended leg and try to get ground contact again as quickly and directly as possible after the flight phase.
Imagine actively pulling the ground backward underneath you (like a scratching motion) — this drastically minimizes braking forces at the moment of impact and significantly boosts your forward dynamics with each stride.
### How do I measure my own running economy? Without a lab, only indirectly: track your heart rate and perceived effort at the same pace over several weeks. If your heart rate drops at identical pace, your economy is improving. A running watch with cadence and vertical oscillation tracking adds useful data points, but it's no substitute for real lab testing with oxygen measurement.
### Do I need to consciously think about cadence on every run? No, only during the transition phase. Drill the higher frequency deliberately in short blocks or during running drills until it becomes automatic — that usually takes several weeks. After that, the adaptation runs in the background, freeing you to focus fully on pace and race tactics again.
### How often should running drills be part of my training? Three to five times a week, right after your warm-up jog and before the main session. Important: never at the end of an exhausting workout — fatigue leads to sloppy execution and ends up drilling in exactly the faulty patterns you're trying to eliminate.
### Is running drills alone enough, or do I need strength training too? Running drills alone aren't enough. They reprogram your movement patterns, but the tendon stiffness needed for elastic energy return only comes from heavy or plyometric resistance training. Combine both: drills for coordination, squats and jumps for the structural strength of your tendons and muscles.
### What does better running economy actually get me on race day? At the same VO2max, a 10 percent better running economy means noticeably more speed at the same effort — or the same speed at noticeably less effort. Over a marathon, that often adds up to several minutes' difference, without your maximum oxygen uptake changing at all.
