Introduction: What Is Running Economy and Why It Matters
Running economy describes how efficiently your body uses oxygen at a given pace. Physiologists measure it as the oxygen uptake required to maintain a submaximal speed—typically expressed in milliliters per kilogram per kilometer. Think of it as your fuel efficiency rating: two runners with identical aerobic capacities can perform very differently if one uses less energy to cover the same ground.
This matters because running economy stands alongside VO2max and lactate threshold as a key determinant of endurance performance. Research suggests it can account for 25-30% of variance in race outcomes beyond those other factors. A modest 2-5% improvement in running economy might shave 1-2 minutes off a 20-minute 5K or 5-10 minutes off a 3-hour marathon.
This article focuses on non-medical, training-related strategies supported by sports science research from the 1990s through the 2020s. You’ll learn how biomechanics, running drills, strength training, footwear, and weekly planning can help you run faster with less effort.
The Science Behind Running Economy
In laboratory settings, researchers measure running economy by having athletes run on a treadmill at fixed speeds while wearing a mask that captures expired gases. The oxygen consumed at each speed reflects the energy cost of running that pace. Lower values mean better economy.
Several components affect this measurement. Biomechanics—your movement patterns—play the largest role, accounting for up to 40-50% of variance between runners. Neuromuscular coordination determines how quickly and efficiently your muscles activate. Muscle-tendon stiffness influences how much elastic energy returns with each stride. Cardiorespiratory efficiency supports the whole system through capillary density and mitochondrial adaptations.
Landmark research by Cavanagh and Williams in the 1980s-1990s established that trained distance runners can differ by 20-30% in economy at identical speeds, independent of VO2max. A 2004 review by Saunders and colleagues synthesized decades of data confirming this finding.
Consider two runners with the same VO2max of 60 ml/kg/min. The more economical runner might sustain marathon pace at 75% of their maximum capacity, while the less economical runner works at 85%—leading to faster lactate accumulation and earlier fatigue despite similar aerobic ceilings. Economy is also speed-specific and surface-dependent: track running typically costs 2-5% less energy than treadmill, while trails may require 5-10% more due to uneven terrain.
Key Factors That Influence Running Economy
Running economy is multi-factorial. Rarely does a single change produce dramatic improvements. Instead, gains come from addressing several elements over time.
The main modifiable factors include:
- Running form and biomechanics (posture, arm swing, ground contact patterns)
- Step rate and stride length optimization
- Strength and plyometric training for force production and elastic recoil
- Training volume and intensity distribution
- Body composition (approached cautiously and individually)
- Footwear characteristics and running surfaces
- Fatigue management and recovery quality
Following a structured course or training program can help runners systematically address these elements to improve running economy.
Individual responses vary considerably. Some interventions help certain runners more than others based on training history, injury background, and target race distance.
Running Form and Biomechanics
There is no single perfect form. However, economical runners tend to share certain traits that reduce wasted energy.
An upright posture with a slight forward lean from the ankles—not the waist—helps maintain forward momentum while minimizing braking forces. Proper running posture requires maintaining a tall stance with the head aligned with the body, which can lead to better running efficiency and comfort. When your upper body tilts from the hips, you create unnecessary deceleration with each foot strike.
Arm swing should remain compact and relaxed, moving front-to-back rather than across the body. When arms cross your centerline, your torso rotates excessively, wasting energy that could drive you forward. Keep hands near waist level, loose and unclenched.
Efficient stride mechanics involve landing with your feet close to your body’s center of mass rather than reaching far ahead. Avoid overstriding by ensuring your feet land directly under your hips to prevent braking forces. This reduces overstriding and the braking forces it creates. Economical runners also show lower vertical oscillation—less “bouncing” with each step—which saves 2-4% in energy cost.
Foot strike pattern (forefoot, mid foot strike, or rearfoot) matters less than many assume. Proper foot strike techniques involve landing mid-foot to evenly distribute impact and reduce strain, while paying attention to how your heels contact the ground can help with injury prevention. Research by Ogueta-Alday in 2014 found rearfoot strikers averaged slightly better economy than midfoot strikers at certain speeds. What matters more is reducing impact peaks and braking forces regardless of where your foot first contacts the ground.
To check your form, record slow-motion video on a track every 4-6 weeks. Look for excessive vertical movement, arms that cross your body, or a visible “sitting” posture that suggests hip drop. Good running form is the safest and most efficient way to run, and poor posture can lead to neck and shoulder aches.
Cadence and Stride Length
Cadence—steps per minute—relates inversely to stride length at any fixed speed. Increasing cadence can help improve running form, hip flexibility, and reduce injury risk. Trained runners typically maintain 170-185 steps per minute at marathon to 10K pace, compared to 160-170 for many recreational runners.
Research shows that increasing cadence by 5-10% from your baseline can reduce overstriding and vertical oscillation, often improving running efficiency by 1-3%. A faster cadence naturally shortens your stride, encouraging landing closer to your center of mass. Runners should aim to increase cadence and target a cadence of 170-180 steps per minute to enhance running efficiency and reduce knee impact forces.
To measure your current cadence, count steps for one minute during a steady-pace segment, or use a watch or metronome app. Most runners find improvements between 175-185 steps per minute, though this varies individually.
Rather than overhauling your stride immediately, experiment with small increases. During easy runs, try 30-60 second segments at 3-5 steps per minute above your baseline, repeated 2-3 times. Over several weeks, this faster cadence may begin to feel natural without conscious effort.
Drills to Refine Technique
Coordination drills improve neuromuscular efficiency, potentially reducing the energy cost of each step. Running form drills teach your nervous system to activate muscles more quickly and precisely.
Effective running drills include:
- A-skip: Focus on knee drive and thigh lift, reinforcing hip flexor activation. The A-skip drill helps ingrain the backward pulling motion important for running propulsion.
- B-skip: Emphasize foot strike timing and hamstring engagement. The B-skip drill emphasizes the backward pawing motion as the foot lands on the ground.
- High knees: Build vertical stiffness and quick ground preparation. High knees focus on the loading phase of running and help improve running efficiency.
- Butt kicks: Improve heel-to-butt recovery speed during swing phase. Butt kicks help condition and coordinate the glutes and hamstrings for a strong running stride.
- Ankling: Practice dorsiflexion and forefoot landing mechanics.
- Straight-leg runs: Develop stiffness with minimal knee bend. The straight leg run drill reinforces the pawing motion practiced in the A-skip and B-skip.
- Carioca (grapevine): Move laterally by crossing one leg over the other, then behind, in a rhythmic pattern. This drill engages stabilizer muscles and improves running stability by emphasizing the ‘one leg’ movement during sideways motion.
Drills should usually be done after a warm-up but before the bulk of the training session. Most runners can benefit from performing drills twice per week for optimal results. Drills can be performed almost anywhere with sufficient space, such as roads or fields, and typically require about 50 meters of unobstructed space.
Perform drills after 5-10 minutes of easy jogging and dynamic mobility work. Cover 10-20 meters per drill for 2-3 repetitions, 1-2 times per week. Prioritize smooth, light, rhythmic movement over speed. These aren’t sprints—they’re technique practice. Other drills like bounding or skipping variations can supplement this foundation as you progress.
Strength Training and Plyometrics for Better Economy
Stronger, more elastic muscles and tendons store and return more energy with each stride. Meta-analyses by Paavolainen (1999), Saunders (2006), and Barnes (2013) report 2-8% improvements in running economy from 6-12 weeks of resistance training performed 2-3 sessions weekly.
This section provides general information rather than rehabilitation protocols. Adjust loads to your experience and seek professional guidance if uncertain.
Heavy Strength Training
Heavy strength training uses relatively high loads with low repetitions to improve neuromuscular efficiency rather than building significant muscle size. The goal is teaching your whole body to produce force more effectively.
Key compound exercises include barbell squats, deadlifts, lunges, calf raises, and hip thrusts. A common pattern involves 2-3 sets of 4-6 repetitions at challenging but technically solid loads, performed 1-2 times per week and separated from hard running sessions.
Benefits for running performance include improved force production per stride, better posture maintenance under fatigue, and potentially lower relative effort at given paces. When your leg muscles can generate more force, running at any submaximal pace feels easier—you’re working at a lower percentage of your maximum capacity.
Plyometrics and Elastic Recoil
Plyometrics are explosive, jumping-type exercises that develop rapid stretch-shortening of muscles and tendons. They enhance the “spring” quality that makes efficient running possible—up to 80% of propulsion comes from elastic energy return rather than active muscle contraction.
Runner-friendly plyometrics include pogo jumps (emphasizing ankle stiffness), line hops (lateral stability), low box jumps (5-10cm height), and single-leg hops over short distances. These exercises can increase tendon stiffness by 15-20% and reduce ground contact time by 10-20 milliseconds.
Start conservatively: 2-3 sets of 8-10 ground contacts once per week, performed after a full warm-up on forgiving surfaces like track infield or grass. Progress gradually if no soreness or discomfort arises. Runners with bone or joint issues should consult a professional before adding high-impact work.
Training Structure: Mileage, Intensity, and Consistency
Running economy improves significantly from consistent, appropriately scaled training volume combined with mixed intensities. Longitudinal studies show economy gains of 5-10% over seasons of dedicated training among collegiate and club athletes.
Three main levers drive these improvements:
- Total weekly volume builds aerobic efficiency and muscle adaptations
- Distribution of easy versus hard efforts (often cited as 80/20) prevents overreaching
- Inclusion of race-pace or faster work teaches economy at target speeds
Sudden mileage spikes or excessive intensity can increase injury risk and fatigue, undermining potential gains. Progress gradually and include recovery weeks.
Easy Runs and Aerobic Volume
A foundation of easy, conversational-pace running helps your body perform submaximal work more efficiently over time. Most runners can gradually increase weekly mileage by roughly 5-10% per week, with regular easier weeks, while monitoring how they feel.
For newer runners, tracking “time on feet” rather than miles helps control stress while building running efficiency. Easy runs should genuinely feel easy—this keeps fatigue manageable and allows subtle, natural form refinements to emerge.
Consider a hypothetical runner building from 25 to 40 weekly miles over 3-6 months through consistent easy aerobic running. By month six, their heart rate at a 9:00/mile pace might drop 5-8 beats per minute—a clear sign of improved economy without any interval training or speed work.
Tempo Runs, Intervals, and Race-Pace Work
Tempo runs are sustained moderate-hard efforts, typically 20-40 minutes at “comfortably hard” intensity. Intervals involve shorter, faster repetitions with recovery periods between. Both teach your body to use oxygen more efficiently at faster speeds.
Example sessions include:
- 20-minute tempo at an effort you could maintain for about an hour
- 6 × 3 minutes at 5K-10K effort with 2-3 minute jog recoveries
- 4 × 5 minutes at goal marathon pace with brief walking breaks
Limit quality sessions to 1-2 times per week, balanced with easy running and rest days. The goal is to improve speed-specific economy without accumulating excessive fatigue.
Shoes, Surfaces, and External Factors
Equipment and environment can influence running economy meaningfully. While certain shoes and conditions may reduce energy cost, individual comfort and injury history remain equally important.
Footwear and Running Economy
Shoe characteristics including weight, midsole foam properties, and plate design affect energy return and running efficiency. Research since 2017 has examined “super shoes” with carbon plates and responsive foams, finding notable economy improvements of 4-6% for many runners.
Response to footwear is individual. Some runners perform better in simpler trainers due to comfort or stability preferences. Practical guidelines:
- Choose shoes comfortable at intended race pace
- Rotate 2-3 pairs when possible to vary loading patterns
- Test new models during training sessions before race day
- Focus on supporting your natural gait rather than chasing technology trends
Running Surfaces and Environmental Conditions
Energy cost varies across surfaces. Track running is typically most efficient, with roads adding 1-2% cost, treadmills 3-4%, and trails 5-10% due to uneven terrain and constant micro-adjustments.
Wind, heat, humidity, and altitude also affect apparent economy. Headwinds can add 2-5% energy cost; each 5°C above 20°C adds roughly 1% cost. When conditions challenge you, focus on effort rather than pace. Perform key economy-focused workouts on surfaces similar to your goal race whenever possible.
Reducing Injury Risk While Improving Running Economy
Reducing injury risk is a key part of improving running economy, allowing you to train consistently and perform at your best. By focusing on proper running form and incorporating targeted running drills into your training routine, you can boost running efficiency while minimizing the likelihood of common injuries.
Running drills such as butt kicks, high knees, A-skip, and B-skip are more than just warm-up exercises—they’re essential tools for reinforcing good running form and activating the muscles that drive efficient movement. These drills help you develop an upright posture, a strong arm swing, and a mid foot strike, all of which are linked to better running performance and reduced injury risk. For example, high knees and A-skip drills engage the hip flexors and core, promoting a stable, balanced stride and helping you maintain proper form even as fatigue sets in.
Strength training is another crucial component for most runners aiming to improve running economy and stay injury-free. Exercises that target the core, hip flexors, and supporting leg muscles build the stability and power needed for efficient running. A strong core keeps your body aligned, while robust hip flexors and glutes help absorb impact and propel you forward. This not only enhances running efficiency but also lowers the risk of overuse injuries like shin splints, which are common when muscles fatigue and form breaks down.
Cadence and foot strike also play a significant role in injury prevention. Adopting a faster cadence—typically above 160 steps per minute—reduces the impact forces on your legs by encouraging shorter, quicker steps and a mid foot strike. This adjustment can decrease the risk of injuries such as shin splints and stress fractures, while also making your stride more efficient. Focusing on landing with your feet beneath your body, rather than overstriding, helps distribute forces more evenly and supports better running economy.
Other drills, like B-skip and leg swings, further enhance coordination, balance, and muscle activation. These movements train your body to move efficiently and react quickly, reducing the risk of tripping or losing form during a run. Advanced runners often use these drills to fine-tune their technique and maintain good running form at higher speeds or longer distances.
A well-rounded training session might start with a dynamic warm-up, followed by running drills such as butt kicks, high knees, and A-skip to activate key muscles and reinforce proper form. Afterward, a strength training routine focusing on the core, hip flexors, and legs can build resilience and power. Ending with a cool-down and stretching helps maintain flexibility and aids recovery, further reducing injury risk.
To get started, most runners can incorporate one or two running drills into their weekly routine, gradually increasing the variety and intensity as their technique improves. Listening to your body and allowing for rest days is essential—overtraining can increase injury risk and undermine your progress.
Ultimately, improving running economy and reducing injury risk go hand in hand. By prioritizing proper running form, integrating running drills, and committing to regular strength training, you’ll not only run faster and more efficiently but also enjoy a healthier, more sustainable running journey. Consistent practice and attention to technique are the keys to unlocking better running performance and long-term success.
Practical Plan: How to Improve Your Running Economy Over 8–12 Weeks
This framework provides a starting point rather than a rigid prescription. Adjust based on your experience, schedule, and how your body responds.
Over 8-12 weeks, gradually layer form drills, strength work, easy mileage, and limited quality sessions. Many runners notice changes in how a given pace feels within this timeframe—familiar efforts feel easier, heart rates drop, or they maintain good form longer into runs.
Weeks 1-2: Establish baseline with 3-4 easy runs, one long run, drills 1-2x, strength 1x, and one tempo session.
Weeks 7-8: Progress to adding plyometrics, intervals, and 10-20% more volume. Include cutback weeks at weeks 4 and 8.
Track subjective markers: perceived effort at familiar paces, post-run fatigue, and ability to maintain form late in runs.
Sample Weekly Structure
A balanced week for an intermediate runner might include:
- Monday: Easy 8km with drills afterward
- Tuesday: Rest or very light cross-training
- Wednesday: Tempo run (20-25 minutes at moderate-hard effort)
- Thursday: Easy 6km plus core engaged stability work
- Friday: Strength session (squats, deadlifts, hip thrusts)
- Saturday: Easy 5km
- Sunday: Long run (90-120 minutes at conversational pace)
Attach drill work to easy or quality runs. Separate strength sessions from your hardest running days when schedules allow. Insert easier “cutback” weeks every 3-4 weeks, reducing volume by 20-30%.
Tracking Progress and Staying Healthy
Improving running economy is a long-term process. Gains should not come at the cost of health or enjoyment.
Monitor improvements through simple markers:
- Stable or faster paces at the same perceived effort
- Lower heart rate at familiar speeds
- Less fatigue after routine runs
- Ability to maintain proper form later into long efforts
Recovery enables adaptation. Prioritize sleep, adequate nutrition, and strategic rest days. Watch for warning signs of overreaching: persistent soreness lasting more than 48 hours, declining performance despite consistent training, or loss of motivation. Back off if these appear.
For individualized guidance—especially if you experience pain, recurring shin splints, or other issues—consider consulting qualified coaches or healthcare professionals.
Conclusion: Ask Better Questions, Run More Efficiently
Running economy is trainable. Better running economy comes from attention to form, consistent strength work, progressive aerobic volume, and thoughtful equipment choices. Sustainable gains emerge from modest, layered changes rather than dramatic overhauls or sudden training spikes.
Which element offers your biggest opportunity? Perhaps it’s adding running form drills twice weekly. Maybe you’ve never touched a barbell or experimented with your step rate. Consider what gap exists in your current training routine.
Ask yourself: how might you measure “feeling easier” at a given pace over the next few months? What would it mean to run the same times with less effort?
The goal is to run faster while keeping running enjoyable and sustainable—not just for one race, but for years of forward movement.
