Running Efficiency Metrics: Measure Your Running Economy
Master stride efficiency and oxygen efficiency to run faster with less effort
Key Takeaways: Running Efficiency
- Running efficiency metrics combine stride count and time to measure your running economy
- Lower efficiency scores are better – like golf, the goal is to minimize your number
- Elite runners score 30-35 for 25m, while beginners score 60+
- Track your own progress – height and stride length make athlete comparisons invalid
- Improvement takes 6-12 weeks of consistent technique work to see meaningful gains
What is Running Efficiency?
Running efficiency measures how economically you move through space. The efficiency score combines your stride count and time into a single metric that reflects your running economy – the energy cost of maintaining a given pace.
Understanding running efficiency metrics helps you identify technique breakdowns, monitor fatigue, and optimize your stride mechanics for better performance. Research shows that improving running economy by just 5% can lead to significantly faster race times at the same effort level.
Running Efficiency Formula
Example Calculation: If you run 25 meters in 20 seconds taking 15 strides:
This represents elite-level stride efficiency and oxygen efficiency working together.
Why This Metric Matters for Running Economy
The efficiency score serves as a practical proxy for running economy – the amount of oxygen you consume at a given pace. Runners with better economy can maintain faster paces with less effort, leading to improved performance in races from 800m to marathons.
By tracking your efficiency score over time, you're monitoring improvements in stride efficiency, biomechanics, and overall running economy.
Normalized Running Efficiency for Distance Comparison
To compare scores across different measured distances:
Example: If you run 50m in 42 seconds with 32 strides:
Normalized to 25m = (42 × 25/50) + (32 × 25/50) = 21 + 16 = 37 points

What Your Score Means
Efficiency Score Components:
- Stride Count reflects your stride length and turnover rate
- Time reflects your absolute speed over the distance
- Combined Score reveals your overall stride efficiency
⚠️ Height and Body Type Matter
Taller runners naturally take fewer strides per distance, giving them lower efficiency scores. A 6'2" runner and a 5'6" runner at the same fitness level will have different scores due to stride length differences.
Solution: Use efficiency scores to track YOUR improvement over time, not to compare with other runners.
Expected Improvement Timeline
| Time Period | Expected Improvement |
|---|---|
| 4-6 weeks | 2-4 points reduction |
| 8-12 weeks | 5-8 points reduction |
| 6+ months | 10-15 points reduction |
Based on consistent technique work 2-3x per week
How to Improve Your Running Efficiency Score
Improving your efficiency score requires focused work on stride mechanics, running economy, and biomechanical efficiency. Here's a systematic approach to reduce your score and run more economically.
1. Optimize Stride Length and Cadence
The key to better stride efficiency is finding your optimal balance between stride length and turnover rate.
- Increase stride length through improved hip extension and stronger push-off
- Maintain 170-180 steps/minute cadence for optimal oxygen efficiency
- Avoid overstriding – landing with your foot ahead of your center of mass wastes energy
- Practice quick ground contact – elite runners spend less than 100ms on the ground per step
2. Improve Running Economy Through Strength
Research shows that running economy improves 3-8% with targeted strength training, directly reducing your efficiency score.
- Plyometric exercises – box jumps, bounding, single-leg hops improve reactive strength
- Core stability work – planks, anti-rotation exercises reduce energy leaks
- Calf strengthening – single-leg calf raises build powerful push-off
- Hip strength – glute bridges and clamshells improve stride mechanics
3. Enhance Oxygen Efficiency
Better oxygen efficiency means lower heart rate and perceived effort at the same pace – a key component of running economy.
- Build aerobic base – 80% of training at easy, conversational pace
- Include tempo runs – sustained efforts at lactate threshold improve economy
- Practice breathing patterns – 3:3 or 2:2 inhale:exhale rhythm reduces oxygen cost
- Improve VO₂max – interval training increases maximum oxygen uptake capacity
4. Refine Running Form and Biomechanics
Small form adjustments compound to significant efficiency improvements over time.
- Forward lean from ankles – use gravity to assist forward motion
- Relaxed upper body – tension in shoulders and arms wastes energy
- Mid-foot landing – reduces braking forces and improves efficiency
- Arm swing – keep elbows at 90°, hands swinging from hip to chest level
- Proper breathing – belly breathing vs. chest breathing improves oxygen exchange
5. Monitor Fatigue and Recovery
Fatigue degrades efficiency. Smart training preserves running economy while building fitness.
- Track efficiency trends – rising scores during workouts signal fatigue
- Implement recovery runs – easy days allow adaptation without accumulating fatigue
- Adequate sleep – 7-9 hours per night optimizes hormonal recovery
- Nutrition timing – proper fueling prevents technique breakdown in long runs
🎯 12-Week Efficiency Improvement Plan
- Weeks 1-4: Establish baseline – measure efficiency weekly, focus on cadence work
- Weeks 5-8: Add strength/plyometrics 2x/week + form drills before easy runs
- Weeks 9-12: Include weekly tempo run, maintain strength work, re-test efficiency
Expected outcome: 5-8 point reduction in efficiency score with consistent execution.
Understanding Running Economy Science
Running economy is defined as the energy cost (oxygen consumption) required to maintain a given running velocity. It's one of the three key physiological determinants of distance running performance, alongside VO₂max and lactate threshold.
🔬 Research on Running Economy
Costill et al. (1985) established that running economy is more important than VO₂max for middle-distance performance. Two runners with the same VO₂max can have 20-30% differences in running economy, directly affecting race performance.
Barnes & Kilding (2015) reviewed 60+ studies and found the key factors influencing running economy:
- Biomechanical efficiency (stride mechanics)
- Metabolic efficiency (oxygen utilization)
- Neuromuscular characteristics (muscle fiber type, stiffness)
- Anthropometric factors (body mass, limb proportions)
Saunders et al. (2004) showed that elite distance runners have 5-10% better running economy than good club-level runners at the same VO₂max – this economy difference explains much of the performance gap.
How Efficiency Score Relates to Running Economy
The efficiency score serves as a field-measurable proxy for running economy because:
- Lower stride count at a given pace indicates better biomechanical efficiency
- Faster time for the same stride count shows improved power output
- Combined score reduction correlates with reduced oxygen cost per meter
While laboratory running economy requires expensive gas analysis equipment, the efficiency score provides actionable feedback you can measure on any track or measured segment.
Interpreting Your Running Efficiency Patterns
📉 Decreasing Score = Improving Efficiency
When your efficiency score drops over weeks or months, your technique is improving or you're becoming more economical at a given pace. This is the goal of consistent training.
What's happening: Better stride mechanics, improved running economy, increased strength, or enhanced neuromuscular coordination.
📈 Increasing Score = Declining Efficiency
Rising efficiency scores during a workout signal fatigue causing technique breakdown, or running faster than your efficiency supports.
What's happening: Muscle fatigue, technique deterioration, inadequate recovery, or running above sustainable pace.
📊 Same Score, Different Components
An efficiency score of 45 could result from multiple stride/time combinations, revealing different running strategies:
- 20 seconds + 25 strides = High cadence, shorter stride length (common in beginners)
- 25 seconds + 20 strides = Lower cadence, longer stride length (typical of taller runners)
- 22.5 seconds + 22.5 strides = Balanced approach (ideal for most runners)
Analysis tip: Always examine stride count AND time separately to understand your specific efficiency profile and identify improvement opportunities.
🎯 Training Applications for Running Efficiency Metrics
- Technique Sessions: Aim to reduce efficiency score through form drills, strides, and conscious biomechanical focus
- Fatigue Monitoring: Rising efficiency during workouts indicates technique breakdown – time for recovery
- Pace-Efficiency Balance: Find the fastest pace you can hold without efficiency score spiking > 5 points
- Drill Effectiveness: Measure efficiency before/after drill sets to quantify technique transfer to actual running
- Race Pacing: Practice holding target race pace while maintaining consistent efficiency throughout the distance
Measurement Best Practices
📏 Counting Strides Accurately
- Count every foot strike (right + left = 2 strides)
- OR count right foot only and multiply by 2
- Use a measured track or GPS segment for consistent distance
- Start counting from your first step after beginning
- Count continuously until reaching the distance marker
- Practice counting during warm-up to build the skill
⏱️ Timing Your Runs
- Use a GPS watch for automatic lap timing (Garmin, Apple Watch, Coros, Polar)
- Or use manual split timing with track markers
- Maintain consistent effort across measured segments
- Record time to the nearest second
- Some advanced watches calculate stride metrics automatically
🔄 Ensuring Consistent Comparisons
- Same distance: Always use 25m, 50m, 100m, or full lap measurements
- Similar pace: Compare efficiency at your easy pace vs. tempo pace separately
- Fresh vs. fatigued: Note if measurement is from warm-up or mid-workout
- Track surface: Track, road, treadmill efficiency may differ slightly
- Weekly tracking: Measure efficiency during the same workout each week for trends
📊 Recording and Analyzing Data
Create a simple tracking spreadsheet or use a running app:
- Date, distance, time, stride count, efficiency score
- Note pace (min/km or min/mile)
- Add comments about fatigue, weather, or technique focus
- Calculate weekly average efficiency
- Graph trends over 4-week blocks
Running Efficiency Limitations and Considerations
🚫 Cannot Compare Between Athletes
Height, leg length, and biomechanical factors create natural stride count differences. A 6'2" runner will have a lower efficiency score than a 5'6" runner at identical fitness levels due to longer stride length.
Solution: Use efficiency scores for personal progress tracking only. Compare your score this month vs. last month, not against other runners.
🚫 Composite Score Masks Component Changes
The efficiency score combines two variables. You can improve stride length while slowing slightly (or vice versa) and maintain the same score, despite technique changes.
Solution: Always analyze stride count AND time separately. Look for patterns like "stride count down 3, time down 2" to understand true improvement.
🚫 Not Pace-Normalized
Efficiency scores naturally increase as you run faster – more strides per second equals higher combined numbers. This doesn't mean inefficiency, it's biomechanical reality.
Solution: Track efficiency at specific, repeatable paces. Create separate baselines for "efficiency at easy pace" (5:30/km) vs. "efficiency at tempo pace" (4:15/km).
🚫 Environmental and Fatigue Factors
Wind, temperature, hydration status, cumulative training fatigue, and time of day all affect efficiency scores independent of technique changes.
Solution: Measure efficiency during similar conditions (time of day, weather, fatigue state) for valid comparisons. Track trends over 4+ weeks to smooth out daily variation.
Running Efficiency Training Workouts
These workouts specifically target improvements in stride efficiency and running economy:
🎯 Efficiency Optimization Set
8 × 200m (90 seconds recovery jog)
- Reps #1-2: Run at comfortable pace, record baseline efficiency score and components
- Reps #3-4: Reduce stride count by 5-10, maintain same time → Focus on stride length extension
- Reps #5-6: Increase cadence +5-10 steps/min, keep similar stride count → Focus on turnover
- Reps #7-8: Find optimal balance that produces lowest efficiency score
Goal: Discover your most efficient stride count/cadence combination and practice holding it.
⚡ Efficiency Stability Test
6 × 800m @ Tempo Pace (2 minutes recovery)
Record efficiency score for each 800m (or each 200m within). Analyze:
- Which 800m had lowest efficiency? (Most economical running)
- Where did efficiency spike? (Technique breakdown or fatigue onset)
- How much did efficiency drift from first to last 800m?
Goal: Maintain efficiency within ±3 points across all reps. Consistency indicates strong technique under fatigue.
🏃 Form-Focused Efficiency Intervals
10 × 400m (200m jog recovery)
Alternate focus each rep:
- Odd reps: Focus on quick ground contact ("hot coals") – minimize foot contact time
- Even reps: Focus on powerful push-off – drive from glutes, extend hips fully
Record efficiency for each rep and compare focus types.
Goal: Identify which technical cue produces better efficiency for YOUR biomechanics.
💪 Strength-to-Efficiency Connector
Pre-run activation + efficiency test
- 5 minutes easy running warm-up
- Activation circuit: 3 rounds of:
- 10 single-leg calf raises per leg
- 10 glute bridges
- 30-second plank
- 5-minute easy running
- 4 × 200m measuring efficiency score
Goal: Compare efficiency with vs. without pre-activation. Many runners see 2-4 point improvement after activation.
Frequently Asked Questions
What are running efficiency metrics?
Running efficiency metrics measure how economically you move. The efficiency score combines your stride count and time over a set distance into a single number. Like golf, lower scores are better. The score reflects both stride efficiency (biomechanics) and oxygen efficiency (aerobic capacity). For example: 20 seconds + 15 strides = efficiency score of 35.
How do I calculate my running efficiency score?
Run a measured distance (25m, 50m, 100m, or 400m lap), count every stride (foot strike), and record your time in seconds. Add stride count to time in seconds. Example: 100m in 75 seconds with 95 strides = efficiency score of 170. Many GPS watches with stride sensors calculate this automatically.
What is a good running efficiency score?
For 25m distance: Elite runners score 30-35, competitive runners 35-45, fitness runners 45-60, beginners 60+. Your height significantly affects stride count – taller runners naturally score lower. Focus on improving YOUR score over time (aim for 5-8 point reduction in 8-12 weeks) rather than comparing with others.
Can I compare my running efficiency with other runners?
No. Efficiency scores are highly individual due to height, leg length, and biomechanical differences. A 6'2" runner with poor technique might score the same as a 5'6" runner with excellent technique. Use efficiency metrics to track your own progress over weeks and months, not to compare with training partners or competitors.
What is running economy and how does it relate to efficiency?
Running economy is the oxygen cost of maintaining a given pace. It's a key predictor of race performance. Better running economy means you consume less oxygen at the same speed. The efficiency score serves as a field test proxy for running economy – as your score improves (decreases), your running economy typically improves, meaning you're running more efficiently at the same perceived effort.
Should my running efficiency score go up or down as I run faster?
Efficiency scores naturally increase slightly at faster paces due to biomechanics – you need more strides per second and the numbers compound. This is normal physics, not inefficiency. Track efficiency at consistent, specific paces separately: "efficiency at easy pace (5:30/km)" vs. "efficiency at tempo pace (4:15/km)." Improvement means the score decreases over time at that same pace.
Why is my running efficiency getting worse during workouts?
Increasing efficiency score during a workout indicates fatigue causing technique breakdown. This is normal and reveals where your form deteriorates under stress. If efficiency rises 5+ points during a workout, that's your technique failure point. Use this information to identify technical weaknesses and build endurance at those specific paces with shorter intervals and more recovery.
How long does it take to improve running efficiency?
With consistent technique work 2-3x per week: expect 2-4 point improvement in 4-6 weeks, 5-8 points in 8-12 weeks, and 10-15 points in 6+ months. Improvements come from strength training (especially plyometrics), form drills, cadence optimization, and building aerobic base. Quick wins include cadence work (try running at 180 steps/minute) which can improve scores 3-5 points in one month.
What is stride efficiency in running?
Stride efficiency refers to how effectively you convert each stride into forward motion with minimal wasted energy. It's influenced by stride length, ground contact time, vertical oscillation, and biomechanical alignment. Good stride efficiency means covering maximum distance per stride with optimal energy cost. The stride component of the efficiency score directly reflects your stride efficiency.
What is oxygen efficiency in running?
Oxygen efficiency (part of running economy) refers to how much oxygen you consume to maintain a given pace. Better oxygen efficiency means lower heart rate and breathing rate at the same speed. Improve it through aerobic base building (easy runs), tempo runs at lactate threshold, VO₂max intervals, and proper breathing mechanics. The time component of the efficiency score reflects your aerobic capacity and oxygen efficiency.
How can I improve my running efficiency?
Five key strategies: (1) Optimize cadence to 170-180 steps/minute, (2) Add plyometric and strength training twice weekly, (3) Practice running form drills focusing on quick ground contact and forward lean, (4) Build aerobic base with 80% of miles at easy pace, (5) Include weekly tempo runs at lactate threshold. Consistency over 8-12 weeks yields measurable improvements. See our detailed improvement section above for specific workouts and drills.
