When researchers measured the calorie cost of covering one mile, walkers and runners burned nearly the same amount.
The per-mile burn landed between 93-99 kcal regardless of whether subjects walked or ran. The gap between walking 5km vs running 5km is far smaller than most people assume.
So which one should you actually choose? That depends on your goals, your body, and how much time you have.
We compared the science on calories, weight loss, heart health, injury risk, and mental benefits so you can make the right call.
Key Takeaways:
- Mile-for-mile, walking and running burn surprisingly similar calories (only 10-30% difference per mile), though running finishes faster and triggers a greater afterburn effect.
- For heart health, both activities reduce cardiovascular risk equally when you cover the same distance.
- Running carries 2-3x the injury risk of walking due to high impact forces, making walking the safer long-term choice for beginners and those with joint concerns.
- The best exercise for weight loss is the one you actually stick with. Walking has near-zero dropout rates, while running often triggers compensatory hunger.
Walking vs Running 5km at a Glance
Here is a side-by-side snapshot of how the two compare across the metrics that matter most.
| Factor | Walking 5km | Running 5km |
|---|---|---|
| Time | 45-60 minutes | 25-35 minutes |
| Calories burned | 200-300 kcal | 300-500 kcal |
| Calories per mile | ~93-99 kcal | ~93-99 kcal |
| EPOC (afterburn) | Minimal (10 min) | Moderate, 6-15% extra (15 min) |
| MET value | 3-6 (moderate) | 6+ (vigorous) |
| Injury rate | Very low | 7.7-17.8 per 1,000 hrs |
| Cardiovascular benefit | Strong at equivalent distance | Strong, faster VO2 max gains |
| Equipment needed | Comfortable shoes | Running shoes |
| Accessibility | Almost anyone, any fitness level | Requires baseline fitness |
The time difference is the big trade-off. Running covers 5km in roughly half the time, so it burns more calories per minute. But when you compare the same distance, the calorie gap narrows dramatically.
Notice that the per-mile calorie burn is virtually identical. That is the single most important row in this table. Your choice depends on which resource matters more to you: time or sustainability.
If you have 30 minutes and want maximum output, run. If you want something you can do every single day without recovery concerns, walk.
Walking requires no special gear, no warm-up ritual, and no fitness base. You can start today, at any age, at any weight.
One more thing worth noticing: the MET values. Walking registers at 3-6 METs (moderate intensity), while running sits at 6+ METs (vigorous).
That gap matters for how hard your cardiovascular system works per minute. But hiking uphill or taking stairs can push walking METs into running territory without the joint impact.
1. Calorie Burn and the Afterburn Effect

You would think running would obliterate walking in a calorie comparison. The numbers tell a more nuanced story.
Wilkin et al. (2012) measured energy expenditure for 1,600 meters in both walkers and runners. Running burned 471 kJ during exercise versus 373 kJ for walking. That is a 26% advantage for running over the same distance.
The story does not end when you stop moving. EPOC (excess post-exercise oxygen consumption) is the extra calorie burn your body generates during recovery.
Your body continues consuming oxygen at an elevated rate as it restores itself to baseline. Running produced total energy expenditure of 664 kJ versus 463 kJ for walking when EPOC was included.
According to Cleveland Clinic, EPOC can add 6-15% on top of your workout calories, and it lasts longer after higher-intensity efforts.
Exercise physiologist Alex Harrison, PhD, points out that the mile-for-mile calorie difference between walking and running is only 10-30%. That is much smaller than most fitness apps would have you believe.
Per-minute comparisons paint a different picture. A 160-pound person burns roughly 15.1 calories per minute running versus 8.7 walking.
That makes running look dominant. But per-minute stats are misleading if you are covering the same distance regardless of speed.
For a 70kg person doing 5km, expect roughly 300-350 calories from running in about 30 minutes and 200-270 from walking in about 55 minutes. The gap exists, but it is not the 2x blowout many people expect.
Your body weight plays a bigger role than your speed. Calorie burn stays relatively steady regardless of pace by distance,
Greater muscle forces are needed to move faster, but the total cost per kilometer evens out. A heavier person walking 5km may burn more total calories than a lighter person running the same distance.
2. Weight Loss: Which Gets Results Faster?
If you have ever started a running program to lose weight and quit within three weeks, you are not alone.
The most effective weight loss exercise is not the one that burns the most calories. It is the one you keep doing.
Data from the National Runners’ and Walkers’ Health Studies found that running-related calorie expenditure led to 90% more weight loss than equivalent walking calories over six years.
On paper, running wins. But that study tracked people who stuck with both activities long-term.
In practice, running has a compliance problem. Running depletes glycogen stores, which triggers hunger and cravings.
High-intensity exercise creates compensatory appetite, meaning runners often eat back the extra calories they burned. Walking produces far less appetite stimulation, which makes the calorie deficit easier to maintain.
Walking also has near-zero dropout rates. Almost anyone can walk 5km daily without needing rest days, special gear, or a gradual ramp-up.
Running demands recovery time, progressive overload planning, and often causes enough soreness or injury to force breaks. Once sidelined, the habit breaks, and most people never restart.
There is a practical advantage to walking that rarely gets mentioned. You can walk 5km on a full stomach, in work clothes, during a lunch break, or while taking a phone call.
You can split it into two 2.5km walks, morning and evening. Running demands preparation, dedicated gear, and recovery time. That friction quietly kills consistency.
Best for: Beginners, anyone who has tried running programs and quit, people who want steady fat loss without hunger spikes.
Skip if: You are already a consistent runner who enjoys the intensity and can manage appetite. In that case, running’s higher per-session burn gives you an edge.
The bottom line for weight loss is simple. Five kilometers walked every day beats five kilometers run three times a week (then abandoned by month two).
3. Heart Health and Cardiovascular Fitness

Both walking and running are outstanding for your heart. The research on just how equal they are may surprise you.
Lee et al. (2014) followed 55,137 adults and found that runners had a 45-50% reduced risk of cardiovascular death compared to non-runners.
Even running at slow speeds for as little as 5-10 minutes per day produced significant benefits. Runners also gained roughly 3 years of life expectancy.
Walking is no slouch. The National Runners’ and Walkers’ Health Studies compared 32,000 runners with 15,000 walkers over six years.
When the two groups burned equivalent calories through their respective activities, they saw equal reductions in blood pressure, cholesterol, and diabetes risk. That is 47,000+ participants confirming the same finding: equal distance, equal protection.
This is a powerful result for anyone who cannot or prefers not to run. A 5km walk provides roughly the same heart protection as a 5km run, as long as you cover those kilometers consistently.
For people already managing high blood pressure, walking may be the smarter choice because it places less acute cardiovascular stress on the body.
You get the long-term protective effects without pushing your cardiovascular system into zones that feel risky or uncomfortable.
Where running does pull ahead is in VO2 max improvement. Running pushes your heart rate into higher zones more consistently, which drives faster aerobic adaptations.
If improving cardiovascular fitness is your primary goal (not just reducing disease risk), running gets you there sooner.
The verdict: For disease prevention, walking 5km and running 5km offer comparable benefits. For athletic cardiovascular performance, running has the edge. Either way, covering the distance matters more than the speed you cover it at.
4. Injury Risk and Joint Impact
Every runner knows the frustration: you build momentum, start seeing results, then a knee or shin issue sidelines you for weeks. Injury is running’s biggest hidden cost.
Videbæk et al. (2015) conducted a meta-analysis of 13 prospective studies and found injury rates of 17.8 per 1,000 hours for novice runners and 7.7 per 1,000 hours for recreational runners.
Annual injury rates for recreational runners range from 37% to 56%. Roughly half of all runners get hurt every year.
The physics explain why. Each running foot strike generates force equal to 2-3 times your body weight. Over a 5km run, that adds up to thousands of high-force impacts on your joints.
Walking always keeps at least one foot on the ground, eliminating the flight phase that creates those jarring loads.
The most common running injuries include runner’s knee, shin splints, Achilles tendinitis, and plantar fasciitis. These are overuse injuries that develop gradually and can take weeks or months to heal.
There is one important counterpoint. Running stimulates bone density more effectively than walking due to those same impact forces.
For people at risk of osteoporosis (especially postmenopausal women), the mechanical loading from running can be protective. Weight-bearing impact is not inherently bad. It is a question of dosage.
Walking injuries are rare enough that most studies do not even track them. You can walk 5km every day of the week without worrying about shin splints, IT band syndrome, or plantar fasciitis. That reliability is walking’s greatest advantage for long-term health.
Our recommendation: If you are a beginner, have a BMI over 30, are over 50, or have a history of joint problems, start with walking.
You get the cardiovascular and metabolic benefits with a fraction of the injury risk. If you are injury-free and want to run, build up gradually (no more than 10% weekly mileage increase) and include rest days.
5. Mental Health and Cognitive Benefits

A 2014 Stanford study found that walking boosts creative thinking by 60%. That finding alone should change how you think about your daily stroll.
Running gets most of the mental health attention thanks to the “runner’s high,” that endorphin-driven euphoria that kicks in during sustained effort.
It is real, well-documented, and genuinely effective for mood regulation and anxiety relief.
Walking delivers its own cognitive advantages that running cannot easily replicate. Walking activates the parasympathetic nervous system, shifting your body into rest-and-heal mode and lowering cortisol.
That makes it ideal for daily stress management, problem-solving, and creative work.
Walking outdoors amplifies these effects. Additional mental health benefits from nature exposure beyond what indoor exercise provides.
Post-meal walking deserves a special mention. A 15-minute walk after eating helps blunt blood sugar spikes, improving insulin sensitivity and energy levels throughout the day.
This benefit is unique to lower-intensity movement and does not require running-level effort.
Running works best as a mental health tool for people who need intense mood elevation or are managing clinical depression.
The endorphin response from vigorous exercise is stronger and faster-acting than what walking provides.
Both activities also improve sleep quality, one of the most underrated factors in mental health. Poor sleep worsens anxiety, depression, and cognitive performance in a vicious cycle.
Regular 5km sessions of either walking or running help regulate your circadian rhythm and deepen sleep cycles.
Best for walking: Daily stress relief, creative thinking, blood sugar management, meditative reflection.
Best for running: Endorphin-driven mood boosts, managing depression symptoms, building mental toughness.
FAQs
Is walking 5km a day enough exercise?
Yes. Walking 5km daily exceeds the WHO’s recommended 150 minutes of moderate activity per week. It burns 200-300 calories per session, supports heart health, and reduces all-cause mortality. For most adults, a daily 5km walk is more than enough to maintain good health.
How long does it take to walk 5km vs run 5km?
Most people walk 5km in 45-60 minutes at a brisk pace (about 5-6 km/h). Running 5km takes 25-35 minutes at a moderate jogging pace (8-12 km/h). Beginners should expect the longer end of both ranges.
Can I lose weight by walking 5km every day?
Yes. Walking 5km burns roughly 200-300 calories depending on your weight and pace. Over a week, that adds up to 1,400-2,100 calories, enough to lose about 0.2-0.3 kg per week without dietary changes. Combined with a modest calorie deficit, daily 5km walks produce consistent fat loss.
Is it better to walk 5km or run 2.5km?
Walking 5km burns more total calories than running 2.5km, despite running’s higher per-minute burn rate. Walking 5km also provides more cardiovascular benefit because you cover double the distance. If time allows, the longer walk wins on most health metrics.
The Bottom Line
There is no single winner here. The best choice depends entirely on who you are and what you need.
- Beginner or returning to fitness: Walk. Build the habit first, then add running intervals if you want.
- Short on time: Run. You will cover 5km in 25-35 minutes instead of 50-60.
- Primary goal is weight loss: Walk daily. Consistency and low appetite disruption beat raw calorie burn.
- Primary goal is heart health: Either works. Just cover the distance regularly.
- History of joint injuries: Walk. The reduced impact keeps you moving long-term.
- Already a runner who enjoys it: Keep running. Add walking on recovery days.
- Mental health focus: Walk for daily maintenance, run for acute mood elevation.
If you are torn between the two, consider a walk-to-run bridge approach. Start with 5km walks, then gradually introduce 1-minute running intervals every few minutes.
Over weeks, shift the ratio until you are running more than walking. This builds fitness while keeping injury risk low.
You do not have to pick one forever. Many experienced athletes mix both into their weekly routine.
Three walking days and two running days gives you the consistency of walking with the intensity benefits of running. Flexibility beats rigidity when it comes to lifelong fitness.
