How does this running calorie burn calculator work?

It applies the standard activity equation: kcal ≈ MET × body weight (kg) × duration (hours). You pick a pace/effort band (each maps to a MET from compendium-style running speeds), enter weight and minutes, and get an estimate. Default on this page: 70 kg, 30 min, steady band (9.8 MET, ~6 mph) → ~343 kcal (~11.4 kcal/min). Same formula as our general calories burned calculator for consistent cross-activity numbers. kcal ≈ 9.8 MET × 70 kg × 0.50 h ≈ 343 kcal

What is a MET in running calorie estimates?

MET (metabolic equivalent of task) compares exercise intensity to quiet sitting (~1 MET). Running bands here span 6 MET (walk/very slow jog) to 14.5 MET (very hard). At 70 kg for 30 minutes: walk/jog ≈ 210 kcal, easy ≈ 291 kcal, steady ≈ 343 kcal, tempo ≈ 385 kcal, hard ≈ 431 kcal, very hard ≈ 508 kcal. Higher MET = more kcal per minute at the same weight.

How many calories does a 30-minute run burn?

Depends on weight and pace. This page’s default (70 kg, steady 9.8 MET): ~343 kcal in 30 min. Same weight, easy 45 min: ~374 kcal (8.3 MET). Walk/jog 20 min: ~140 kcal. Tempo 60 min at 80 kg: ~880 kcal. A heavier runner at the same band burns more—90 kg, hard 40 min: ~738 kcal.

How many calories per mile running?

At the steady band (~6 mph), one mile takes about 10 minutes. For 70 kg: kcal/mile ≈ 9.8 × 70 × (10÷60) ≈ 114 kcal/mile. Five miles at that effort (~50 min total): ~572 kcal in this model. Faster bands raise per-mile cost—very hard 25 min at 70 kg totals ~423 kcal (14.5 MET), not comparable to a full easy mile pace.

How many calories does a half marathon burn?

If you held the steady band for 90 minutes at 70 kg (planning estimate, not race-day variability): kcal ≈ 9.8 × 70 × 1.5 h ≈ 1029 kcal. Real races mix easy miles, surges, and walk breaks—use average effort or split mentally. A 4-hour marathon at the same steady MET and weight: ~2744 kcal over 240 min—most finishers run slower average MET than a 6 mph treadmill band.

Why is my GPS watch different from this estimate?

Watches blend heart rate, pace, and proprietary models; we use fixed MET tables. Your 343 kcal steady estimate might read ±10–25% on a wrist device. Use watches for week-to-week trends and MET math for quick “what-if” planning when you know weight and average pace band.

Do hills and wind change calorie burn?

Yes—grade and headwind raise energy cost beyond flat MET tables. This tool does not add incline %. If a hilly 30 min felt like tempo effort, pick tempo (11 MET → ~385 kcal at 70 kg/30 min) instead of steady (343 kcal). Trail runners often bump one band for the whole outing.

How should I log interval workouts?

Option A: weighted average—25 min with 15 min easy + 10 min hard might sit near easy/tempo blend (~140 kcal easy-only vs ~423 kcal for 25 min very hard). Option B: calculate each segment separately and add. Short sprints at 14.5 MET spike kcal/min but total time matters.

Is treadmill calorie burn the same as outdoor running?

Often similar at matched belt speed, but lack of wind, belt assist, and heat change perceived effort. If 30 min on the treadmill at “steady” pace feels easier than road, you might still log ~343 kcal at 70 kg—or choose easy (8.3 MET) if heart rate stays lower. Consistency matters more than perfect kcal.

Should I eat back every calorie I burn running?

Not automatically. A 30-min run (~343 kcal here) is only part of total daily energy. Use our TDEE or calorie calculator for weekly targets; add partial run fuel for long efforts (e.g. half-planning ~1029 kcal) based on hunger, performance, and clinician advice—not the full estimate every time.

Does body weight affect calories burned running?

Yes—kcal scales linearly with kg in MET × kg × hours. Steady 30 min: 60 kg → ~294 kcal, 70 kg → ~343 kcal, 80 kg → ~392 kcal. US units example: 154 lb (~70 kg), 60 min steady → ~685 kcal. Body composition and running economy still shift real expenditure around these averages.

Is this running calorie calculator medical advice?

No—education and training estimates only. Chest pain, eating disorders, diabetes, pregnancy, or return-to-run after injury need qualified healthcare and coaching—not MET tables alone.

Limitations

MET bands are population averages—your heart rate, running economy, and surface change true cost
Hills, wind, heat, and backpack load are not modeled—bump the pace band if the whole run was harder
Treadmill belt assist and outdoor drafting differ slightly from compendium paces at the same speed
Interval workouts need average effort across the session or split into segments mentally
Not medical nutrition advice—eating disorders, diabetes, or pregnancy need clinician guidance
