Estimate calories and kilojoules burned cycling based on your body weight, riding pace and either time in the saddle or distance covered. Based on 2024 Adult Compendium of Physical Activities MET values.
Cycling calorie burn is estimated using MET values (Metabolic Equivalent of Task): calories = MET × body weight (kg) × time (hours). A harder pace, a heavier rider or a longer ride all burn more. A 70 kg rider at a solid fitness pace (8.0 MET, ~22.5 km/h) burns about 560 calories in an hour — roughly 24.9 calories per kilometre ridden.
| Metric | Value |

The calculator multiplies a MET value — how many times harder an activity is than resting — by your body weight and the time you spend riding. It also converts your pace and time into a distance, so you can see calories per kilometre as well as per hour.
These figures use a fitness-pace ride (8.0 MET, ~22.5 km/h) held for a full hour. Heavier riders burn more for the same ride because the formula scales directly with body weight.
| Body weight | MET | Calories (60 min) | Kilojoules |
|---|---|---|---|
| 50 kg | 8.0 | 400 kcal | 1,674 kJ |
| 60 kg | 8.0 | 480 kcal | 2,008 kJ |
| 70 kg | 8.0 | 560 kcal | 2,343 kJ |
| 80 kg | 8.0 | 640 kcal | 2,678 kJ |
| 90 kg | 8.0 | 720 kcal | 3,012 kJ |
| 100 kg | 8.0 | 800 kcal | 3,347 kJ |
Same rider, same 30 minutes — only the pace changes. Because faster pace also means MET climbs faster than speed does, calorie burn rises sharply as effort increases, and covers a lot more ground too.
| Pace | MET | Speed | Distance (30 min) | Calories |
|---|---|---|---|---|
| Leisure ride | 4.0 | 16 km/h | 8.0 km | 140 kcal |
| Casual commute | 6.8 | 19.3 km/h | 9.65 km | 238 kcal |
| Fitness ride | 8.0 | 22.5 km/h | 11.25 km | 280 kcal |
| Tempo ride | 10.0 | 25.7 km/h | 12.85 km | 350 kcal |
| Hard effort | 12.0 | 29 km/h | 14.5 km | 420 kcal |
| Race pace | 16.8 | 35.4 km/h | 17.7 km | 588 kcal |
MET-based figures assume steady effort on flat ground, so your actual burn will drift from the estimate in a few predictable ways. Climbing takes noticeably more power than the flat, so a hilly route burns more than a flat one at the same average speed. Wind resistance grows with speed, not in a straight line — pushing into a headwind, or simply riding fast, costs disproportionately more energy than the calculator's flat-pace MET value assumes. Riding in a group and sitting in another rider's draft cuts that wind cost substantially, which is part of why bunch rides feel easier than the same speed solo. Surface (gravel versus smooth road), tyre pressure and bike weight all nudge the number slightly too. Treat the calculator's result as a solid planning estimate, not a lab measurement.
Australian food labels display energy in kilojoules (kJ), not calories, with a daily reference value of 8,700 kJ. To compare a ride against food labels, convert with: calories × 4.184 = kJ. Using the worked example above, a 70 kg rider's 60-minute fitness-pace ride burns 560 kcal, which is 560 × 4.184 = 2,343 kJ — a useful figure if you're weighing up a ride against a packaged snack or a meal's energy panel.
How many calories does a 30-minute bike ride burn?
It depends heavily on pace. For a 70 kg rider over 30 minutes: leisure pace burns about 140 kcal, casual commuting pace about 238 kcal, a fitness ride about 280 kcal, tempo about 350 kcal, hard effort about 420 kcal, and race pace about 588 kcal. Body weight shifts these figures up or down proportionally.
Does cycling burn more calories than running?
Minute for minute at a comparable effort level, running usually has a slightly higher MET value than cycling and can burn a bit more. But cycling lets most people sustain a faster pace for longer with far less joint impact, so over a full session the totals often end up similar or cycling can even win out, especially at tempo pace and above. The honest answer is both are effective — pick whichever you can sustain consistently.
How many calories does cycling burn per km?
At a fitness pace (8.0 MET, 22.5 km/h) a 70 kg rider burns about 24.9 kcal per kilometre. This figure isn't fixed — it depends on pace, because calories per km = MET × weight ÷ speed. A gentle leisure pace works out to roughly 17.5 kcal/km for a 70 kg rider, while race pace climbs to around 33 kcal/km, since harder efforts burn calories faster than the extra speed offsets.
How accurate is this calorie calculator?
It uses standardised MET values from the Compendium of Physical Activities, which are averages drawn from research on riders of varying fitness and technique. Your own metabolism, bike fit, cadence and conditions can shift the true number by roughly 10–20% in either direction. Treat the result as a solid estimate for planning, not a precise lab measurement.
Does riding uphill burn more calories than the calculator shows?
Yes, generally. The MET values here assume a steady effort on flat ground at the stated speed. Climbing demands more power for the same speed, so a hilly ride typically burns more than the flat-pace estimate suggests — even if your average speed looks similar once the descents are factored in. If most of your ride is uphill, consider selecting a harder pace preset to better reflect the effort.
Does riding in a group or drafting change how many calories I burn?
Yes. Sitting in another rider's slipstream reduces the wind resistance you have to push through, which lowers the effort needed to hold the same speed compared with riding solo into open air. This is why bunch rides can feel noticeably easier than a solo effort at the same speed — the calculator's MET values assume typical, not drafted, riding.
What pace should I pick if I don't know my average speed?
Match it to how the ride feels. A relaxed, conversational spin is close to leisure pace; a steady commute where you can still chat in short bursts sits around casual commute pace; a ride where you're working but can hold it for an hour is a fitness or tempo pace; and an effort you can only sustain for a shorter, harder session is hard effort or race pace. You can also switch to distance mode and let your GPS-tracked average speed pick the closest preset for you.
How many calories would I burn hitting the recommended weekly exercise target by cycling?
Australia's physical activity guidelines suggest 150–300 minutes of moderate activity, or 75–150 minutes of vigorous activity, each week. At a fitness pace (8.0 MET), a 70 kg rider covering the lower bound of 150 minutes (2.5 hours) burns about 8.0 × 70 × 2.5 = 1,400 kcal across the week from cycling alone — before counting any other activity.
