How is cycling distance converted to running distance?

The conversion uses MET (Metabolic Equivalent of Task) values for each activity at the given speeds. The formula is: Running Distance = Cycling Distance × (MET_cycling / MET_running) × (Running Speed / Cycling Speed). This accounts for the metabolic load of each activity relative to the speeds involved. See also our Gear Ratio (Chainring 1 / Cog 1) — Bike Gear.

What is a MET value and why does it matter?

MET stands for Metabolic Equivalent of Task — it measures how much energy an activity burns relative to resting. A higher MET means more intense effort. By comparing the MET values of cycling and running at your chosen speeds, the calculator finds the running distance that demands the same metabolic effort as your bike ride.

Why does a typical 30 km bike ride not equal 30 km of running?

Cycling is mechanically more efficient than running due to the bike's drivetrain and the absence of repeated impact loading. At similar speeds, running burns significantly more energy per kilometre than cycling. As a rough rule of thumb, 1 km of running is roughly equivalent to 3 km of cycling at moderate intensity.

Does body weight affect the conversion?

Body weight directly affects calorie calculations, since heavier athletes burn more calories for the same activity. While the core distance conversion ratio is primarily driven by MET and speed ratios, body weight is used to estimate the total calories burned during the cycling workout.

Is this calculator useful for triathletes?

Absolutely. Triathletes regularly need to balance training load across swimming, cycling, and running. Converting your cycling kilometres to a running equivalent helps you gauge total workout stress, plan recovery, and avoid overtraining when substituting one discipline for another.

Can I use this calculator for stationary (indoor) cycling?

Yes. Enter your target cycling speed or the equivalent resistance level speed. Keep in mind that indoor cycling at a given speed may feel harder than outdoor cycling because there is no drafting benefit and resistance is manually set, so your actual MET may be slightly higher indoors.

What running speed should I enter for the most accurate result?

Enter the running speed that corresponds to a similar perceived effort or heart rate zone as your cycling workout. If you cycle at a moderate aerobic pace, use a moderate running pace (around 9–12 km/h for most recreational athletes). Matching intensity zones gives the most meaningful conversion.

How accurate is the MET-based conversion method?

MET-based conversions are a well-established scientific approach used in exercise physiology research. The accuracy depends on how closely your actual cycling and running speeds match the values you enter. Individual factors like fitness level, terrain, and equipment can cause small variations, but the result is a reliable training-load estimate.
