Bike Pace Calculator
Enter any two of distance, ride time, and speed and this calculator instantly solves for the missing value. You also get your pace in minutes per kilometre (or per mile), an estimate of calories burned, and a split-pace chart so you can see how changes in effort change your total time. Switch between metric and imperial units with one click.
How the bike pace calculator works
This calculator solves the fundamental cycling equation - Speed = Distance / Time - in any direction. Choose what you want to find out: select "Speed" and enter your distance and ride time; select "Time" and enter distance and target speed; or select "Distance" to find how far you will travel at a given speed in a set time. Your pace (minutes per kilometre or per mile) is derived automatically from whichever two values are known, because pace = 60 / speed. The calorie estimate uses a MET (Metabolic Equivalent of Task) model scaled by your rider weight and blended with a distance-based coefficient for the speed you have entered.
Speed, pace, and the three-way cycling equation
Speed, time, and distance are three sides of the same triangle. Knowing any two gives you the third. Speed = Distance / Time. Time = Distance / Speed. Distance = Speed x Time. Pace is just speed expressed from the other direction: instead of kilometres per hour, you track minutes per kilometre. A speed of 25 km/h equals a pace of 2:24 min/km (60 / 25 = 2.4 minutes = 2 min 24 sec). Pace is especially useful for structured training because it is easier to hold a minute-per-km target on a watch than to maintain an exact speed readout. Both numbers reflect the same underlying relationship, so switching between them requires nothing more than division.
Factors that affect your average cycling speed
Your average speed over a real-world ride is shaped by terrain (flat roads are fastest, every 100 m of elevation gain adds roughly 3-5 minutes per hour of climbing time), wind (a 20 km/h headwind can cut 5-10 km/h from your average), surface type (gravel and unpaved roads reduce speed by 10-20% compared to tarmac), bike fit and position (an aggressive aero tuck saves significant drag at speeds above 30 km/h), equipment (road bike vs. mountain bike vs. hybrid), and fatigue over longer distances. The averages in the reference table assume flat, paved roads with no significant wind.
Calorie burn while cycling
Energy expenditure on a bike depends on speed, body weight, terrain, drafting, and equipment efficiency. As a practical rule, a 75 kg rider burns roughly 25-50 kcal per kilometre depending on effort level: about 25 kcal/km at an easy 12-15 km/h, rising to 50 kcal/km at a racing pace above 35 km/h. The MET model used here multiplies your weight in kilograms by your ride time in hours by a metabolic factor (6 for easy riding, up to 12 for hard racing). This estimate is a useful planning guide but can vary 20-30% based on individual physiology, terrain, and conditions.
Average cycling speed by experience level
| Level | Speed (km/h) | Speed (mph) | Pace (min/km) | Pace (min/mi) |
|---|---|---|---|---|
| Beginner | 12-16 | 7.5-10 | 3:45-5:00 | 6:00-8:00 |
| Recreational | 16-22 | 10-14 | 2:44-3:45 | 4:17-6:00 |
| Intermediate | 23-30 | 14-19 | 2:00-2:37 | 3:09-4:17 |
| Advanced | 31-38 | 19-24 | 1:35-1:56 | 2:30-3:09 |
| Elite / Pro | 39+ | 24+ | below 1:32 | below 2:30 |

Frequently asked questions
What is a good average speed for cycling?
It depends on your experience and the terrain. On flat roads, beginners typically average 12 to 16 km/h (7-10 mph), recreational cyclists manage 16 to 22 km/h (10-14 mph), intermediate riders cruise at 23 to 30 km/h (14-19 mph), and advanced cyclists sustain 31 km/h or more (19+ mph). Serious club riders and professionals regularly average 38 to 45 km/h (24-28 mph) in racing conditions.
What is the difference between speed and pace in cycling?
Speed is distance per unit time (km/h or mph). Pace flips that relationship to time per unit distance (min/km or min/mi). They convey the same information in different formats. Pace is common in running and triathlon training because it is easier to monitor on a watch. To convert speed to pace: divide 60 by your speed in km/h to get min/km. For example, 30 km/h becomes 60/30 = 2:00 min/km.
How do I calculate how long it will take to ride a specific distance?
Use the formula Time = Distance / Speed. For example, riding 60 km at an average speed of 25 km/h will take 60 / 25 = 2.4 hours, or 2 hours 24 minutes. Select "Time" from the "Solve for" dropdown in this calculator, enter your distance and expected speed, and the result updates instantly.
How many calories do you burn cycling?
A 75 kg rider burns roughly 400-600 kcal per hour at a recreational pace (16-22 km/h), rising to 700-1000 kcal/h at an advanced pace (30+ km/h). The key variables are body weight (heavier riders burn more), speed (harder efforts burn more per hour), ride duration, and terrain. This calculator uses a MET-based model blended with a distance coefficient to estimate your calories for the specific ride you have entered.
How does terrain affect cycling speed?
Flat, smooth tarmac produces the fastest average speeds. Rolling hills reduce average speed by 2-5 km/h depending on the gradient and your fitness. Mountainous routes can cut speed by 8-15 km/h. Gravel and unpaved surfaces reduce speed by 10-20% compared to paved roads due to increased rolling resistance. Headwinds have a similar penalty to climbing: a 20 km/h headwind can add as much time to a ride as a steady moderate gradient.
What is a realistic average speed for a 100 km ride?
For a recreational cyclist on flat terrain, 20-25 km/h is realistic, meaning a 100 km ride takes 4-5 hours of moving time. Intermediate riders might average 25-30 km/h (3:20-4:00 total). Advanced club riders can sustain 30-35 km/h (2:52-3:20). Add 15-30 minutes of total time for stops, food, and traffic. Hilly courses or adverse conditions will slow these figures considerably.
