Cycling Speed Calculator
Calculate average cycling speed from distance and time, or estimate time and distance for a given speed.
Calculator
Formula
v = average speed (km/h or mph), d = distance (km or miles), t = time (hours). Speed equals distance divided by elapsed time. Time equals distance divided by speed. Distance equals speed multiplied by time.

How it works
Average cycling speed is calculated by dividing the total distance covered by the total elapsed time: v = d / t. Distance is entered in kilometres and time is broken into hours, minutes, and seconds to allow precise input of any ride duration. The calculator converts speed to miles per hour by dividing km/h by the factor 1.60934.
Pace (minutes per kilometre or per mile) is the reciprocal metric: total minutes divided by distance. Pace is useful for comparing effort across rides of different lengths and is widely used in training plans alongside speed. A lower pace number means you are moving faster.
The Metabolic Equivalent of Task (MET) estimate uses the compendium of physical activities thresholds published by Ainsworth et al. (2011): below 16 km/h is MET 6, 16–19.2 km/h is MET 8, 19.3–22.3 km/h is MET 10, 22.4–25.5 km/h is MET 12, and 25.6 km/h or above is MET 16. Multiply MET by your body weight in kg and by hours ridden to estimate kilocalories burned.
Worked example
Example: You ride 40 km in 1 hour 15 minutes 0 seconds.
Step 1 — Convert time to hours: 1 + 15/60 + 0/3600 = 1.25 hours.
Step 2 — Calculate speed: 40 ÷ 1.25 = 32.00 km/h.
Step 3 — Convert to mph: 32.00 ÷ 1.60934 = 19.88 mph.
Step 4 — Calculate pace: (1.25 × 60) ÷ 40 = 75 ÷ 40 = 1.875 min/km (i.e. 1 min 52.5 sec per km).
Step 5 — Estimate MET: 32 km/h falls in the 25.6+ bracket → MET = 16. For a 70 kg rider over 1.25 hours: 16 × 70 × 1.25 = 1,400 kcal estimated.
Limitations & notes
This calculator assumes a constant average speed over the entire ride. Real-world rides include acceleration, coasting, stops at traffic lights, and elevation changes that mean instantaneous speed varies considerably from the average. GPS-recorded moving time (excluding pauses) will yield a higher average speed than total elapsed time.
The MET estimates are broad brackets derived from laboratory measurements on level ground and do not account for wind resistance, gradient, rider position, equipment weight, or drafting. They should be treated as rough approximations rather than precise calorie counts. For clinical or medical purposes, consult a qualified exercise physiologist.
The conversion factor between kilometres and miles used here (1 mile = 1.60934 km) is the international standard and accurate to five decimal places.
Frequently asked questions
What is a good average cycling speed for a beginner?
Most beginners cycling on flat terrain average between 14 and 18 km/h (about 9–11 mph). As fitness improves over weeks of consistent riding, reaching 20–24 km/h becomes realistic on a road bike without significant hills or headwinds.
How does gradient affect average cycling speed?
Gradient has a dramatic effect. A 5% uphill grade can halve your speed compared to flat terrain at the same power output. Conversely, descents can push speeds well above 50 km/h. For hilly routes, expect your average speed to be 3–6 km/h lower than a comparable flat ride.
Should I use moving time or total elapsed time?
Using moving time (excluding stops) gives a higher average speed and is the standard used by most cycling apps and coaches when assessing performance. Total elapsed time is more useful for logistics — such as estimating when you will arrive at a destination — while moving time better reflects your actual riding effort.
What average speed do professional cyclists sustain in a race?
Professional road cyclists average 40–45 km/h (25–28 mph) over flat Tour de France stages. Time trialists can average above 50 km/h for an hour in world-record attempts. Olympic track cyclists hit burst speeds exceeding 70 km/h on the velodrome.
How can I improve my average cycling speed?
Key strategies include interval training (alternating hard efforts with recovery), improving aerodynamics by adopting a lower riding position, maintaining a higher cadence (90–100 rpm) for better efficiency, reducing total bike and body weight, and ensuring correct tyre pressure. Regular structured training over 8–12 weeks typically yields measurable speed gains.
How do I convert cycling speed to calories burned?
Use the MET (Metabolic Equivalent of Task) method: Calories = MET × body weight in kg × time in hours. For example, riding at 25 km/h (MET ≈ 12) for 1 hour at 70 kg burns approximately 12 × 70 × 1 = 840 kcal. This is an estimate; actual burn varies with fitness level, terrain, and equipment.
