Calculating Bike Speed
Average cycling speed is simply the distance covered divided by the time taken. This fundamental calculation helps you track fitness progress, plan routes, and set performance goals. While GPS devices provide real-time speed data, understanding the math behind speed calculations helps you plan rides and compare performances across different conditions.
It is important to distinguish between average speed (total distance / total time) and moving speed (total distance / moving time only, excluding stops). Most cycling computers report both, and the difference can be significant on rides with traffic lights, rest stops, or photo breaks.

Speed Levels
| Category | Speed (mph) | 20-Mile Time |
|---|---|---|
| Casual | 8-12 | 1:40-2:30 |
| Fitness | 13-16 | 1:15-1:32 |
| Experienced | 17-20 | 1:00-1:11 |
| Competitive | 21-25 | 0:48-0:57 |
| Elite | 26+ | Under 0:46 |
How to Ride Faster
- Improve your aerodynamic position -- lower handlebars and tucked elbows reduce drag significantly.
- Increase weekly mileage gradually to build endurance and aerobic capacity.
- Include interval training: 4-5 sets of 5-minute efforts at threshold intensity.
- Reduce rolling resistance with properly inflated tires and quality rubber compounds.
- Draft behind other riders in group rides to save 20-30% of your energy at the same speed.
Frequently Asked Questions
How fast can a beginner cyclist ride?
Most beginner cyclists average 10-14 mph on flat terrain. With 3-6 months of regular riding, this typically improves to 14-17 mph. Consistent training over a year can push average speeds to 17-20 mph for dedicated riders.
How do I calculate calories burned while cycling?
A rough estimate is that cycling burns approximately 400-600 calories per hour at moderate intensity (15-17 mph). The exact number depends on your weight, speed, terrain, and wind conditions. Using a power meter provides the most accurate calorie estimation.
