Cycling Pace & Power Calculator

Our estimator uses a robust physics model that accounts for key variables like aerodynamic drag, rolling resistance, and gravity. While real-world conditions can always present minor variations, the tool provides a highly accurate and reliable estimation of the power required and speed achieved for given parameters, making it an invaluable planning tool.

Absolutely! The Threshold Cycling Pace & Power Estimator is versatile. You can input parameters specific to road cycling, such as an upright or drop-bar position, or fine-tune inputs for time trials by selecting an aerodynamic position (e.g., aero bars) and specific road surfaces.

Basic calculators typically provide single outputs based on limited inputs. Our estimator goes beyond by offering a physics-based analysis, real-time "what if" scenarios via interactive sliders, dominant force identification, and comprehensive guidance on nutrition, hydration, pacing, and equipment, providing a holistic view of your performance.

Aerodynamic drag (CdA) is often the largest force a cyclist must overcome, especially at higher speeds and on flat terrain. Our tool allows you to adjust your CdA and instantly see how improvements in your cycling position or aero equipment can significantly reduce the power required to maintain a given speed, or increase your speed for the same power output.

Sustained cycling performance is heavily dependent on proper fueling. We include nutrition and hydration guidelines because understanding the estimated duration and intensity of your ride is crucial for planning your carbohydrate and electrolyte intake, preventing bonking, and ensuring you can maintain your predicted pace throughout your ride. It's part of our holistic approach to performance optimization.

Yes, it's designed for all levels of cyclists! Beginners can use it to understand the basics of power and pacing, helping them plan manageable rides and prevent overexertion. Experienced cyclists will find its detailed insights invaluable for fine-tuning their training, optimizing race strategies, and pushing their limits with precision.

We recommend using the Threshold Cycling Pace & Power Estimator regularly. Use it when planning new routes, before key training sessions, or prior to races to strategize your pacing, understand power demands, and simulate different wind conditions or gear choices. It's a dynamic tool that should be part of your ongoing cycling preparation.
