Cycling Speed Calculator Description

Introduction

The Cycling Speed Calculator helps you assess your riding efficiency using time, distance, and optional terrain correction. Whether you're training, racing, or tracking casual rides, this tool offers precise speed metrics with visual feedback.

Core Speed Calculation

Formula

Average Speed = Total Distance / Total Time

• Total Distance: Enter in kilometers or miles.
• Total Time: Convert time into hours (e.g., 1h 30m = 1.5h).

Terrain Adjustment

Apply a terrain factor to modify the raw speed based on riding surface:

Adjusted Speed = Raw Speed × Terrain Factor

• Flat Road: 1.00
• Hilly Terrain: 0.90
• Mountainous: 0.75
• Downhill: 1.10

Segmented Speed Analysis

Split your ride into segments to measure pacing and consistency. This is helpful for identifying fatigue points and assessing terrain impact.

Case Study: Road Cyclist

• Segment 1: 30 km in 0.9 hours
• Segment 2: 30 km in 1.1 hours (terrain factor: 0.9)
• Segment 3: 30 km in 1.0 hours

Raw Average Speed:
90 km / (0.9 + 1.1 + 1.0) = 27.27 km/h

Adjusted Segment 2:
30 km ÷ (1.1 × 0.9) = 30.30 km/h

Case Study: Mountain Biker

• Uphill: 10 km in 0.8 h × 0.75 = 9.375 km/h
• Flat: 15 km in 0.6 h = 25 km/h
• Downhill: 15 km in 0.4 h × 1.10 = 41.25 km/h

Edge Cases

• Zero Time Input: Triggers an error (division by zero).
• Short Bursts: Auto-scales durations under 1 minute for sprint tracking.
• Mixed Units: Automatically converts miles to km if speed output is km/h (1 mile = 1.60934 km).
• Incomplete Segments: Skipped in adjusted speed but shown for review.
• Negative Values: Rejected and flagged with tooltips.
