What is a cycling speed calculator?
The cycling speed calculator converts ride distance and time into average mph and kph. Useful for tracking ride performance, comparing routes, and planning longer rides.
Formula
Speed = distance / time. Convert mph ↔ kph by multiplying by 1.6093 (mph → kph) or 0.6214 (kph → mph).
Worked example
25 miles in 1h 30m: speed = 25 / 1.5 = 16.67 mph (26.82 kph).
How to use this calculator
- Enter distance and unit.
- Enter total ride time.
Frequently asked questions
What's a good cycling speed?
Casual: 10-12 mph (16-19 kph). Recreational: 13-16 mph (21-26 kph). Trained: 17-20 mph (27-32 kph). Strong amateur: 20-25 mph (32-40 kph). Pros: 25-30 mph (40-48 kph) sustained on flats.
Why is climbing speed so much slower?
You're doing more work per unit distance — overcoming gravity. A 5% grade can cut speed in half. Strava and similar apps separate climbing time from flat time for honest comparisons.
Average vs moving speed?
Average includes stops; moving speed only counts time the wheels were turning. Most cycling computers (Garmin, Wahoo) report both. Use moving speed for performance tracking.
