Top speed, made visible.

Speed Matchups turns reported speeds into proportional visual comparisons. It is designed to answer a simple question clearly: if two competitors immediately reached the selected speeds and held them, what would the race look like?

How speeds are selected

Each racer is labeled as a measured record, reported maximum, research-based figure, approximate estimate, or representative comparison preset. Source links are provided on dedicated matchup pages. When sources describe different conditions or publish a range, the site uses a clearly labeled comparison value instead of presenting it as an exact universal maximum.

How the race is calculated

Race time is distance divided by speed. Every racer begins at full selected speed and maintains it to the finish. The animation is proportional to those calculated times, including the distance covered by a losing racer when the winner finishes.

What the simulation leaves out

The races do not model acceleration, fatigue, reaction time, terrain, motivation, turning ability, weather, or individual variation. They are educational comparisons, not predictions of real encounters or safety advice.

Editorial approach

Measured records are preferred when they exist. Reported animal maxima are treated cautiously because testing conditions and definitions differ. The site distinguishes those figures from measured records so visitors can enjoy the comparison without mistaking every number for laboratory precision.
