What is drafting in cycling?
When a cyclist rides directly behind another rider, the front rider punches a hole in the air. The rider behind faces less air, so they use less energy, up to about a third less. Teams take turns at the front so everyone gets rest. Birds fly in lines for a similar reason. Drafting is a great example of how teamwork uses physics.

Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. What is drafting in cycling?
The Big Idea
Racing cyclists ride in a tight line! The riders in back save energy. It's called drafting.
A Hole in the Air
Step one: A Hole in the Air. When a cyclist rides directly behind another rider, the front rider punches a hole in the air. The rider behind faces less air.
Saving Energy
Step two: Saving Energy. The rider behind uses less energy, up to about a third less. Teams take turns at the front so everyone gets rest.
Like Birds
Step three: Like Birds. Birds fly in lines for a similar reason. Drafting is a great example of how teamwork uses physics.
A Closer Look
Let's take a closer look! Breaks the wind. Saves energy. Less push. Share the work.
Quick Facts
Quick facts! Drafting also helps runners a little. Saves up to a third. Teams take turns. Birds fly in lines.
Think Like a Scientist
Now, think like a scientist! Ask a grown-up to set up a fan. Stand a large piece of cardboard in front of it. Hold your hand behind the cardboard. Do you feel less wind? That's drafting!
Outro
In drafting, a cyclist rides right behind another, who punches a hole in the air. The rider behind faces less wind and uses up to a third less energy. Teams take turns leading, like birds flying in lines. Science is amazing! The world is full of surprises. Keep asking big questions, and keep exploring with me!
