Technical Q&A with Lennard Zinn – The aerodynamics of drafting
Dear Lennard Zinn;Everyone knows you don't have to work as hard if you're drafting off the person in front of you. How does your work effort change if someone is drafting behind you?Here is why I ask: I always thought that if you were riding by yourself, then you had to work harder than if somebody was drafting behind you because as you move through the air, it flows past your bike and body and creates turbulence as it swirls around in the void of space behind you. This almost creates a suction behind you pulling you back against your forward progress (if my logic is correct).
