We see drafting a lot in pro races when a peloton pack rides tightly together, often alternating positions and sitting tight on someone’s else back wheel. But why do they do it?
It works
And not just an ‘elite sportsperson’, 0.001 of a second amount of working. The difference it makes is huge: the rider drafting will expend 20-40 percent less energy.
The other more surprising benefit is that it also works for the person doing the leading too; the rider that’s drafting reduces the turbulence coming off the leader and less swirling air behind you makes you more aerodynamic.
Explaining drafting gives you a chance to use the word ‘vortex’
You create vortices as you cycle forward, aka a low-pressure area with no wind. It’s a little pocket of air, carrying you along and doing loads of work for you. Awesome.
