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?
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.
