Calculating wind drag in the cycling peloton – Source flowingdata.com
When cyclists ride in that big pack during a race — the peloton — the ones that aren’t leading get to ride with a reduced wind resistance. Researchers found out the magnitude of the reduction.
According to a new study published in the Journal of Wind Engineering and Industrial Aerodynamics, riders in the belly of a peloton are exposed to 95% less drag than they would experience riding alone. Which explains the sensation all riders describe of being sucked along by the bunch while barely having to pedal.
