Peloton Project Case Study

Peloton Project Races to a World Record

First-of-its-kind cycling research shows unexpected results

A peloton is the main field of riders in a road bicycle race. Riders in the peloton can take advantage of the effects of slipstreaming, or drafting, behind other riders. Air resistance prevents cyclists from going faster on flat road, and slipstreaming can save up to 50 percent of their energy.

That was the assumption, at least.

Find out what happened when Professor Bert Blocken of Eindhoven University of Technology (Netherlands) and KU Leuven (Belgium) set out to fill the information gap.
