Researchers at Heriot-Watt University, working with Ansys, part of Synopsys, studied how running formations influence aerodynamic drag in marathon events. Using Ansys Discovery to generate runner geometries and Ansys Fluent for computational fluid dynamics simulations, validated through wind tunnel testing, the team examined airflow around solo, single-file, and closely grouped runner formations. Led by Professor Bert Blocken, the research found that certain group formations aim to reduce aerodynamic drag, which may lower energy expenditure during long-distance running. The findings could support future research into race strategies, pacing approaches, and endurance performance for both competitive and recreational runners.
