“…This type of behaviour has previously been observed with other drafting bluff bodies such as racing cars [90]. Perhaps surprisingly recent investigations by Barry et al [93] show that the wake of a trailing cyclists remains largely unchanged compared to the wake of an isolated rider. This is despite significant differences in upstream flow conditions that exist for isolated and trailing riders and highlights the robustness of the formation of the large-scale wake vortices.…”

“…Second riders typically experience a 30-45% reduction in drag below their baseline, while subsequent riders typically experience a 35-55% reduction compared to their baselines. For riders behind the leader, not only does the wake of the rider that they are following reduce the pressure ahead of them, but the high-pressure region in front of the rider following them also reduces the pressure differential, further contributing to the total reduction in pressure drag [37,38,45,53,58,93,95].…”

“…Barry et al [14] reported mean drag savings of 5%, 45%, 55% and 57% for four cyclists positioned behind each other, respectively. Barry et al [15] also experimentally analysed the flow structures occurring in drafting. Parallels between tandem cycling and the physics of drafting can also be drawn with the work of Blocken and Toparlar [3] and Blocken et al [4], who investigated the aerodynamic benefit for a cyclist by a trailing/following car and motorcycle, respectively, which they attributed to the subsonic upstream disturbance typical of the elliptical character of the governing Navier-Stokes equations [4].…”

“…Aerodynamic optimisation has become a key element of competitive cycling in recent years [1]. Numerous studies have been conducted to quantify and understand aerodynamic drag in cycling [2][3][4][5][6][7][8][9][10][11][12][13]. It has been shown for a competitive able-bodied cyclist that drag reductions in the order of 20% with respect to a traditional athlete's posture can be obtained through refinements and adjustments of cycling positions/postures, while remaining within the boundaries of the rules set by the union cycliste internationale (UCI) [14].…”
