n. The ''team manager'' of a cycle racing team
Wikipedia
A directeur sportif ( French for sporting director, although the original French term is often used in English-language media; plural directeurs sportifs) is a person directing a cycling team during a road bicycle racing event. At professional level, a directeur sportif follows the team in a car and communicates with riders, personnel and race officials by radio.
The directeur sportif warns of obstacles or challenging terrain, updates the team on the situation in the race, and provides mechanical help. The car carrying the directeur sportif also usually carries a bicycle mechanic with spare bikes, wheels and parts. It also carries spare water bottles, food and medical equipment.
In recent years the role has increased, in keeping with better team cohesion, tactics and communication and telemetry equipment. The directeur sportif can have split times, find where riders from other teams are in the race, and dictate orders to riders. This has made teamwork and tactics more important.
A directeur sportif can also be involved in the riders' training and racing programme. Many are former professionals, such as Johan Bruyneel and Sean Yates.
Several directeurs sportifs are also associated with famous riders whom they have nurtured. Patrick Lefevère with Johan Museeuw and Tom Boonen, Cyrille Guimard's relationship with Bernard Hinault, and later Laurent Fignon; Jean de Gribaldy with Sean Kelly and Joaquim Agostinho; and Bruyneel with Lance Armstrong are examples.
