Zeitfahren

Zeitfahren, also known as time trial in English, is a competitive cycling discipline where individual riders or teams race against the clock over a set distance. The objective is to complete the course in the shortest possible time. Unlike mass start races where riders compete directly against each other on the road simultaneously, in a Zeitfahren, riders start at pre-determined intervals, typically one or two minutes apart. This prevents drafting, where a rider can conserve energy by riding behind another.

Zeitfahren can be contested on various terrains, including flat roads, rolling hills, and mountainous climbs. The equipment used is highly specialized, with riders often employing aerodynamic bicycles, helmets, and clothing to minimize wind resistance. The rider's position on the bike is also crucial, with many adopting an aggressive, tucked-down stance to further enhance aerodynamics.

There are two main types of Zeitfahren: individual time trial (ITT) and team time trial (TTT). In an ITT, each rider races independently. In a TTT, a team of riders works together, taking turns at the front to set the pace and shield their teammates from the wind. The team's finishing time is usually recorded when a certain number of riders, often the fourth or fifth, cross the finish line. Zeitfahren events are a prominent feature in professional road cycling tours, such as the Tour de France, Giro d'Italia, and Vuelta a España, and are also contested as standalone championships.
