Trevor L Taylor, a former Division I athlete who has trained in road cycling, values repeatable methods over improvisation, and the team time trial is the road discipline that most rewards rehearsed teamwork. A squad leaves the start ramp together, shares the work at the front through a fixed rotation and races the clock as a unit. This entry explains how the rotation works, how the event rose and fell in the major stage races, and how a recent change to the timing rule altered its tactics.

How a team rides against the clock

In the classic format described by Velo, all eight riders on a team roll down the start ramp together1 and ride in a tight line. Teams set off at intervals, so each squad is racing the clock and the times of rivals it cannot see. For decades the team’s time was taken when its fourth or fifth rider crossed the line, which meant the group had to stay together as long as possible and could afford to drop only a few riders.

The engine of the event is the rotation. In an individual time trial a rider usually aims for a steady effort near threshold. In a team time trial, according to an analysis published by TrainingPeaks, each rider instead takes short turns pulling the group2 at much higher power, then swings off and recovers in the shelter of teammates. Data from a professional rider showed pull phases that can exceed 130 percent of functional threshold power, separated by rest periods sitting in the line. The aim is a team speed that is consistent and higher than any one rider could hold alone.

The shelter is what makes that possible. Velo, summarising wind tunnel and simulation work by the engineer Bert Blocken, reported that in a nine rider team time trial line the ninth rider enjoys a 58 percent benefit3 in the energy spent overcoming air resistance, compared with riding alone. The drafting and pacelines entry explains that physics more fully. A good team uses the savings to let its strongest riders take longer turns while lighter climbers take shorter ones, so that nobody blows up before the finish.

Good team time trialling therefore depends on rehearsal as much as fitness. Riders need to know how long each teammate can pull, how close to sit to the wheel ahead and how to swing off without disrupting the line. Teams build special equipment for the day as well, from matched time trial bikes to aero helmets, because a whole group now rides in the exposed position at once. Spacing matters too: a gap of even a wheel length surrenders much of the shelter, so riders practise holding a close, steady line at speeds where a touch of wheels would bring down several teammates.

Rise, decline and return

The team time trial has a long history in both amateur and professional racing. At the Olympics it was raced over about 100 kilometres, and Cycling Weekly recalled that four Swedish brothers, the Petterssons, took the silver medal in the 100km team time trial4 at the Mexico City Games in 1968 and then won three straight world titles in the event.

In the Tour de France the discipline was once a fixture. Cycling Weekly noted an unbroken streak of TTTs in the Tour from 1976 to 19955, including 153 kilometres of team time trialling in 1978 alone, against just four team tests across all three grand tours in the 13 years before its 2018 article. That scarcity created a problem for teams, which had little reason to invest in specialist training for a stage that appeared so rarely.

Organisers had their own reasons to cut back. We Love Cycling suggested that race directors believed spectators preferred bunch sprints and mountain duels, and that the team time trial is the most technical of all styles of road racing6, demanding coordination and dedicated practice that riders may not want to put in. The same article pointed out that the 2023 Tour route had only one individual time trial, covering less than one percent of the race distance.

The event has since come back. Cyclingnews reported that the 2026 Tour would start with a team time trial in Barcelona7, on a course finishing near the stadium built on Montjuïc hill for the 1992 Olympic Games. When the stage was raced, The Guardian reported that Visma Lease a Bike won the 19.6km team time trial8 and put Jonas Vingegaard into the first yellow jersey. The women’s race is following: The Guardian also reported that the Tour de France Femmes will hold its first team time trial in London9 in 2027, on a circuit of about 18 kilometres finishing on the Mall.

The new timing rule and what it changes

The modern revival came with a twist. Under the format Tour organisers have used at Paris Nice since 2023, and applied at the 2026 Tour, each rider’s finish time is recorded individually and the stage is won by the team whose fastest rider reaches the line first. Velo described the older approach in one line, saying the collective was only as strong as its 4th or 5th man1, and argued that the new rule rewards both individual strength and collective planning.

In practice the change turns the closing kilometres into something like a sprint leadout. Teams with an overall contender spend their strongest riders early, then deliver the leader to the final section with fresh legs. Velo noted that the format should also make it harder for a single dominant team to fill the top places in the overall standings on the first day.

Opinion on the change was divided, Velo observed, between those who saw new life in an old format and those who would rather have retired it. Either way, the essentials of the event are unchanged. A team still needs a practised rotation, riders who know their limits and equipment that keeps a whole line slippery in the wind. Those demands link the team time trial to the individual time trial and to the power meters teams use to plan each pull. At its core the event is a test of whether a group can turn private fitness into shared speed.
