Cycling time trials explained: racing against the clock
Overview
An individual time trial is cycling's race against the clock: riders start separately and their elapsed times are compared rather than racing as one peloton.
How it works
Because there is no normal peloton shelter, aerodynamics, pacing and a rider's ability to sustain power become especially visible. Courses can still vary from flat and fast to rolling or climbing-heavy.
Key tactics
Time trials can reshape a stage race because general-classification riders may gain or lose significant time without the usual team tactics of a mass-start road stage.
Race or rider context
Equipment and conduct are governed by current UCI road regulations. The cited current rule also requires following vehicles in road individual time trials to remain at least 25 metres behind riders.
Why it matters
Time trials connect naturally to articles on Grand Tours, aerodynamics, power meters, specialist riders and equipment regulation.
Refresh and safety boundary
Technical regulations can change and should be refreshed against current UCI rules. This article explains competition structure and does not provide unsafe advice for riding aero positions on public roads.
