Time Trial Rules

Here are the 2011 ACA Time Trial Rules.

18.4 Individual Time Trial
The rules of this section are exceptions to the Individual Road Racing Rules. In all cases not specifically covered here, the Individual Road Racing Rules apply.
18.4.1 Road bicycles will be used with the following possible exceptions:
18.4.1.1  A bicycle with a fixed gear may be used instead of a bicycle with a freewheel. If so, a hand brake will be installed for at least the front wheel.
18.4.1.2  Riders may use upturned or forward pointing handlebars (i.e. cowhorn, tri bars).
18.4.2    The start order may be random, by seeding, or by order of registration.  Each rider will know their start time at least 15 minutes before his/her start.
18.4.3    The riders will all start in the same fashion, either with a holder or with one foot on the ground.
18.4.4    A rider arriving late at the start will only be allowed to start if it does not interfere with a scheduled start. The rider’s time will be based on their appointed start time.
18.4.5    No rider may ride closer that 25 meters behind and 2 meters to the side of another rider.
18.4.6    A rider attempting to pass another rider must complete the pass within 500 meters; otherwise he must drop back at least 25 meters behind the other rider.
18.4.7    Support vehicles, if allowed, must remain at least 20 meters behind their rider unless the rider is stopped.
18.4.8    Feeding is normally not allowed in Time Trials.
18.4.9    Team Time Trials use the same rules as Individual Time Trials. The number of riders on a team, and rules on which rider is timed, must be made clear in the race announcement.
