A rolling start is one of two modes of initiating a race; the other mode is the
There's no need to hire a timing official for rolling starts.
Rolling Start: In a rolling start, the vehicles are
already in motion when they cross the start line (DSS). It is a Special
Section start (DSS) without a start referee.
Standing Start: In a standing start, the vehicles begin
the race from a stationary position at the DSS. Usually with the help of
the start referee.
The actual start time at the DSS will be identified automatically by the
There are two types of rolling start on RoadbookRally.com platform:
Open Rolling Start: Competitors can start at any time
after the section "First competitor start at" time. You would not have
to set start times for competitors. Competitors would gain access to the
roadbook after the section's “first competitor's start time”.
Rolling Start with Time Window: Competitors can cross
the DSS at the given time window (managed under the Event "Start list"
tab). Competitors will receive a time penalty for starting (crossing the
DSS) outside of their given time window. Keep in mind: sometimes the
roadbook will start with a liaison. Sometimes with the DSS. You have to
plan your arrival and start times accordingly.
The Special Section start time window is essentially the time frame within which
competitors must cross the start line (DSS) to officially begin the Special
Section. Here are some points to understand about the Special Section start time
Roadbook/track configuration rules:
Purpose: The start time window serves several purposes. It helps prevent
congestion at the starting line by spreading out the competitors'
departures over a period. This ensures a smoother start to the section
and reduces the likelihood of accidents or bottlenecks.
Flexibility: The start time window allows competitors some flexibility
in choosing when they want to start within the designated timeframe.
Preparation: Competitors should arrive at the beginning of the section
(roadbook’s first row) well before their designated start time window to
allow for warm-up and any necessary preparations. This ensures that they
are ready to start when their window opens.
Enforcement: Event organizers can enforce the start time window.
Competitors who start before or after their designated window may be
subject to penalties or disqualification by the organizer.
DSS shouldn't be placed at an intersection or a parking lot or anything like
that. Ideally, the rolling start (DSS) should be located on a straight line/road
to be as accurate as possible. The actual start (DSS) must be at least 300m
distance away from the roadbook starting point. This means you would need to
edit the roadbook so that the roadbook starts with a ~300m liaison and a bit
later there would be a DSS waypoint, to force the rider to cross it while
driving. Reason: to prevent unintentional start "detections" from competitors
waiting in the start area.
By default, all competitors will be
able to register for the event but they will not get access to any
sections/roadbooks. The organizer will be able to control when and who gets
access to the section (roadbook).
Organizer will have to set a "start time" for each competitor individually (for
each section). The roadbook becomes available 20 minutes before the competitor’s
start time. 12 hours after the start time roadbook access will be removed.
For example, if you set the start time for competitor #10 at 25.11.2023 10:25,
then he will get access to the roadbook at 25.11.2023 10:05 (20 minutes before
his planned start time).
The competitor has to cross DSS between 25.11.2023 10:25 and 25.11.2023 11:25
(his rolling start time window is one hour)
For results calculation, the actual precise start time will be identified
automatically by the competitor's GPS at the point where he crosses the DSS
