How does a road race start?
B · Beginner · The race · 3 of 4The race is started by a gun, cannon, air horn or another clear signal. On "On your marks" the athletes gather behind the start line as the organisers direct. Nobody may touch the line or the ground beyond it with any part of the body. Big fields are given warnings five, three and one minute before the start.
How it works
- The signal: "the firing of a gun, cannon or air horn or by initiating another distinctive and unambiguous start signal suitable for the relevant competition". Any other signal has to be approved in advance by World Athletics.
- The command: the commands for races longer than 400 m are used. There is "On your marks" and then the signal, with no "Set".
- Standing: it is a standing start. There are no starting blocks.
- Assembling: "the athletes shall assemble on the start line in the manner determined by the organisers".
- Behind the line: "The Starter shall ensure that no athlete has their foot (or any part of their body) touching the start line or the ground in front of it, and shall then start the race."
- The countdown: "In races which include a large number of athletes, five-minute, three-minute and one-minute warnings before the start of the race should be given."
- False starts: the commentary says starters and referees should avoid being over-zealous with the false start rules outside the stadium, because recalling a large field is difficult and often impractical. Where there is a clear and wilful breach, the referee may act against the individual during or after the race.
- A failed start signal: the commentary adds that if the start mechanism fails and the timing may not have started, a recall may be the best option where it is practical.
- The clock: the official time runs from the start signal.
Tricky cases
Is there a "Set" command?
No. For races longer than 400 m the command is "On your marks" followed by the signal.
Can a toe be on the start line?
No. No part of the body may touch the line or the ground in front of it.
One runner in a field of 20,000 goes a fraction early. Is the race called back?
No, not normally. The commentary accepts that a recall is often impractical. The referee may deal with a clear and wilful breach by that runner during or after the race.
Does an athlete's time start when they cross the start line?
No. The official time starts with the start signal.
Why the rule exists
A long race does not need the precision of a sprint start, and a field of thousands cannot be set like eight sprinters. The rule keeps the one thing that matters: nobody begins ahead of the line. The countdown lets a large field settle before the signal.
