How does the sprint work in track cycling, and why do the riders go so slowly at first?
B · Beginner · The track and the sprint events · 2 of 8Two riders race over three laps, and only the order across the line matters, not the time. So they ride slowly and watch each other, since the rider behind has the slipstream and the surprise. Riders are seeded by a flying 200 metres time trial. From the semi-finals each match is the best of three races.
How it works
- The race: "a race between 2 to 4 riders over 2 or 3 laps". Three laps on tracks shorter than 333.33 metres.
- Qualifying: a 200 metres time trial with a flying start selects and seeds the riders.
- The rounds: knockout heats. The minimum format has straight quarter-finals, then semi-finals and finals as the best of three.
- Two finals: for first and second, and for third and fourth.
- Starting position: by lot. The rider who draws number 1 starts on the inside. In the second race they swap, and for a decider there is a fresh draw.
- The start: by whistle.
- The first half-lap: the inside rider must lead "at least at walking pace" until the pursuit line on the far side, unless overtaken.
- Standstills: at most two in a race, of no more than 30 seconds each. If the leading rider will not go on when told, the other wins the heat.
- A walkover: if a rider drops out of a two-rider heat, the opponent comes to the line and is declared the winner without riding.
- Fair riding: the rules of the sprinters' lane apply once the sprint begins.
The glossary has the sprint, the 200 m time trial, the standstill, the sprinters' lane and draft.
Tricky cases
Is the winner the rider with the faster time?
No. The winner is the first across the line. Time matters only in the 200 metres qualifying.
Can a rider stand still on the track for as long as they like?
No. A standstill may last 30 seconds at most, and only two are allowed in a race.
Does the same rider have to lead in every race of a match?
No. The rider on the inside leads the first race. In the second the other takes the inside, and a third race has a new draw.
Two riders set the same time in qualifying. Who is seeded higher?
The one with the better time over the last 100 metres. If that cannot be recorded or is also equal, lots are drawn.
Why the rule exists
Leading is a disadvantage, because the rider behind is sheltered and can choose the moment to jump. The slow opening laps are the two riders trying to force each other to the front. The rules allow that game but cap it, with a minimum pace at first and a limit on standing still.
