What are the rules in a bunch sprint?
B · Beginner · The road race · 2 of 6Hold your line. A rider must not leave the lane they chose when they launched the sprint if doing so obstructs or endangers others. A rider who does is relegated to last place in their group and fined, and in serious cases can be disqualified. Pulling a jersey or using a head or elbow counts too.
How it works
- The rule: riders are "strictly forbidden to deviate from the lane they selected when launching into the sprint and, in so doing, obstructing or endangering others".
- Both parts matter: the offence is deviating and, by it, obstructing or endangering.
- Irregular sprinting: the table of race incidents adds "pulling the jersey or saddle of another rider, intimidation or threat" and blows from the head, knee, elbow, shoulder or hand.
- The usual penalty: a fine and "relegation to last place in the rider's group".
- In a stage race: a penalty in the points or mountains classification as well.
- A yellow card: may be added at the top classes of event.
- Serious cases: the commissaires' panel may eliminate or disqualify the rider.
- The result: otherwise the order across the line stands, read from a photo finish.
- Vehicles: none may overtake the riders in the last 10 kilometres.
The glossary has the sprint, the peloton, relegation and disqualification and the points classification.
Tricky cases
A sprinter drifts across the road but nobody is near them. Is that an offence?
No. The rule is broken when the deviation obstructs or endangers others.
The winner is relegated. Do they lose only the win?
No. They are placed last in the group they finished in, so in a bunch of 80 they are classified 80th.
Can a sprinter move across before starting the sprint, to find a wheel to follow?
Yes. The lane is fixed from the moment the rider launches the sprint.
Is leaning on a rival with a shoulder allowed?
No, not as a blow. The table lists blows from the shoulder among irregular sprinting. The commissaires judge the contact.
Why the rule exists
A bunch sprint puts dozens of riders shoulder to shoulder at 70 kilometres an hour, and a rider who swerves can bring down everyone behind. The rule makes a sprinter's path predictable from the moment they start their effort.
