Olympics 2012 track cycling

Can someone summarise the rules of the sprint?

Race procedure
3.2.038 The start shall be given by whistle.
3.2.039 The rider on the inside of the track, unless overtaken, shall lead at least at walking pace and make
no manoeuvre to force his opponent through until reaching the pursuit line on the opposite side of
the track. A maximum of two standstills shall be permitted for each race. The maximum period for a
standstill shall be 30 seconds following which, the leading rider shall be directed by the starter to
continue. If he fails to do so, the starter shall stop the race and declare the other rider the winner of
the heat. In a three or four-up race, the race shall be immediately rerun as a two or three-up race,
without the relegated rider.

3.2.040 [abrogated on 1st January 2002].
3.2.041 Before the last 200 metre line or the start of the final sprint, riders may avail themselves of the full
width of the track but must nevertheless leave sufficient space for their opponent to pass and shall
refrain from any manoeuvres that could provoke a collision, a fall or cause any rider to ride off the track.
3.2.042 During the final sprint, even if launched before the last 200 metres, each rider shall remain in his
lane up to the finish, unless he has at least a clear cycle-length lead and shall not make any
manoeuvre to prevent the opponent from passing.
(text modified on 1.01.02).
3.2.043 A rider may not challenge or pass on the left an opponent riding in the sprinters’ lane.
If the leading rider leaves the sprinters’ lane and his opponent attempts to pass to his left, he may
not return to that lane unless he still has a clear cycle-length lead.
3.2.044 A rider passing on the right of his opponent, who is in the sprinters’ lane, may not crowd him or
cause him suddenly to reduce speed.

3.2.045 A rider starting the sprint outside the sprinters’ lane may not drop into that lane if it is already occu-
pied by his opponent unless there is a clear cycle-length lead.
(text modified on 1.01.02).
3.2.046 Should the leading rider drop down below the measuring line he shall be relegated unless he does
so involuntarily and unless, at that moment, the result may be considered a foregone conclusion.
3.2.047 If, in a three or four-up race, a rider behaves in an irregular manner to favour another rider, he shall
be relegated. The race shall be immediately rerun as a two or three-up race.
(text modified on 1.01.02).
Race stoppages
3.2.048 The race may be stopped only:
1) in the case of fall.
If the fall be intentionally caused by a competitor, that competitor shall be relegated or disquali-
fied from the tournament according to the gravity of the fault committed and the other competi-
tor declared the winner. In three or four-up heats, the race shall be immediately restarted with
the remaining two or three riders.
Should the fall have been caused by a competitor riding too slowly in a curve or by any other unin-
tentional fault, the race shall be restarted and the offending rider shall take the inside of the track.
If the fall is not caused by a competitor committing a fault, commissaires shall decide whether
the race is to be restarted with the riders in the same order or whether the positions at the time
of the fall should be considered final.
2) in the case of a puncture.
3) in the case of the breakage of an essential part of the bicycle.
In all of these three cases, the commissaires shall decide whether the race is to be restarted with the rid-
ers in the same order or whether the positions at the time of the incident should be considered final.
4) in the following cases:
4.a) If a rider loses his balance, falls or touches an opponent or the barrier, the race shall be
restarted and the rider in question shall take the inside of the track.
4.b) If the starter observes a flagrant infringement and stops the race before the bell rings to
indicate the start of the last lap, the commissaires may relegate or disqualify the rider
committing the infringement. The other rider shall be declared the winner or in the case of
a three or four-up race, it shall be restarted as a two or three-up race.
(text modified on 1.01.02).
3.2.049 If the rider committing the infringement is not relegated or disqualified, the race shall be
restartedand that rider shall take the inside of the track.

There are also 3 pages of tables indicating how the field is to be set out after the seeding time trial.
