Answer 1

Any athlete who runs outside the assigned lane is subject to disqualification
All athletes will participate in the Shuttle Relay. Thereafter, athletes may enter a maximum of 5 and a minimum of 2 events
In each track event (except relay events) there will be 3 competitors A, B & C of which A will be the stronger athlete.
Relays are no longer double points, just normal A and B race points awarded.

Answer 2

Track and field is a series of running, jumping and throwing events that take place over a designated number of days. The specific competitions in the sport are generally referred to as meets, or alternately, track meets. The running competitions are held on a 200- (indoors) or 400-meter (outdoor) rubberized track. Tracks can be shorter or longer in distance, but it makes them ineligible to hold national or international championship meets.

All running events are run in a counter-clockwise direction. All distance events (except the 800m) start on a curved line, so that every runner will have an equal distance from start to finish. The races begin with the shooting of a start gun, after which all runners may leave the start line and move to the inside lane. The 800m usually begins in lanes.

The competitors continue around the track for the designated number of laps. A lap is considered one full circle of the track, during which time the competitors will repeatedly pass the eventual finish line. When the first runner passes the finish line for the penultimate time, a bell will ring to signal the final lap.

The first runner to cross the finish line wins the race.
