Rules and regulations of Relay race competition

Each runner has to hand off the baton to the next runner within a firm zone, generally marked by triangles on the track. In sprint relays, runners normally use a “blind handoff”, where the second runner stands on a mark line predetermined in practice and begin running when the first runner hits a visual point of the line on the track (generally a smaller triangle). The second runner opens her hand following her after a few strides, by which time the first runner supposed to be caught up and able to hand over off the baton. In the middle-distance relays or longer, the runners start by jogging while looking back at the incoming runner and holding out a hand for the baton.

A relay race team may be disqualified from a relay for the following reason...
1. Improperly overtaking the another competitor
2. By preventing another competitor from passing
3. Willfully impeding, inappropriately crossing the course, or in any other way
4. Or by interfering with the another competitor
5. Making the two false starts (or in some cases only one)
6. Making an inappropriate or improper baton exchange
