* The length of the track and the width of each lane are specified by the IAAF. * If the number of competitor is more than ten in the 100 meter sprint event, then, preliminary heat races are held. The winners or the top sprinters will qualify for the next round. * Any sprinter with a false start will be warned after the first attempt. After the next false start, he will be disqualified. * The records may be made only on the track which is made of such a substance which allows runners to run with spiked shoes. * The athlete is not given any credit if he or she does not finish the race. * The time of the event has to be measured with a permitted automatic timing device. * The radius of the outside lane of the track cannot be more than 50 meter. * No athlete is permitted to run inside the inner curve of the track. Even stepping on the inner line of the track is not allowed.

by speed training. most common way is to sprint for 100m jog for next 100m sprint another 100m jog 100m. do this continously for 30mins. do it at least 3 times a week. your speed will improve. maybe not significantly but it will improve.
