Get in line early, there's usually a crowd. Where to put and retrieve your warmups. Where to meet your companions. The location of the finish area, if it is adjacent to the start. Try to get some knowledge of the finish chute system.
Some races use different chutes for different ages and sexes.
Find out which chute you must use and exactly where the line is relative to the chute, banners or other landmarks. Warming Up Warming up before the event has both psychological and physiological benefits. Warm up may help you to prevent injury during the run by having your body prepared and ready to go. Psychologically, it may help you to become clearly focused on the event and on your body. Often being in the crowd and being primed and ready to go can make you go crazy the first mile and run 30 seconds to a minute per mile faster than you wanted.
