The infield is generally the only provision for throws training. Even if it is not used for such at your own track, you are teaching dangerous habits if you permit your athletes to cross it in an undisciplined manner. These habits can lead to fatalities when they go to tracks where throwers commonly use the infield. Safety in these areas is the responsibility of thrower and runners, and their coaches alike. Don't be negligent in this respect.
Roads are hard surfaces which increases the likelihood of stress problems.
Keep a careful cheek on your athletes when high mileages and speed work is programmed. Athletes should run facing the oncoming traffic, even when running on pavements. Runners should be seen - especially at night by wearing light, bright or reflective clothing. Even in daylight with a low, bright sun from behind, the driver's vision is often impaired. Hurdling Care should be taken to see that improvised equipment of the types used particularly with novices is reasonably safe.
