Is there anyone out there that could tell where I need to look for information on the HJ, TJ, LJ, and Relays. I just fell into the head track and field coaching position at the high school I teach at and I am the only coach on staff at this point in time. I can handle the distance runners, I feel comfortable in that area. If anyone could tell of any internet sites or books that would help my in the aformentioned areas that would be much appreciated.
