One of the main problems I've dealt with since coming to Army is the frequency and severity of lower leg stress related injuries (due to the cadets walking, marching, and running in boots all the time). While it was warm enough we did most of our extensive tempo work (2x / week for long sprinters; 1x / week for short sprinters) on a grass field. Now that the temperature is dropping off though we'll be looking to other alternative means (pool, jump stretch stretch trainer circuits, etc.) to accomplish the same goal because I need to minimize our stress related injuries and don't want to put in more time than necessary on our indoor oval.
