I'm a first year teacher and I'm also going to be head coach this year. I teach at a really small school on an Indian reservation, and despite their familiarity with Billy Mills, all my runners want to be sprinters. I'm a distance runner, and there were a total of about 5 sprinters on my college team during my four years there, so I don't have a whole lot of familiarity with sprint training. I'd love to make these kids as fast. What do I need to be doing?
