There was an old thread that detailed some of Lance Brauman’s training. It had samples of running workouts and weights workouts for Wallace Spearmon and Tyson Gay. It was mainly Intensive Tempo/Controlled Speed Work and thousands of meters of it if memory serves me correct. I don’t think the thread can be found now but I am sure someone on here has saved it.
I was told Clyde Hart’s training was an example as well.
