How would you structure a sprint workout to develop raw speed. How long to warmup, what distance to sprint, how many reps? sets? How often each week to develop raw speed
Your age?
Did you participate in high school track & field? I doubt it. You stated a 76 400m personal best. You really do not want to train as a sprinter. It sounds like you want to do sprint workouts while you log, most likely 75 plus miles a week.
Your age matters. Sprinting is like ballet. Nearly all great ballerinas started at age 3 or 4. I assume you are past age twenty-five. The older one is, the more developing sprinting coordination is difficult, especially if you insist on training as a long distance runner. I assume you did not participate in explosive moment sports growing up. Sprinting is mostly physical strength as strength relates to body weight and neuromuscular coordination.
I started running at 30 and sprint significantly faster than others at/above my performance (16 low 5k) after sedentary for many years. Talent, and ratio of FT to ST fibers doesn't go away. Either you have it, or you don't.
You are right with all your assessments except with age - it's not age that matters most, but ratio of FT fibers (genetics). Sure, when you talk about becoming an elite sprinter - I agree, but a middle distance or distance runner can get all the speed he needs even if he starts running late in life.
OP is like Salazar, just with way less talent - a pure slow-twitch monster. Therefore, I wouldn't prescribe him any sprints at all - his body just isn't made for it. He has almost no FT fibers, just enough to survive. A few million years ago he would have been a persistance hunter (running animals to death), and not a rabbit catcher. What he needs is high mileage, to stimulate his muscle fibers. At 15 mpw, he neither got fast, nor good at longer races, which is exactly what I expected.
Also, sprinting on hills is much easier since it doesn't require much coordination, just raw power. But I still don't think OP should focus on that, he wouldn't be fast doing them anyway.
