FYI The samples appear to be taken from the second edition (1989) of the The Athletic Congress’s Track and Field Manual, Chapter Sprints and Relays, authors: Vern Gambetta, Gary Winckler, Joe Rogers, John Orognen, Loren Seagrave, Sonny Jolly.
The workouts are “for a high school sprinter running 100m in 10.7 to 11.0s and 200m in 22.6 to 23.0.” although to be fair it also says that they should be adapted to the ages and training abilities of the athletes.
That sample training schedule was written by Gambetta with a heavy does of Winckler thrown in. When that book was released this group were the Level 2 sprints/hurdles/relay instructors for USATF (actually TAC then).
