There was a book about high school training out, it had top high school kids and what they ran. Rupp I believe was in it.
He ran about 60-70 mpw
standard oregon type speed work
lots of drills before and after ever practice and meet.
Alberto always had Rupp doing drills and hurdle stuff after races.
Rupp would warmup for an hour to and hour and 1/2 before most races.
Workouts after races even in high school.
He did a jog the straight race the curves 3000m in sub 9 minutes.
Every race had very a specific plan (I had two of my H.S. d1 level kids beat rupp in a race, he was a soph, they were seniors) Alberto calling out all the time stick to the plan.
Alberto ran a group of high school elite kids from the area all older then Rupp. Including Alec wall (FL)ran 8:17 hs 3k and Chapa's kid who ran 3:50, 1:51 and Mike Mcgrath who ran 1:48 Rupp would chase these guys who were older and just get faster every run, he ended up beating them all.
They would also Prey before each race.
Rupp ran 9:07 for 3k in junior high of little training for the CYO youth team.
Rupp's mom won the Oregon state meet for Xc in h.s. twice
