Go easy Gloopzilla…that was back in the 80s! My memory fails me, but … yes 150m may be actually a better distance to work over. When it’s only 150m you tend not to lose concentration or technique.
We were modifying the volumes as fitness permitted.
But I typically would tend to mix plyos with light incline sprints on a grass surface.
So a set might look like 1-2 sprints over 150m slow walk back, (about 5mins between runs), then walk down to side of hill and stretch soleus, gastrocs, quads, hips etc. When ready start: Double-foot bunny jumps up hillside. Maybe 10 contacts up . . . and 10 double-foot contacts down.
I think the downhill hops are important if you can do them safely (without slipping) because they add that element of loaded eccentric training.
So one set could be: 1-2x150m run + 2-5 x (10 hops up + 10 hops down).
Play with the number of runs and the number of hops depending on what you’re looking to get out of this type of training which will depend also on what event(s) you run (60m, 100m, 200m 400m). If you were training the 100m you might bulk up on the jumps but not do too many sets.
If you were training for the 400m you might contemplate eventually up to 6 sets of 2x150+2x(10 hops up, 10 hops down). Take 8-10 minutes between sets.
JUst one other note, we used a motorbike kidney belt or a weightlifting belt to brace lowerback, as much as an awareness thing to ensure the athlete kept good posture.
I hate to be prescriptive because so much depends on the athlete’s training age and the type of training that has been accomplished: ie: whether the core is stable, what the co-ordination, flexibility, mobility and technique are like.
As a rule I would start on the minimum volume of sets/reps.
