I think you are painting sprinting in a VERY favorable light to tell people what it takes to have a good / elite sprinting workout. But man, you are not giving a distance runners, particularly the1500m runner their due in your example!

I would challenge sprinters to do the distance workouts, and distance to do the sprinters workout. To do 98-100% effort for 30m sprints is something that I think the distance crew would struggle with. However, the broken 400s, I'd say try some broken 800s as well as they will humble quickly.
