GPP Speed Work?

I’m coming up to the end of the GPP phase, and that means I will be starting some GPP track stuff.

This what I got from the GPP video, on week 5 for Wednesday:

6x10m flat on ground
6x10m from the push-up position
6x20m from the high start
1 set 4x20m easy, 20m fast, 20m easy
1x50m from highstart
(accel 20+maintain)

Total Volume 650m

My question, is what is the rest times between reps and sets in this? The only thing I would say to keep in mind is that amount of reps and sets, a realistic time? Anyone know good rest times for this.

Would a walk back, and 45 seconds between reps be ok? Then have 3 minutes between sets be good?

Remember, I cant be doing this all day, because I have other training parts to do, among other things.

Doesn’t the video say a walk back recovery is sufficient for the 10 and 20m runs? I’ve got to watch it again.
