So today at practice my team and I were doing 2x2400 progressive for a warmup, the last lap ending at a brisk pace and it got me thinking, what if for a workout, you did a 2000-2400 progressive run, and the last section would be done at race/goal pace.
Now the length of the section that you would run would be 1/4 of your race distance, so for the 800 you would do 200, 1600/400 3200/800 etc. And you would gradually increase the amount, so for the first workout you're doing 1-2, second workout 2-3, third 3-4 etc. Ideally building up to where you're doing overdistance of about 1 1/4 your race distance at goal pace while pre-fatigued, also, you're allowed rest of no more than double what you finished the last interval in, so say for example, you finished the last 400 in 65, then you would get 1:10 for rest, so on and so forth. I feel like this could create some beastly finishing kicks, and really get your strength up pretty fast. Plus, you can tweak it so once you hit the ceiling of 4-5 reps, you can increase the final speed, and the pace of the lead in.
1) Is this already a thing? I feel like it might be but I'm not sure.

2) Would this actually work as a legitimate workout? I mean there's really only one way to find out, but if someone has done something similar to this, I would love to hear your results.
