800 meter training program-please critique

Okay, i have done some research and have put together a training program.It primarily focuses on increasing my speed and speed-endurance as that is what i need to get better at the 800 meters.I want to get down to a 24 second 200 and around 53 second 400 in a few months.So here it is

Day 1
20yard sprints-till time drops off
Low Box Depth Jumps
Box Squat Jumps
2*800 meters at 3:00-3:15 pace

Day 2
Box Squat 5*3 50%
Box Squat-work up to max single
ISO Deadlifts
Back Extensions

Day 4
40 yard sprints-till time drops off
Depth Landings
Box Squat Jumps
4*300 meters at 48-50seconds

Day 5
Full Squat 4sets of 5 reps-each week add 1 set and reduce a rep
Romanian Deadlifts-same
GHRs
Back Extensions

Day 6
8*100 meters at 13-15 seconds
after last rep begin jogging a half lap and then sprint the last half of the lap as fast as possible

Days 3 and 7 are rest days

please post any comments and critique

please, can some one tell me if this will greatly increase my speed (as i have never done short sprints before to increase speed always like 200 meter sprints with 2 minutes rest) and hopefully keep my endurance steady.Just please give me some feedback.
