Ok here is my review of all of this.
I need to know a few things first.
What is your current height and weight?
I think you're doing way too much in the way of distance running and lower quality runs.
Are you able to maintain your bodyweight without the distance running or would your body weight go up alot if you stopped it?
If you can maintain your bodyweight without doing all of the distance running by watching what you eat then I have a workout program for you.
You say you want to run the 800 fast in the summer.
So start training now for it. The training you're doing is counter productive towards your goal.
You have to be getting more quality runs in.
Workout hard on 2 days per week, cut out all of the distance you're doing. That's not going to get you to a 1:52 in the 800 or better.
Here is the workout i devised for 800 runners to hit peak maximum times.
Monday(hard day #1) -
400- all out
2:30 mins rest.
400- all out
5mins rest
400- all out
2:30 rest
400- all out.
Run this 400 workout on a monday in anticipation of a friday race.
Add up each 400 meter time.. So if you ran 1:00 on all of them then that's a total time of 4:00.
WRite that total time down on paper as a reference point.. So write down total time 4:00....
Wednesdays workout.... Speed day.
8 by 40 yard dashes with 3 full mins in between.. Each one should be done all out.
Fridays workout.
4 by 200 meter dash workout.
200- all out.
21 mins rest... The 21 mins rest is designed in a way so that you are FULLY recovered before you run the next 200.. This is the quality day.. To allow for quality you have to take off a full 21 mins between each 200.
200- all out.
21 mins rest.
200- all out
21mins rest
200-all out.
Add up the total time for this workout. So if you ran them all in 25.00 then that's a total time of 1:40.
Write 1:40 down on that days workout sheet as the TOTAL TIME.
Then you take off saturday and sunday to rest.. No distance running. No jogging. Maintain your weight by watching what you eat. Lower quality runs will do nothing for the 800. It's only going to make you more slow twitch...
Mondays workout is the same exact workout the week before.
The 4 by 400 meter dash workout..
Weds workout is the same exact workout the week before... The 8 by 40 yard dash workout.
Fridays workout is the same exact workout as the week before. .. The 4 by 200 meter dash workout.
You keep doing this sequence of events over the course of the entire year. You keep striving to lower the total time in each workout. The rest times are kept the same for comparison.
Your goal should be to gradually get that total time in the 4 by 400 workout down to a total time of 3:40 with those exact rest times..
If you get that total time down to 3:40 in that workout then you now have the potential to run 1:51 in the 800.. But only if you can get that total time in that workout down that low.
You're making this way more complicated than it really is. Keep it simple..
And this workout is alot more complex than you give it credit for.
Let's run over why this works.
Notice how it's a 4 by 400 workout and not a 8 by 400 workout?
You want to run this workout exactly doubled as your race... So if your race is the 800 which it is then your workout in this should cover a total distance of 1600.
Doing exactly double produces better results. Because it's of a higher quality workout. If you did a 8 by 400 workout then that's going to produce a lower quality workout.
Each of those 400s are ran with minimal recovery time to mimic an 800 race.
The exact rest times of 2:30 , 5:00, and then 2:30 produces the best results..
They key here is to always start the next 400 when your rest time is up. Never start late or early. Make sure it's right at 2:30 , 5:00 and 2:30.. Time your rest times.
That 4 by 200 workout with the 21mins rest produces quality.... It's covers the same exact distance as your race. Notice how it's not a 8 by 200 and not a 2 by 200? It has to be the same distance of your race.
What you're doing here is over compensating. You're trying to run faster than that what your pace for the 800 would be. And you are because you're running each of these 200s all out. No slacking on these whatsoever.. Maximum effort at all times. It's the only way to be sure and it's the only way to produce the greatest results.
Now let's get into why I designed this on two days out of the week for the hard workouts.
Monday and friday are your hard days.. And then wed is the easy day.
The natural human body needs 96 hours of full recovery between workouts to produce the greatest results.
The time frame between monday and friday is exactly 96 hours. So it relates. See how that works?
Wed is just a speed day of 40s so it's really not going to effect how you feel on mondays and fridays..
Cut out all of the distance running.. Etc... Do these exact workouts and you're going to run 1:51 or even better depending on what bodyweight you can maintain.
