Then maybe right now you are in 2:02 shape.
The key to being able to run a fast 800 is not the ability to do 10 x 200 with a 1:3 work:rest ratio. They key is to be able to extend that pace to longer and longer reps.
The workout you posted indicates that you have decent anaerobic power and decent ability to recover from those short anaerobic bouts. This season, you might be good for 1:56 ish, but you have to do the fundamentals. You need to develop anaerobic endurance and aerobic power.
Sessions for 800m specialists to develop aerobic power:
-VO2 max type intervals of 2-3 min (600-1000m) with longish (1:2 ratio) recovery. No need to go faster than 3200m race pace (or for your purposes, add 10-12 seconds per lap to your 800 rp.)
- Fartlek on the roads or trails.
- Longish hills with a jog down recovery. Work on your mechanics: upright posture, knee lift, bouncing off the balls of your feet.
- Do not overcook these workouts. The rest I listed is much longer than for traditional VO2 max training (which is usually 1:1 ratio). Especially early in the season, it's ok to give yourself long recoveries on these sessions.
Sessions for 800m specialists to develop anaerobic endurance:
- The sessions listed above will all have an anaerobic component to them (especially if you take long rests)
- Reps of 300-600 @ about mile race pace (or 5-6 seconds per lap slower than your 800 best).
- High volumes of short reps with short rest: 20x100@ 800 rp with 30 seconds rest or 20 x 200 @ mile rp with 30 seconds rest.
In reality, fast stuff is not needed at all during the base period (sounds like you are running indoor, so this might not apply to you. I had a boy jump in an all comer meet the weekend before we started track practices in February after doing only base type work. He had never gone faster than 32 seconds for a 200 in his pre season training from Dec-Jan. He ran 1:58.2 in the all comer meet. He later went on to go 1:56.3 and split a 48.3 on a relay.
