Thanks for all the advice so far,
I've relayed it to the athlete in question.
Seems to be leaning towards 400/800 for this coming track season... we'll see how it goes.
Experiment with the following if the athlete wants to continue on with the 800m:
60 miles per week/12 mile long run max
more work of continuous 800m with change of pace
200m in 27 into 400m in 75 into 200m in 27
(2:09 total time)
Drills -- really work these, have the runner do a dedicated session where they are doing 4 sets of high knees, butt kicks, kick outs, skipping, and backward running until they are doing the drill for 200m (takes a minute or so)
200m sessions with low rest...8-10x with 60-90 seconds moving the paces down so that you are relaxed at pace without full recovery
instead of tempo something like 12-16 400m in 80 with 15 seconds rest.
Basically increasing the quality while working the strength system. I would keep mileage above 50 as world class 400m guys might do for their base training...
Great suggestions Old Sub 4. So this is primarily for a 400/800m type athlete? Esp the 12-15 400m in 80 with 15 seconds rest; do you mean for such a runner to forego sustained tempo efforts like 4-5 miles continuous and make do with that particular nature of training for threshold development?
