I wrote this on another thread but didn't get too many replies. This is copy of what I wrote since the subject is very similar.
Mon : Off or very easy and short
Tue AM: Short REPS of 45sec to 90sec. These are fast but controlled and grouped into sets to insure lactates don't get out of control. 2-3 min rest between reps and 5-7 min between sets.
Tue PM: 30 min THRESHOLD at 80-85% maxHR. 20/20 for warm up / cool down.
Wed AM: VO2 (5-6 x 1200 - mile repeats) at 90-92% maxHR at the end of each interval. 30/15min for warm up / cooldown
Wed PM: Short run with several strides and then into the weightroom for max strength
Thurs : Easy Distance (65-70% maxHR) of 60-80 min
Fri AM: Speed (10-15 x 60m-150m strides at 400m race speed keeping technique highest priority) 30/20min for warm up / cool down.
Fri PM: Easy Distance (65-70% max HR) of 60 min
Sat AM: VO2 very similar to Wed AM
Sat PM: THRESHOLD very similar to Tue PM then into the weightroom for max strength.
Sun : Long Run 2hrs
I am 25 years old with a very good base and seem to be very resistant to injuries. However I have only been on this schedule for several weeks and would appreciate all knowledgeable feedback. So far the amount of intensity has been more than I am used to however my energy level remains high and I seem to be able to recover very well since there are still 2-2 day periods of easier training. My new coach, who designed this schedule, has tried it on himself with success and is also well known to be very sound and educated.
My goals are for the indoor 800/1500.
The idea behind stacking the workouts together is this:
1) to keep all of those efforts within a 36 hour window so that any delayed soreness doesn't take effect during another fast workout, and
2) to apply that theory of converting the fast twitch type II fibers to work more aerobically by using them when exhausted, and
3) this allows to have 48-72 hour (depending on how you look at it) periods to fully recover. Often after only one easy day's recovery after a single hard session the legs aren't quite back yet.
