Just completed week 6 (8 total) of my heart/time based half train plan, repeating weeks 1 and 2 to time the 18 week plan for the Bayshore half on Memorial Day weekend.
Weekly Total 36.8 miles, 6:05 run training time, 32 min strength training.
Monday: 60 minute AB (Aerobic Base) run at my aerobic heart rate of 118 bpm, +/-5 bpm, run on a treadmill. 6.3 miles (by Garmin, usually a little more by the treadmill), average heart rate of 118 bpm. When I do these runs on the treadmill after I get warmed up I check my heart rate every couple of minutes and then determine if I need to adjust the treadmill speed up or down. I have to admit these are my favorite training runs, probably since they are the most relaxing from a breathing and heart rate stand point. I can tell my fitness is getting better as I am able to run at fast speeds at my target aerobic heart rate.
Tuesday: 45 min AB, followed by 30 min MSD (Motor Skill Development) with a 6 min down, run on a treadmill. 8 mi, 1:22 of training time. The MSD training is were I run up almost my maximum speed and maintain for 10-15 seconds, at total of a little over 1 minute of running time and then slow to walk until my heart is below 110 bpm and repeat for time of the workout. I do these on a treadmill by starting at 7.0 mph for 12s, then email@example.com mph, firstname.lastname@example.org, email@example.com mph, firstname.lastname@example.org, 9.2, 9.3, & 9.4, and finally email@example.com and the ramping the treadmill down to 3.8 until my heart rate recovers to < 110 bpm. Ending up being 13 intervals for 30 minutes. I find these easier than the mile repeats that I normally do for speed, since the intervals are shorter and I able to recover more.
Wednesday: Rest Day, but I did 32 minutes of strength train. I am older and need it.
Thursday: 30 min AB, followed by 30 min of LT (Lactate Threshold), with 1 mile cool down, run on a treadmill. 7.24 mi, 1:10 of training time. The lactate threshold run should be 10-15 bpm about your AB target heart rate. Based on recent LT workouts on a treadmill I ran the LT part of the run at 7.5 mph. I found this to be hardest workout of the year, and probably should have decreased speed of the treadmill as heart was rising during the LT portion of the run.
Friday: 45 min MSD run with 1 mile warm up and cool down, run on a treadmill. 5.4 mi, 1:05 of training time. 22 intervals for 45 minutes.
Saturday: 45 min AB followed by 29 min LT and 1 mile cool down run outside with my running group's 5 mi group runs at 8 and 9 am. About 5 mi and 43 min for the AB portion, and 5 mi and 43 min for the LT portion. Was able to run with a couple of the faster group runners for the LT run at 9 am.

Sunday: Rest and writing bloop.
This half training plan has been going pretty well this far as I don't have any major aches or pains, but is a lot more challenging than what I have been running lately. I am not sure if I will be able to keep this up, but will take one day at a time, and try to incorporate more sleep.
