For easy run, it seems 65% HR a bit low. Say, if your max HR is 180, 65% of that is 117 - seems too low to me. I would think 70-75% be better, No?
When I am in sub 3 marathon shape, my HR is about 130-135 with 8'30" pace run, so roughly 70%, with a max of 185-190. To get HR to sub 120, I would need to slow down to 9-9'15ish - that seems too slow for a sub 3 marathoner.
Hadd actually says it should be 70-75% of max. In the example he gives, the guys max is 193 and so he set his easy days at a max HR of 145 (75%), or lower. It should also be noted that as you build your mileage, you can add a little intensity. In the example, Hadd shows the runner doing 2 runs per week at 145 HR, 2 runs at 160 ("tempo"), the long run at 155, and the last 2 runs at a 150. He also sometimes has the long run include time at 160 as well (up to an hour)
The idea is that the two tempos start a bit higher, for the example, he has "Joe" start with the "tempos" being between 155-160 (10-15 bmp higher than your easy days should be good), with the goal being to get these up to 175, which was his goal marathon HR (15-20 beats below max). So he might start off with 3x15 mins at HR of 155-160, then 2x25, 3x20 etc until you can do 75 mins or 10 miles at this HR, still feel good and the HR should stay even at 160 the whole time, it shouldn't drift near the end but still average 160, that doesn't count. Once you can do this, you up it by 5 bpm, so now you try to do the same thing with 165 bpm and so on until you hit your target marathon HR for 10 miles (or 75 mins, whichever comes first). It will take a while to move this up, in the example, Joe took 12 weeks to move from 160 to starting 170.
Hadd also does add some workouts every once in a while. After 8 weeks, he introduced a 200/200 fartlek, where you run 200 meters at 5k pace, then 200 meters at 5k +12-15 secs, do this for 10k total.
Below is the summary at the end of the Hadd, document, but I strongly suggest anyone read the document in full (it's not that long) if they are interested in using it.
If your HRmax is 193 OR HIGHER, then the following applies:
HRmax: 193+ (even if over 200)
Best possible HRmarathon: 175-177 HRav (note, this is the average taken from mile 5 to mile
25, not the peak. Your HR might peak to 181 in the final miles as you throw everything onto the
fire).
Suggested training HR's: Easy every day running: 145 HR or lower (If you begin really unused
to this form of training, initially you might start at 150, but as soon as the pace at this HR
improves, it is recommended that you reduce your easy running HR to 145 or lower). This can
often feel very slow to begin with, but should improve within 3-6 weeks and continue to improve
for months. You may do as much running as you wish at this HR/intensity (always being careful
to avoid overuse injury).
Initial LTHR (initial lactate threshold heart rate): As with Joe in the example, begin at 155-160
and do not let the HR rise on the run. Build up the distance you can run for, over time, to 10
miles. At first, you may have to slow down within the run to maintain HR, but over the weeks
and months, you should note that the running speed begins to remain more stable and you do not
have to slow down (so much) to stop your HR rising. In time, the running pace at this HR (and
all other HR’s above it) will also improve. Only move this HR up when your running pace vs HR
is rock steady and you (easily) are able to run 10 miles at this HR without loss of pace or rise in
HR. At that point, only move the HR up by 5bpm and begin again. The slower you build up the
first time, the better your pace at HRmarathon will be. Remain at each HR as long as you are
seeing improvement on the 2400m test and definitely until your pace vs HR is stable. You are
trying to reach a state where your predicted/expected marathon pace and your 170 HR pretty
much coincide in the 2400m test. And that this pace per mile can be maintained in training for
10-15 miles at 170-175 HR without rising effort or rising HR.
For example training weeks (60, 70, even 80+ mpw), go back to Part V (B) and plug your
numbers into the example weeks given for Joe's training. (Want to run more mileage? Add in
some extra miles at 140-150 HR. This can be as doubles on some days, up to 8miles in the
morning and 10 miles at night. All easy aerobic running.)
Rid yourself of any sign of impatience and just knuckle down to the work. Remember, a
constantly dripping source of water will eventually erode solid rock. For this to work, you need
your muscles to change, and change takes time. Mitochondrial growth takes ~6 weeks. So look
for small change every 3 weeks or so, and significant change every 6 weeks or so. It is not
suggested you 2400m test more regularly than every 6 weeks. More often is just frustrating, like
someone who is trying to lose weight, jumping on the scales every morning hoping to see the
pounds drop off. Just do the work and give it time to have an effect. Farmers don’t pull up their
potatoes every five minutes to see if they are growing…
