Lydiard/Heart Rate question

1/4 effort – easier, but still aerobic pace (not jogging), 65-70% of (Maximum minus resting heart rate). For example, with a resting of 55 and max of 195, it works out to 145 to 153 beats per minute. For one runner it could be approximately 7:25 to 7:50 per mile depending on how he feels and the conditions and if it is early in base building phase or late in the base building phase.

1/2 effort – run at a strong aerobic, but sub tempo pace, 70-75% of (Maximum minus resting heart rate). For example 153 to 160 beats per minute. For our example runner that could be 6:40 to 7:10 per mile depending on how he feels and the conditions and if it is early in base building phase or late in the base building phase.

3/4 effort – run at tempo pace/At Threshold (AT) pace, 75-85% of (Maximum minus resting heart rate). For example 160 to 174 beats per minute. For our example runner that could be 6:15 to 6:35 per mile depending on how he feels and the conditions and if it is early in base building phase or late in the base building phase.

WTF????

Skip Molvar.

It should be max HR-resting HR* whatever percentage + RESTING HR. ex MHR 190- Resting 45=145*70%= 101.5+resting HR (45) = 141.5.

If you're thinkin' heart rate you're not thinkin' Lydiard. Any explanation of his approach that talks about heartrates would never get his seal of approval.

I agree. HR is affected by many other factors than just running intensity. If it's hot, you're dehydrated, fatigued, etc., then HR will be higher. An example is if your LT is 5:20. Suppose it's 90 degrees. Well you ain't gonna run a 5 mile tempo run in 5:20. You'll be overheated and if you use HR, then you will likely hit LT HR at about 5:40 pace. Guess what? Your body doesn't care, you're not at LT. It's at 5:20 regardless of the temp. I think in good conditions it can be used, but it's not an absolute.

sorry, maybe because i've been doing HW all day and my brain isn't thinking clearly, does LT mean lactate threshold?

Sorry, yes.

LT = lactate threshold

HR = heart rate
