I am trying to build a running base by trying LSD using a heart rate monitor. At a leasurely 5
mph, my heart rate starts at 133 bpm and gradually climbs to 166 bpm after 1 hr. At 45 years young
my 85% tempo heart rate should be 167 bpm according to Runners World.
In order to keep my heart rate at 145 bpm after 1 hr, I would have to drop my speed to 4 mph?!
Does this seem normal? I can't imagine how to keep my heart rate down.
Unfortunately, HR does not merely measure your running effort, but also relates to your body's
cooling. Your heart is not only pumping blood & oxygen to your working muscles, but is also working
to cool you off. As your run progresses, you get hotter, and your HR reflects the extra-cooling work
your heart is doing. This is sometimes called "heart rate creep." Personally, I allow myself 10-15
beats of creep.
You should also keep in mind that the formulas for max heart rates and percentages thereof are not
likely to apply to you. To know your true max heart rate, you must be tested. One final point: I
don't buy the "run at a low HR to get faster" argument. I tried it for about 6 months, and I just
stayed nice and slow. Lately, I'm just letting my body run at the rate at which it feels
comfortable, and use my HR monitor as a safety check only. YMMV.
