speed relates directly to heart rate.
I guess the final question is... Even if I am shooting for
a specific pace, my heart rate will tell me how much my
body is ready to do at any one time... which implies that
training for pace is silly.
uh.... right?
It depends on the distance of race you're training for, and
if you will race on relatively flat roads or hilly roads or
trails. If you want to run fast in road races you probably
want to learn both pace and HR response to those paces,
mostly for training your lactate threshold HR (LTHR). For
most training I use HR to make sure the effort is aerobic.
For speedwork and racing, I would want to know my current
lactate threshold HR and what paces I can run around that in
order to train the the lacate system. Thus in shorter races
(10k and under), you will want to know the pace you can
sustain for the race and measure your performance each mile.
For trail races and ultramarathons (and probably marathons
for most people), using HR as a gague of effort makes much
more sense. You can learn what HR you can hold for x number
of hours, both in training and in racing. For me this looks
like this:
resting HR 42, maxHR 190, LTHR 175
5k ~20 mins HR 180 (15%? anaerobic) 10k ~42 mins HR 178
(some anaerobic) orienteering 90 mins HR 173 (over one
hour, <LTHR) 50k trail ~6+ hours HR 158 (substantially less
than LTHR)
For Shorter races on flat roads its better to use pace
because HR is harder to read for effort. On longer efforts
watching HR becomes critical.
For training I keep aerobic as much as possible (HR 135-
150), and for speedwork I try to train just above my current
LTHR. For example my LTHR right now is about 168, and closer
to 175 when im peaking. The other day I did two 10 mins
intervals of HR 172 (felt like 10 race pace) and HR 176
(felt like 5k race pace), with 5 min rest in between. If I
were going to race at 5k or 10k then I would measure my pace
during these intervals to start to set a specific time goal
for the race. But my goal is a trail race so I don't care
what the pace is, only the effort, and traing the lactate
system will improve my speed at any distance because it will
help prevent acid damage to the muscles.
