Quoted message said:All the little thoughts I've been having about warming up are swarming
around in my head and have to be let out.
As I see it there are three distinct types of warm-up:
1. The initial cold-start warmup. The symptoms for me are legs flooding
with that sluggish, dead feeling, sometimes even my arms feel a bit
anerobic

before. It seems to go away after a minute or two.
I always hated this part of the run, but I eventually figured out that if

Quoted message said:upward.
I don't get any discomfort, but I also start out very slow, often walking
for few minutes, then jogging really slow. Starting slow on training runs is
what you described the kenyans doing when you ran with them. I do it to let
the joints and muscles loosen up and to cue the energy systems that things
are starting.

where I don't quite feel smooth and loose, but it's not too bad, unless

feel better. My pace usually picks up about 20 sec/mile.
I think that what's happening here is that the fat-burning pathways are
finally warmed up, giving an assist to the glycogen burning circuits which
take all the load up until this point.
I agree, and I think the transition varies with how fast you start out. A
slower start helps you transition more effectively to higher fat-burning
percentages later in the run, while also perserving glycogen for later. I
usually feel smooth after 30-40 minutes of going slower. If one starts out
fast, they shock the system too much, and then you don't transition as
effectively to a sustainable fat-burning mode. I think I've read that
fat-burning is more efficient with the presence of sufficient glycogen. In
marathons or ultras this becomes crucial.
I believe my race experience Sunday possibly provides a good example of
this. I followed Doug's advice and went very conservatively up the first
climb (3.2 miles 1700'😉, and I felt great the whole race. After that initial
climb I ran at a slightly harder even effort for the next 12 miles (the
steep climbs being somewhat hard to gauge). Then the last 3 miles I turned
it up a notch.
In contrast, what happened to the 80 people I passed? Was I speeding up that
much, or were they slowing down? And if they were slowing down, was it
because they shot all their glycogen early, or possibly because they shocked
their energy systems too much running hard for 3 miles up the first hill? I
would guess it was a combination of these. I think people underestimate the
need for an extended easy warmup to prime the energy systems.
In the tour de France, you see them spinning on the bike trainer for over an
hour prior to the time trial. Obviously this burns some glycogen, but
they've found that it works. A time trial is different from a long endurance
race, but I think the lesson still applies: either do an extended warm up
before racing (up a climb), or go out slow enough to accomplish this while
racing. And it applies to normal runs also.
Quoted message said:3. The uphill-grade-change warmup. Even when fully warmed up (after
20-40
Quoted message said:mins), if the grade gets steeper, my legs will start loading up a bit, my
breathing goes off, and my heartrate actually drops a bit for a couple of
minutes. After this grade-change warm-up has occurred, I feel better, run
stronger, and my heartrate will climb.
I think this is the particular uphill muscle fibres and groups warming up,
similar to the cold-start warmup (but probably should be called a
warm-start
Quoted message said:warmup).
I think you're right, the uphill fibres are being recruited, and are
somewhat anerobic for the first couple of minutes while the aerobic energy
system is redirected there. This might explain a slight initial drop in HR.
If there's less glycogen available (like there was for my climbing legs
starting the climb to Stoppel at mile 12 in my race Sunday) the legs will
feel very heavy and gasp initially until the full aerobic energy system
redirects to them. In my case that took about 10 minutes that day.
Quoted message said:It always surprises me when I encounter a long, steep rise, and feel
crummy
Quoted message said:for a minute or two, that I feel great after 5 minutes, at a higher
heartrate.
When the grade gets less severe, or goes downhill, I just seem to be able
to
Quoted message said:go instantly -- no warm up required when the going gets easier.
Ditto.

Does this ring true to anyone out there? Or do I have way too much time
on
Quoted message said:my hands?
Rings true for me, and yes 🙂 but I think point 2 is important to
understand.
