    In response to Sam's recent posting on "Hadd training", I decided it would
    be fun/interesting to test myself. So off I went to the track with a heart
    rate monitor, following a similar testing protocol. In the interests of
    brevity, I did "only" 4 laps at each heart rate, starting at 140, then going

    Don't you think it makes a big difference of doing this test fot 1 mile
    instead of 2.4km ie. 6 laps.
    YMMV but as for me, with such short distances, I don't get the same
    avgHR if I run 4 laps or 6 laps.
    But you may have had another goal by doing so.

    What I understood from the "Hadd training" lore, (that Anthony kindly
    pointed to me), is that for marathon training, there is no need to do
    speed sessions, only to build a strong aerobic base, slowly @ 70% MHR,
    and do some faster runs @ 85% MHR for 10miles.
    This will steadily rise one's LT.
    The value you get @ HR:170 (MHR ~ 193, ie. 88%) in the test you did is
    supposed to be the pace you'll sustain for the marathon...
    One is supposed to repeat the test every 6 weeks, the time required for
    mitochondrial growth (says Hadd), hence higher LT.
    Does this fit with your marathon pace ? (I remember you talking about
    maybe running a marathon, but I don't recall you did)

    to 150, 160, 170, 180. Which worked reasonably well. It was easy to get it
    right at the lower paces (140,150), harder to hit exactly the right HR numbers
    at 170 and 180. So I recorded:

    HR time
    140 8:42
    150 7:45
    160 7:10
    173 6:24
    183 5:52

    Plotting pace (that is, 1/t) against heart rate, I was surprised how good a
    fit the linear model gave me -- R^2 = 0.9981. Basically a perfect straight
    line.

    anyway it sounds interesting, and I'll probably try it myself... if not
    the whole training, at least the test!

    I thought it might before I did the test, but I found it stabilised awfully
    quickly, e.g. after 200m or so. I did these continuously, no break in between,

    ok, because he also advises to stop for 90secs after each 2400m!

    Quoted message said:

    I didn't record average heart rate. The heart rate I recorded was what it
    settled on after about 200m. After the first 200m, I have a pretty good idea
    how fast I need to run, so maybe the first 200 is off by a couple of seconds
    but the rest is OK.

    If you didn't stop between the different sections, I can indeed
    understand that your HR did stabilize itself in about 200m!

    Quoted message said:

    Mostly time -- it's 2.5 miles to and from the track, and I already had to do 5
    miles to finish the protocol with only 4 laps.

    yes I can understand this point!

    Quoted message said:

    I ran a marathon, but it was in warm conditions, and I was in better shape. So
    not sure what these results would say about that. I've never done the test
    while in good shape.

    but was your AVG HR at about 88% HRM?

    Quoted message said:

    Sounds good. Post the data so we can look at it -- I'm curious if the model
    will fit as well with your data as it did with mine, and if there's any sort
    of plateau in heart rate (as Steve Common suggested)

    I'll try it next week, because as you say, it's a pretty long session,
    and I wouldn't want it to interfere with my training for this upcoming
    sunday's 10k

    yeah, not sure if there's a good reason for that. The reason Hadd uses the break
    is because it's a lactate testing protocol -- usually he draws blood. He
    probably wanted "Joe" to use exactly that protocol because he was familiar with
    it.

    The only thing I'd be worried about by omitting the stops is cardiac drift
    (though also making the protocol shorter would help). In my case at least,
    that just didn't happen. Like "Joe", I got a perfect line. Should be noted that
    the "Joe" data also fits a line very well, about the same goodness of fit as my
    own data.

    Not sure what you're asking. My max is about 195.

    Butting in here, I think he was asking because in the training example, Hadd
    worked backwards from the knowledge that Joe's marathon HR should be 174-176
    for his max HR of 193. Based on the track test Hadd saw that Joe's current
    level at 170 (non-race equivalent of the race-drifted 175) was too slow and
    Joe was showing signs of being over LT at that effort level. Hadd then set
    Joe's long-tempo training pace at 160.

    I see. My HR 173 pace was 6:24/mile in the test. There is no way I'm in
    6:24/mile marathon shape right now. Another issue with marathon pace is that
    you've got to make some allowances for the course and conditions. I did the
    Hadd test on a track in cool conditions, but if I were to do the same test
    running over a marathon test in warm weather, I'd be slower. I did my 18 mile
    run yesterday in very warm conditions (just over 80). I stayed arund 150 for
    the first 12 miles, and I ran those at about 8:30/mile (same as my 140 pace on
    track test). The last 6 I ran at about 8:00, and HR was often in the low 170s.
    I take that as a sign I'd be pretty damn slow in a marathon under those
    conditions right now.

    It will be interesting to see how the test readings change as I get in better
    shape though. Once I can get through long runs at around 7:30/mile in warm
    conditions (that's the sort of shape I was in during last years summer
    training), we'll see what the sub max says.

    thank you tony, that was indeed my point ;-)

    I've got an inkling that if I run the test, I would also get a pace too
    fast to be sustained in a marathon @ 88% HRmax. (which is just the
    opposite of what Joe got!)
    This would only show, I suppose, that with my current 10k training with
    30miles weeks, I'm simply not ready to run distances over a HM, and that
    I need to work on my LT...

    indeed, I'll try to do the same!
