  1. Now that I have started keeping a daily log, I have added a
    total daily Effort/Calories column.

    EffortCalories=(MilesRun*100)+(MetersSwam/300*60)+(Km-
    Cycled*30)

    Ok this is rough, I realise the above contstants are
    variants depending on speed and my size, but do these
    constants seem reasonable?

    And can this information be usefull for anything?
    overtraining?

  2. Sounds about right to me, although I would have guessed
    maybe 25 instead of 30 per km cycling. I also think the
    swimming calories could vary a lot more than the others
    based on individual factors.

  3. I would say no, since the formula does not take intensity
    into account. Also, since enviromental factors come into
    play (headwind \ tailwind), you can't really assign a
    constant caloric expenditure. Instead, you could use your
    heart rate monitor to get a rough idea. For example, basal
    metabolic rate is about 1 Cal / min (3.5 ml/kg/min). So a
    rough range would be: A VO2 max of 70 ml/kg/min indicates an
    energy expenditure 20 times greater than that at rest, at
    max heart rate. This works out to 20 Cal/min. With these
    numbers (assuming you know your approximate VO2 max \ max
    heart rate in each sport, you could get more valid numbers.
    You then can divide your paces into zones.

    Here's a rough idea of VO2 max values:

    1. Joe Fatass: 45 ml/kg/min
    2. Recreational: 55 ml/kg/min
    3. Serious Age grouper: 65 ml/kg/min
    4. Pro: 75 ml/kg/min

    So, if you're recreational:

    5. easy: 65% x 55 ml = 35 ml / 3.5 ml = 10 Cal / min
    6. moderate : 75 % x 55 ml = 41 ml / 3.5 ml = 12 Cal / min
    7. hard: 85% x 55 ml = 46 ml / 3.5 ml = 13 Cal min

    Note corresponding heart rates for the above. Typical
    numbers for 30 year old would be around:

    8. 140 bpm
    9. 160 bpm
    10. 180 bpm

    I suppose I am Mr Recreational guy, (43y.o. 6'1" 80Kg),
    don't have any idea about my HR or VO2 max. I perform with
    mostly a constant effort in all 3 sports, so without getting
    too involved I am hoping that using a constant for each can
    provide some usefull info. (ie total effort for the day and
    for the previous x days)

    I am just getting back into the running after a long layoff
    currently at 20+mpw, would like to get this to 25+ mpw and
    improve my current
    v.slow speed of 9:30mpm, I commute to work on bike 50km-
    150km/week (anything above 50km are forest trails so
    probably requires a higher calorie/km), I swim 4-6km per
    week at steady 1:45/100m.

    I pretty much base each session (speed and distance) on how
    I feel, but in the past without a log I have overdone it.
    With a log I am hoping I can spot when I have already made
    an advance in effort over the previous x days (my log shows
    me each day the total for the previous 7 days), and perhaps
    it should be wise to hold back a bit for a day or two, or
    more, before making further advances.

    I am already seeing a benefit in keeping a log over the past
    8 weeks with the progression of my running.

  5. I utilize my heart rate monitor to help me gauge how much
    I'm working. My Polar has a calorie reading as well (which
    is mostly just entertainment - I don't really use it for
    anything other than curiousity).

    I also use the HRM to help me determine if I'm over training
    (typically with me I notice an increase in my heart rate
    over my typical levels for a typical intensity level). For
    example, when I run easy my heart rate is 140 - 150. When
    I'm getting sick, over training, etc same intensity level my
    heart rate will be 150 - 160.

    A heart rate monitor is just a good tool to utilize in
    your training.

    I would continue with the log (its another visual reminder
    of how much you are training).
