  1. Today on the commute home, I was heading at a fair speed down a slope on the
    fixie, pushing a little to try to stay ahead of the cars as I approached a
    roundabout. The computer said 49.9kmh max, which is about 150RPM on my 67
    inch gear (46X18 on 700x23). This is the fastest I've been on the fixie -
    felt like about my max unless I get shorter cranks.

    Halfway down I got a cramp in my left calf. Being fixed, there are not too
    many options available. I stopped pushing and kept turning over the pedals.
    This was bearable at first, but the pain got worse and worse. Eventually I
    unclipped and rolled to a stop one legged. I am so glad I have a front
    brake.

    I had not drank anything on the ride, but I was not even at the 20KM mark.
    So my questions are: what should I do to avoid this in future and what do I
    do now that I am home with pain in my calf, but no cramp?

    My completely uneducated recommendations... more fluids, more bananas, and
    more stretching pre and post ride...

    There's my problem: I only stretched my right leg as I swung it over to get
    on the bike. And the cramp was on the left. Pretty [censored] poor stretching
    routine I'm afraid.

    routine I'm afraid.

    The body already gets enough stretching of muscles from normal activities
    for bike riding, except for when you've been holding a position for too
    long then it is advantageous to do 'on the bike' stretching of the quads,
    or rotating the neck or back. IOW, normally you don't need to do prolonged
    stretching like a gymnast, ime.

    You should probably now do the routine R-I-C-E and take NSAIDs every four
    hours. Sounds like you might have a bit of an internal bruising.

    If you do need to do some stretching, I'd advise only post-ride stretching
    while you are still warm and sweating from riding, and then only gently, no
    bouncing.

    In my background, I've done a fair amount of stretching pre and post to be
    able to do full splits and touch chin to toe with straight leg, but this
    was for martial arts. Cycling doesn't really require such extreme positions
    unless you're very unlimber.

    Good luck!

  6. May not be relevant to you, but I have had leg cramps at various times, and
    for me it is due to a magnesium deficiency. I pop a magnesium tablet each
    day for a couple of days and all is well again.

    We get some replacement electrolytes as part of our normal diet - sodium
    from salt, potassium from bananas, chocolate.

    But constant sweating will tend to exacerbate the problem that Aust water
    tends to be deficient in magnesium, and that deficiency is often the problem
    in high milage cyclists. Blackmores do a product called MagMin (any vitamin
    retailer will know of it) which is ok - there is an industrial strength
    magnesium supplement intended for horses which I am told is even more
    effective but I don't know its trade name.

    Most in my bunch who have had the problem report reasonably quick results
    with Mg supplements, assuming problem is not a result of poor position or
    similar.

    Hope that fixes it - best, Andrew

    Interesting about the water being Magnesium deficient. If I could be
    bothered I would actually find out which foods are a good source of
    Magnesium (Google is my friend!!).
    I use the Blackmores Bio Magnesium. They have a cheaper magnesium
    supplement but didn't find it to be as effective.
    I normally have cramping problems when I have been doing high mileage and
    sweating heaps. During summer I tend to have 3 or 4 Mg tablets a week for
    Justin (case). I also think I used to exacerbate the problem by drinking
    coffee and thus peeing more, but I have managed to almost wean myself off
    the caffiene now, and feeling much better for it (better quality sleep).

    All my drinking water comes off my roof. I have no Gov't utility pipes
    connected to my house. Should I have installed magnesium gutters and
    downpipes?

    Bananas are cheaper and have the added bonus of energy.
