Overdoing the Exercise

Last night I got home from work & was in two minds whether to fix my MTB & go out for a ride, or to just go on the exercise bike. I figured the better workout would be the exercise bike and duly got changed and did 8.5 miles at a fairly constant 20.5mph. A good sweat was built up but fortunately the weather has cooled down some since last week although it was still a punishing pedal for me. I thought at some point this was supposed to get easier?

On getting off the bike I found my knees both felt kind of wobbly and throbbed a bit which was unusual, but duly jumped...well walked...in the shower. On turning off the shower and getting dry I suddenly felt very weak, shakey, sweaty hot and kind of ill - exactly the kind of way I feel when my blood sugar levels get dangerously low. Its at these times you must get something sugary inside you ASAP and I called for my wife to see if she could get me something. My first thought was a chocolate biscuit, which isnt a good sugar suppliment because it actually releases into your blood stream very slowly (chocolate isn't a problem for diabetics to eat hence why so called Diabetic Chocolate is a total waste of money). However it was better than nothing and served to at least get me a little energy to get dry and dressed.

I have to say that I then wolfed down my plate of Chili Con Carne, side salad & pitta bread like an animal. It wasnt until nearly half way through the meal that I completely stopped shaking and felt better.

So a lesson has been learned there, or rather a lesson has been re-learned. Its happened a half dozen times before, although not for a long time, and even though its always in the back of my mind, I only carry something to eat if Im out & about for a long time. Quite possibly if I had only gone for a proper bike ride last night my sugar level wouldnt have got so low, but I wouldnt have had anything with me to eat if it had, and I wouldnt have been near a shop either. These things can come on so damned quick its like you're fine and then literally 10 seconds later its full on sweats, shakes & you feel like you're going to pass out - which eventually you would.

However, I managed to scratch off another one of my goals which was to do a cumulative total of 70 miles on the exercise bike. I'm really glad I made these exercise bike mileage goals in 10 mile spans because its an incentive to get on and scratch off another goal if its close.

  1. At the end of your turbo training session if you warm down slowly by spending 5/10min pedalling very easily and drinking loads of water until your heart-rate falls to normal you should avoid the 'Bambi' legs.

    Pulling your sweaty shirt off and sticking a warm jumper on helps avoid the hot flushes.

  2. I generally ease off the gas for the last mile / half mile but I'll try the other things too. Thanks.
