You know you've bonked when...

So I've been feeling intermittently sick and drained lately. Instead of my normal commute of ~16 miles, I've been using the bus and cutting it to 5, or no cycling at all.

Well, I forgot to buy a new bus pass, so did the entire 16 miles on the bike today, ~15-18mph headwind. Making a left turn. Didn't turn enough. Instead of correcting I...put my feet down and try to brake/slow down/pivot that way. No go. The thought of taking my hands off the tops, and reaching for the brakes somehow never appeared in my head. Instead, I just get ready to bail after the inevitable contact with the curb.

I did a fine job of bailing though, completely cleared the extra wide sidewalk to land in wet mulch. Not even a bruise.

That's not bonking. It's zoning out.

Bonking is simply when your blood sugar level drops too low. Like if you go into a hypoglycemic state. It happens when you don't eat. You can bonk sitting at your desk doing nothing if you didn't eat all day ... and you'll bonk quicker if you're active without eating.

If you did the 16 mile ride with no breakfast, and very little to eat the night before, you might have bonked, and you would have started experiencing symptoms such as:

Confusion
Lack of concentration/behaviour change
Dizziness
Light-headedness
Feeling shaky
Hunger
Headaches
Irritability
Pounding heart; racing pulse
Pale skin
Sweating
Trembling
Weakness
Anxiety
Tearful/crying

Those are all symptoms of the early stages of a bonk. If you start experiencing those symptoms, it's a good idea to stop and eat something.

i've bonked commuting. you have to take care of yourself more and eat more. my advice is don't eat lots of sugar or caffeine, try oatmeal. its a slow digesting sugar that doesn't give you the sudden high imbalance.

I actually am a diagnosed hypoglycemic. I had a snack stop a about half a mile before, it just hadn't taken effect yet. I keep two emergency bags on my bike, 1 for tools&tubes, 1 for edibles. In hindsight I should've just hung out in the shade for 20 minutes, instead of just chowing and pedaling immediately afterwards.

the symptoms are, for me when cycling, an overwhelming conviction that my rear tire is going flat and even a slight downhill is actually uphill. oh... and every wind is a headwind.

Best example I've heard here was the guy who saw a discarded, half-eaten donut in the ditch.
He picked it up and wolfed it down w/o hesitation.

And your bike suddenly feels extremely heavy, like it is made from Iron.

I usually do dumb things... Like turn in front of bus, or ride off curb...

My SO and riding partner, she'll stop talking, then get serious, start weaving (usually she rides a marvelous line), then falls over or fails to unclip..

Couple nights ago she did a left as yellow went to red, almost got hit, and cop pulled us over... She was unusually testy. He still let us off...

Taking a break and cooling off for a little while.... solves more problems than most of us ever realize.
