I got a bike recently, and before that I used to walk everywhere. I had classes pretty early in the morning a lot of the time, so i’d skip breakfast pretty often and it was never much of a problem. So today I did the same but rode my bike instead, and it was fine on the ride, but as soon as i got off my heart shot right up my throat and i felt like throwing up. Took like 5 mins of sitting down to feel fine again.
Don’t skip breakfast, kids
That’s probably different from person to person. I have never had that happen to me, and I regularly skip breakfast and have been using my bicycle to go almost everywhere I need to go for the last about ten years. Maybe a better tip would be “If you are bicycling to commute, don’t overdo it on the speed, especially if you are still somewhat new to cycling.”
