I was simply out of fuel. It wasn’t the hot weather or humidity. My tank was empty. I was inadequately prepared for the ride I had planned. Once I took in some calories and carbs, I was ready to roll.
I have stopped for a coffee after completing my usual 40 km Thursday workout. The way I was feeling, I thought I was done for the day. But no. I simply had to stop and gas up. Go figure.
I have never experienced this before. I always been able able to ride for an hour or two, even if I was unable to fuel up. I am generally better prepared. I usually have energy snacks on board just in case.
If anything, my reserves are low. I need to eat more or ride less.
