This morning I decided not to try hard riding. I had been feeling rather tired, and all-hard-all-the-time is the fast path to burnout, whether you feel tired or not. So I rode in the local park and worked at staying in Zone 1.
By golly, for most of the ride I did it. It's the first time I managed such a feat. I had to make a conscious effort to stay at a lower cadence, and I stayed in an easy gear. I kept an eye on my cyclocomputer's display screen, so that I'd know when I crept up into Zone 2. The work of getting a drink of water would cause it; and several times I forgot myself and increased the cadence.
There was hardly any wind, which of course was a big help. The weather is still warm, and it's still dry. I don't suppose it will last much longer; after all it's well into October. It's time for a cool front. I'll find out soon enough how well I can stay at Zone 1 while fighting a stiff headwind!
