I think one of the bigger mistakes I made in every previous attempt at running was not having a programmable watchor app to chime off my intervals. Instead, I would look at the time, and then spend the next X minutes agonizingover the slowly increasing seconds ticking toward the end of my run. Terrible.
Contrast that to today: I started off not knowing that my run period had increased, and ran the first one without noticing the difference.
It was a good morning.
