It used to be that cold weather didn't bother me too much. Increasingly though I find that it's harder to hit a rhythm running when it's below 20 F. Must be a symptom of old age (today is my birthday!). My remedy is to wait for warmer temps. Rather than run Saturday, I volunteered to Stephen that we wait until today, thinking it couldn't get colder than it was Saturday. It might have paid off...
