W1D2

This morning I finished W1D2 (Week 1, Day 2) and I feel pretty good especially after going all out on my last interval. This is the data from Nike+:

Distance: 2.11 mi
Duration: 29′29″
Pace: 13′56″

This includes a 5 minute warmup and 5 minute cool-down. Nowhere to go but up from here!

The most interesting part of today’s workout was the time of day. I got up at 05:15 and started at 05:40. It looks like civil twilight (a new word I learned, more later) is the domain of cats, homeless people and runners. I was amazed by the amount of cats I saw during my walk/run. Same for the homeless and runners!

I mentioned civil twilight. Twilight is the time before sunrise, called dawn, and the time after sunset, called dusk. Sunlight scattered in the upper atmosphere illuminates the lower atmosphere, and the surface of the Earth is not completely lit or completely dark. The sun itself is not actually visible because it has not yet come over the horizon (sunrise) or it has passed below the horizon (sunset).

Civil Twilight begins in the morning when the center of the Sun is less than 6° below the horizon (the point of civil dawn), and ends at sunrise. Evening civil twilight begins at sunset and ends when the center of the Sun is more than 6° below the horizon (the point of civil dusk).

Cool huh?
