Come early January, increasing daylight is quite noticeable but what always surprises me is how much this contrasts with a few days ago in late December when we were lurching headlong into endless darkness. Just before seeming inevitable it would become depressingly gloomy, brightness now hints through wintery skies. I probably sense it more at this time of year because my morning commute is at dawn when the change is happening. Cycling at any time of year heightens riders' senses to seasonal change. For me, this is one of the plusses of riding at dawn and dusk.
