I love this time of year. The air is crisp and fresh and the days are getting longer (by about 3 minutes per day apparently). Now that I am cycling to work at the same time every day this is especially noticeable. Roads that were pitch black a couple of weeks ago are now just murky; and country lanes that were murky are now lit up by the rising or setting sun.
We are currently enjoying about 10 hours of daylight per day in the UK which is a vast improvement on the 8 hours we had in the depths of winter. Being able to properly see my way on the bike is more enjoyable than trying to make sense of the shadows and silhouettes approaching me along the country lanes.
