Be glad you can get out in the sunshine. On my commute, I've not seen sunshine for months!

When I get out for weekend rides, I love feeling the sun on my arms and face and the fresh air in my lungs. I also employ the method of playing games on my route, such as seeing what speed I can carry up known climbs, standing sprint intervals, sitting time trial practice on flat sections, that sort of thing.

Worth a shot, I'd say.
