Today was the first bike commute of the year, a leisurely one on a grey day (where by 'leisurely' I mean that I mostly stayed under 20 km/h). I almost made it the first bike commute of the year in sandals, but I decided to save that for tomorrow, when it will be up to 10C instead of this morning's 1C.
(It will also probably be raining, but that's what I have waterproof shoe covers for.)
