April 4: Stomach upset overnight and into morning, took the day off so I didn't commute to work. I was fine by the afternoon so in the evening, I went for a 8 km ride. Very cool again, and with winds too, -8C/18F but feels like -14C/7F. However, by about 1/2 way through the ride, I felt much better although still cool for the rest of the ride, just not freezing.
