I wear a mask while riding, but I’m doing so in Manhattan, where there’s always people around, be it in traffic or stopped at an intersection. I’ve ended up doing shorter rides at less effort this year, partially due to mask discomfort. If I were able to go outside and not see people, I probably wouldn’t mask up for the whole ride. I also stay away from the heavily trafficked paths when there’re lots of cyclists - difficult to stay 40ft (or more) back.
Here’s hoping the latter half of 2021 will be better.
