It was almost 90 degrees as I rode home against a 25 mph south wind yesterday afternoon. This morning, it was 52 degrees as I rode to work against a north wind gusting to 30 mph. It took me over an hour to pedal the 12 miles to work, and my 10.8 mph average for the ride is my slowest ever in the two years I've been commuting by bike. I'm looking forward to a good tailwind on the ride home this afternoon.
