I didn't feel like riding, but I made myself head out into the wind today--half gravel, half asphalt. I noticed my forward progress was slow. Checked the speedometer, and saw 4 mph. I hit 33 on the downwind return. That moment of speed made the upwind ride worth the effort.
My 13 year old daughter just arrived home from school excited. She said she didn't even have to pedal, the wind pushed her home.
