the headwind ride that sticks in my mind the most was new year's day this year..... i have this one route that is rolly... but mostly up on the way out.... i was FLYING up the hills... but then.... i had a 25-30 mph (or more... forget now) tail wind! then i turned around..... i was actually using my baby (granny) gear to pedal DOWN the hills! it was AWFUL!!!!!!!!!!!!
i always slow down in a head wind.... and i particularly hate when i have the strong (20-25 mph) headwinds when climbing!!! it's bad enough on a flat... but add it to a hill... UGH!
