That was a trend with me for a while, then I made my peace with it. You can't fight nature by being mad at it.

On a serious note I read somewhere that the negative effects of a headwind are actually almost the same for a crosswind. There is only a narrow 30 degree range centered directly behind you in which you get any benefit from the wind. Outside that 30 degree range the wind starts to be a hindrance. Maybe that's why it feels like the tailwind doesn't happen as often as the headwind.

I love being in shape and going 15 mph into thick wind without getting cooked.

thats when you turn your torso to get more wind into your back.

+1. Wind and hills are easier if you like them.

Being up front with a strong headwind is fine as long as its not a hammerfest. Otherwise, short pull and try to position behind the "big guy". Being up front with a strong tailwind is the shizzzz.

any time I start feeling strong on the bike, I think "oh -- tailwind." Doesn't happen very often.

Like others, I think the red slice in the second chart is a little too large.

I have similar results for uphill as opposed to down hill

I honestly believe that M. C. Ecsher laid out my training loops!

i'm actually getting to that point, but the fact that i don't get as frustrated with a headwind doesn't mean i don't still feel like i'm always riding into one.

it's gusting 40mph today...i might have to get out in it to do some hill simulation training

I am starting to embrace "the suck" with the wind. Not much I can do about it, so I might as well enjoy it.

Exactly, I'm riding along and thinking Lance...watch out. Then I turn and hit 11 mph going downhill. Humbling.

I like that!

I'd like to see video proof of this tailwind. I've never seen such a thing.

Two rules about headwinds:

1) If it lets up enough for you to upshift, the headwind will increase to >+5 mph over the original windspeed;

2) If said upshift includes going from small to big chainring, it'll increase to >+10 mph over the original windspeed.
