25% of the time, solo.
50% of the time, only one partner, and with her, I pull 100% of the time.
25% of the time, 3-5 riders; we all ride about the same.
That puts me in the wind at least 75% of the time, and I like it that way.
It's peaceful, and I don't have to think.

Maybe 150 of the miles above are on bikes made after 1985.
