My dad always said when I complained about Chicago wind: "doesn't matter, the wind is usually against you on a bike!" Meaning I still had to get myself home, he wasn't always available to come rescue me.
Good job on covering the distance, dealing with the wind, getting home under your own power, and finding a way to cope with flat bar hand position challenges!
One thing I found a few years ago when trying to work up to longer distances, is that if my butt can handle the distance, my legs and the rest are not far behind.
I just did my first reasonably comfortable 23 mile ride of this season, so I'm pleased, especially since last year was nearly a lost season. Next weekend I have a scheduled, organized ride. I'd hoped to do 60, but right now I'm happy to predict I can do one of the planned distances! Small but significant achievements.
Again, congratulations!
