So I went out again this morning with my friend to ride on Coronado island. I bought shoes and clipless pedals yesterday, and yesterday afternoon I did 10 fantastic miles with them. I was very happy, and very confident!
Possibly
too confident.
So we're riding along (I was following my friend) and I was in my zone and didn't pay attention to the fact that I was getting really close to the edge of the pavement. And went right over. The "shoulder" at that point was sand (we're riding along a beach, after all) and iceplant (low-water groundcover that fights erosion). Thankfully the iceplant is spongy, because I couldn't get my foot unclipped fast enough to catch myself. I went riiiiiiiiiiight over, bam. Unfortunately there were half a dozen other walkers/riders around, and everyone saw!

I was fine, I was just kinda irritated with myself. Got up, got dusted off, got back on my bike. Injured dignity.
I tested all my gears, and one is kinda wonky. I'll have to take my bike to the bikeshop tomorrow. So I moved in front of my friend, and then I got this weird panicked idea that
she might fall over, and if I was in front how would I know? So I turned around to look, with my foot still clipped in. This was a mistake. My handlebars are crooked because my arms extend to different lengths because of an old elbow fracture, and when I turned to look behind me I turned the front wheel. You guessed it, I went right over AGAIN!
This time I actually landed on the pavement with my rear end and slid down the edge into the sand on my hands. My bike ended up in the iceplant. I was wedged in, and my friend had to come up and lift my bike off the top of me then help me up. Again people saw...oi, SUCH injured dignity!!
When I fell the second time I just had to sit there and laugh at myself Here I was, so impressed with my bike and my shoes and my riding and my activity level...and I was celebrating by falling on my butt!

I mean, who, after they've learned to ride 25 years earlier, still falls off their bikes on a perfectly flat, straight, smooth road...TWICE??
So I have to confess that I'm not the world's most graceful or coordinated biker. But at least I got out there and did it! And we finished our 20 miles.

And I'll have some lovely bruises!
