At first, it was. Now, it just feels like I have no strength in my usually strong legs and awkward, hence the feeling I'm going to crash.
But, you're right, Mimi. I am no slouch when it comes to climbing; in fact there have been several times on group rides where the guys (OK, older guys) ask me what kind of training I did to be able to spin up a hill at such a high cadence. The answer is always the same. No training, it seemed like the natural thing for me to do.
I just wish I could stand with as much ease.
