Look, I'm not some great natural athlete, and at 48 years old, I'm not sure that my sense of balance is what it used to be. So I was pretty nervous about getting my first set of rollers.
I went with Kreitler Challengers, and I just got off the bike after my first half hour on them. I'm pretty proud of myself! I didn't injure my self, my bike, or my living room, my wife didn't divorce me, and I managed to put together a few five-minute unsupported runs.
It's not often you can pick up a new physical skill beyond a certain age, and it feels great!
