Dad and I have been going out every morning to ride our bikes since Sunday.
We started going out more often because a really nice bike path, wide and smooth, was recently made.
There's this long section with no stops, slightly sloped because it goes along the river. We call it the Bicibahn, named after the Autobahn in Germany.
On the way back down the bike path, I normally draft off Dad. If I can keep up with him, he'll "torque out". He has a mirror on his helmet, so he can see how I'm doing.
Early in the week, it was a little scary, but now it's fun and exciting.
Most of the time, I have to mouth-breathe to keep up with him. Sometimes I'll even get little pebbles in my mouth, thrown up by his tire.
Anyway, this morning, I was struggling to keep up with him when I thought, "I wonder how fast we're going?" I was in my top gear, and pedaling at 100-120 RPM. I was close to out-spinning my top gear.
