How do you find out the grade of hills you ride? I just don't have a clue what the grades are on hills I ride. So, I define anything that is tough to ride up - you have to shift down, possibly stand up, your HR goes up, and it's just basically a hard effort - as a hill, regardless of grade. There are long ones and short ones, but they're all hills to me.

Very simplistic, I know!
