Can someone explain the calculation for gradient percent? I figure it has something to do with the length of the slope vs the rise but do not know the calculation.
I was riding up a hill today and someone suggested it was 7%. Just guessing I'd say the road rose about 60-70 feet over a 180-200 foot stretch. It was short but steep, everyone was out of their seat. I have a hard time believeing it was only 7%. Especially when I think about the Giro and they were climbing a 27% grade. If my 7% gradient was truly 7% then pro cyclists can climb walls.
