I was wondering, how you find the % grade of the roads you ride?
Is it published on a bicycle map?
Do you calculate an average using distance and elevation on topo maps?
Do you calculate it using a cyclocomputer and a GPS?
Do you look at the hill and guess? (my current method)
Is there some other device, bike mounted or handheld, for finding the slope of a hill?
I have been wanting to find the grade some of the hills I ride. I have something I use for finding the slope of ramps and roofs on buildings, but I don't want to carry it around, stop, get off the bike mid-climb or mid-descent and measure.
How do YOU find the % grade.
