What's a hilly ride?

Gosh girls could you have done it metric? I had to do a spreadsheet! and ended up at 85 ft/mile.

Me too.

Why not using "Grade"? That way it is regardless of the unit.
My definition of "hilly" is that the average grade is 8+ % for a distance of 4+ km (2.5+ ml).
After conversion, that's a climb of 422+ feet per mile, for 2.5+ miles.
