Feet per mile is unfamiliar to me. I generally think in terms of overall %. I live in S London and have to cross the N Downs to get to/from my main riding areas in Kent.
1% (~50 ft/mi) is what I get if I don't plan to avoid or seek out hills
1.5% (~80 ft/mi) if I deliberately throw in a few hills.
2% (~100 ft/mi) is just possible but hard to acheive without stupid route planning.
3.5% (~185 ft/mi) is what Ed Laverack managed in his 3,500m 100km ride ... here

and down Mt Ventoux.
