Years ago when training for the GFNY, over 9000 feet of climbing over 100+ miles there was one guy in my training group who did all the rides on a fixed gear bike, often with weights in a back pack. He said he did because when he got back on his road bike for the event, the hills would be easy. FWIW we were training on sections of the actual route with some of the actual hills.
And if you don't have a long enough hill, just do hill repeats on what you have in progressively higher gearing
