My area, north central Texas, is mostly roller coasters. Not many long flat stretches and no serious continuous climbs. Often the downhills are too short to amount to much of a rest so most rides involve continuous pedaling, with maybe a few opportunities to coast for a few seconds.
To get a good workout involving continuous pedaling effort I have to wait for windy days and deliberately ride into headwinds. It's the only way to approximate the experience of continuous climbing.
On the flip side, the tailwind helps level out the roller coasters to approximate the effect of a long, flat stretch in neutral wind.
