I group the road intervals together here because they're all very similar, in my opinion, although the variations are aimed to give the runner different benefits.

Or are we heading for a cliff, or already over the edge and simply unaware, like Wile E. Coyote in those old Road Runner cartoons?

We're kind of like Wile E. Coyote plotting a batch of schemes to capture the road runner, only we're trying to catch an entire flock.
