There aren’t any in theory, but there absolutely is a limit in practice. Beyond a certain point if you’re caught you will be arrested and surely convicted for reckless endangerment. And how do you plan to get up to that speed? If you’re going to use something with motorised assistance, it will almost certainly be a device that the State will class as a road vehicle. Driving on the sidewalk is illegal.

Any "limit in practice" is not a prescribed limit. The whole point of posted, visible speed limits is that everyone knows what they are ahead of time. They're not a substitute for using your brain. (Also in practice if you go too fast you'll run up against physics and literally burn up due to atmospheric drag.) > And how do you plan to get up to that speed? OP's example is a world-class track sprinter. Usain Bolt just runs fast (for 100-400m). In my state, non-motorized bicycles may use the sidewalk freely. When riding on the sidewalk, cyclists are considered pedestrians. They (like all other pedestrians) must be courteous to other pedestrians, but there is no speed limit. In theory, on a long enough sidewalk without ramps, alleys, obstructions, etc, a cyclist could plausibly exceed 30 mph without being discourteous to anyone or endangering others. There are some sidewalks like this in the industrial parts of my town, although I'm certainly not suggesting anyone try it.

Obviously there isn't a prescribed limit. That doesn't elide the point—a limit doesn't need to be a bright line in order to exist in practice.
