Hey! There are other speeds that are higher than the speed of sound, but still slower than the OP speed of light. Machs!

Mach 1 is somewhere around the speed of sound, as far as I know.

Mach 5 is about 3802 mph.

Mach 10 is about 7160 mph.

I did a bit more research, and apparently, Rainbow Dash's Sonic Rainboom, despite being called a sonic boom, is actually a speed of Mach 10, and not Mach 1 as I thought. This means that Rainbow Dash's top speed is 7160 mph. Basically that means that if she could mantain her tops speed for unlimited time (which she can't), she'd be able to go around the Earth in a bit more than 4 hours. It's still extremely fast, but not nearly as insane as going around the planet seven times in one second.
