I don't fly wingsuits, but from a bit of quick research it seems that 180 MPH is fast even for a wingsuit.
The article itself mentions typical horizontal speeds of around 62 mph.
The Wikipedia article on wingsuit flying says:
> A typical skydiver's terminal velocity in belly to earth orientation ranges from 180 to 225 km/h (110 to 140 mph). A wingsuit can reduce these speeds dramatically. A vertical instantaneous velocity of 40 km/h (25 mph) has been recorded. However the speed at which the body advances forward through the air is still much higher (up to 100 km/h [62 mph]).
Even mentions another jetpowered attempt with hydrogen peroxide rockets reaching a horizontal speed of 160 mph, back in 2007.
