  Recent studies on hypervelocity stars (HVSs) have generated a need to
understand the high velocity limits of binary systems. If runaway binary
systems with high movement speeds well in excess of 200km/s were to exist, it
would have implications on how HVS candidates are selected, and our current
understanding of how they form needs to be reinforced. In this paper, we
explore the possibility that such high velocity runaway binaries (HVRBs) can be
engendered by supernova explosions of the tertiary in close hierarchical triple
systems. We find that such explosions can lead to significant remnant binary
velocities, and demonstrate via constraining the velocity distribution of such
HVRBs that this mechanism can lead to binaries with centre of mass velocities
of 350 km/s or more, relative to the original centre of mass of the progenitor
triple system. This translates into potential observations of binaries with
velocities high enough to escape the Galaxy, once the Galactic rotational
velocity and objects of Large Magellanic Cloud origins are considered.
