11,680 furlongs per fortnight is about one-fifty-fifth as fast as a Peregrine Falcon
In other words, the speed of a Peregrine Falcon is 55.60 times that amount.
(a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)
The Peregrine Falcon can reach speeds of up to 650,000 furlongs per fortnight when diving. Falcons are sometimes sent to scare smaller birds away from airports to improve air traffic safety and were used in World War II to intercept carrier pigeons used by enemy forces.
