SCP-2872 is a thoroughbred stallion of indeterminate origin and pedigree, with a height of 1.85m and a mass of 485 kilograms. It is an exceptionally skilled racehorse, with its record in the Kentucky Derby standing at 2:01. Under normal circumstances, its sole anomalous property is the fact that it does not noticeably age.
SCP-2872’s other anomalous property manifests five years after the last time it won the Kentucky Derby. Whereas its usual demeanor is compliant, at this time it will become restless, and run in large loops. Within two days of entering this phase, SCP-2872 will start to run continuously, accelerating until it is fast enough to demolish any fence or wall in its way. It is physically unharmed by any impact in this state.
Once SCP-2872 is unimpeded, it will reach a top velocity of approximately 320m/s, and will continue to run in discorectangular tracks across distances measuring hundreds of kilometres. The only known way to cause SCP-2872 to decelerate is to make it hear the words “Whoa, boy!”; this will cause it to come to a stop over a period of 50m, though the sound must be adjusted to take into account the Doppler effect before it will have the desired effect.
SCP-2872 came to the Foundation’s attention in 196█, shortly after that year’s Kentucky Derby, in which it is believed to have placed second. This is the first recorded instance of SCP-2872 manifesting its anomalous acceleration, and was responsible for $30 million in damages, including the destruction of a three-mile tract of the I-24. After multiple attempts to restrain the as-yet unidentified anomaly, SCP-2872 was finally calmed by the intervention of a unknown African-American male in his late 50s, hypothesized to be the owner. He agreed to transfer custody of SCP-2872 to the Foundation, outlining the five-year principle for neutralization of the destructive effects, but left at significant speed before he could be questioned further. Attempts to trace him have been unsuccessful.
Attempts to house SCP-2872 with Foundation assets led to two further manifestations before an arrangement was made with a private stable and trainer, and SCP-2872 has consistently won his derbies since.
