Surprise K is a four-race series staged across the Central Savannah River Area beginning February 20, 2027. Every event shares one defining rule: the distance is never disclosed before the start. Runners line up knowing only that the course falls somewhere between one and ten miles. There is no published route, no announced mileage, and no opportunity to pace against a known finish line. Course markers are the primary navigation method. Runners follow the physical markings and adapt in real time as the distance unfolds beneath them.
