It all started with a conversation between Sally Edwards and Mo Livermore back in 1979. At that time, The American River Ride (horse race) started in Sacramento and finished in Auburn. When Mo described the venue and trails, Sally realized the course could be a challenging and beautiful 50-mile endurance run. And thus, a race was born. In 1980, nearly 200 runners toed the line at the Auburn Fair Grounds for the start of the inaugural AR50. Since 1982, the run has started in Sacramento. Over the years, a total of more than 10,800 runners have crossed the finish line.
