American River Endurance Run
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 trails used by the riders and horses of this event, 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.
