ANCHORAGE, Alaska (AP) - More than 20 mushers in the 2018 Iditarod Trail Sled Dog Race have reached the checkpoint at Rainy Pass.

Sixty-seven teams departed Sunday on the 1,000-mile (1,600-kilometer) race from Willow, Alaska, to the Nome on the state's west coast.

The trail winds over frozen lakes and rivers, through mountain passes and over trails once used to deliver mail and supplies to mining communities.

The Rainy Pass checkpoint is 142 miles (228 kilometers) from the starting line.

From the checkpoint, mushers climb from over 1,800 feet (550 meters) to the highest point of the pass at an elevation of 3,160 feet (965 meter) over mostly barren terrain.

Two Alaska mushers, Jessie Holmes of Nenana (nee-NA-nah) and Richie Diehl (deel) of Aniak AN-ee-ak) had left the Rainy Pass checkpoint by mid-afternoon Monday.
