Alaska is known for its cold snowy weather. For many years, dog sleds were the only means of transportation. Many Alaskans combine fun and hard work in an annual dog sled race. The trail race is the longest dog sled race in the world. It lasts from two to three weeks and covers almost 17 hundred km. The race goes across Alaska from Anchorage to Rome. It follows the trails that were once used by the people who looked for gold in Alaska’s wilderness. The race also follows the route of several brave Alaskans who brought medicine from Anchorage to Rome in the winter of 1925. They carded the badly needed medicine through bad storm and helped save many lives. The race from Anchorage to Rome which is held in March is very hard for the drivers and sleigh dogs. Each day the dogs run for about four hours and then rest for four hours. They run day and night, and sometimes travel as much as one hundred and ten km. a day. The drivers must feed and take care of the dogs at race periods. Sometimes they only sleep for about two hours each day. Because the race is so hard, many drivers do not expect to win. For most of them just being able to finish is a victory.
