Read the passage. The first car race was held in November 1895 in Chicago. The race was put on by a man who owned the Chicago Times-Herald newspaper. The course was just a little over 50 miles long.

During the race, conditions were difficult. The roads were bumpy and full of holes. And, it had snowed. So, the roads were slippery and had big snowdrifts. Since the cars were not heated, the drivers also had to withstand the cold.

Still, six drivers competed. J. Frank Duryea raced the car he and his brother invented. He drove for nine hours in the freezing cold to win the race.
