Marathons are divided into three types: full marathon, half marathon, and quarter marathon. What we usually refer to as a marathon is a full marathon, while the other two forms are set up to meet the needs of different groups of people.
Marathon races are held throughout the year, and urban roads are generally used for the race track. In areas with poor conditions, even dirt roads are used. However, the marathon distance and smoothness vary in each region.
Generally speaking, untrained ordinary people need to run a marathon for at least 6 hours, or even longer. However, if they have received basic training for about a year, they can roughly run within 5 hours. If the training time exceeds 5 years, they should be able to run within 4 hours.
