Close to the end of October keen marathoners of various ages and abilities are invited to the annual Amman Marathon. The route runs across Amman's downtown which is free from traffic only once per year specifically for this occasion. Runners have an excellent opportunity to observe beautiful Roman ruins in the morning sun. Adults may choose between a regular 42 km race, though easier 21 km and 10 km are also available. A separate race is organized for children and takes place a week before the major marathon.
