City2Surf is a popular road running event held annually in Sydney covering a 14-kilometre (8.7 mi) course. The event is a "fun run" as well as a race, attracting both competitive runners and community participants who can choose to run or to walk. The event attracts more than 80,000 entrants who start in staggered groups based on previous running times and early entry.

Road running is the sport of running on a measured course over an established road. This differs from track and field on a regular track and cross country running over natural terrain.
