Multiday race

Running event across multiple days Multiday races are ultramarathon running events which are typically either segmented into daily events of a specified distance or time, or staged so that runners can run as far as they want, at their own discretion, over a set course or over a set number of days. Multiday races can range from continuous 48-hour track events to staged transcontinental treks. Beyond the marathon Very long endurance running events can be divided into three broad categories: the traditional 26.2-mile (42.2 km) marathon, the ultramarathon—defined as any event longer than the marathon—and true multiday events, which begin with the 24-hour event and can stretch out almost indefinitely, often ranging from six days to 3,100 miles (5,000 km) or longer. Multiday events are usually timed races, such as 48-hour, 72-hour, and 6-day races. Set-distance races depend on the ability of the runner to complete them, and what may be a multiday event for slower runners may be an ultra for faster athletes. For example, the Badwater Ultramarathon, a 135 miles (217 km) race, has a 48-hour time limit, but winners typically finish in under 24 hours. Types of courses Many multiday races
