Around 100 miles (160 km) is typically the longest course distance raced in under 24 hours, but there are also longer multiday races commonly held as 48 hours, 200 miles (320 km), or more, sometimes raced in stages with breaks for sleep.

The oldest and largest ultramarathons are on road, including the Comrades Marathon (over 10,000 finishers annually) and Two Oceans Marathon (over 6,000 finishers annually). The world's longest certified Footrace is the Self-Transcendence 3100 Mile Race. Many ultras have historical significance, including the Spartathlon, based on the 246 km run of Greek messenger Pheidippides from Athens to Sparta during the Battle of Marathon in a day and a half to seek aid against the Persians.
