An ultramarathon is a long-distance running event that exceeds the traditional marathon distance of 26.2 miles (42.2 kilometers). These races can vary in length, often starting at 50 kilometers and going up to 100 miles or more. Ultramarathons can take place on roads, trails, or even in extreme environments, challenging runners both physically and mentally. Participants in ultramarathons must prepare extensively, as the races can last several hours or even days. Runners often develop strategies for hydration, nutrition, and pacing to help them endure the grueling distances. Many ultramarathon events also foster a strong sense of community among participants, creating lasting friendships and support networks.
