Ultramarathons—races longer than the standard 26.2-mile marathon distance—have grown in popularity over the last couple of decades. From 50K races to 100-mile events, and beyond, the ultramarathon community continues to expand.

Ultra runners are a unique breed. They’re willing to push their bodies to extreme limits and spend entire days or nights on their feet running. The mental toughness required for an ultramarathon is perhaps even greater than for a standard marathon.

Many ultrarunners start as marathon runners before gradually extending their distances. The skills and mindset developed through marathon training translate well to ultras.

The ultramarathon community tends to be very welcoming and supportive. Aid stations are staffed by volunteers who often have running experience themselves, and fellow runners are typically very encouraging and helpful, especially in the later stages of long races when the going gets tough.

If you’re curious about ultras, consider starting with a 50K race—a good stepping stone from the marathon distance. The experience will teach you a lot about yourself and what you’re capable of achieving.
