Ultimate List of Ultra Races

Ultra races, also known as extreme or endurance races, push athletes to their physical and mental limits. These events test not just speed and strength, but also resilience, strategy, and recovery. If you're a seasoned runner or an adventurous beginner, these challenges are worth exploring.

Ultra races cater to a wide range of interests and abilities, encompassing various disciplines and distances. From marathons that extend beyond the traditional 42.195km to multi-day events covering hundreds of kilometers, there's an ultra race out there for everyone. Let's delve into the world of ultra races, exploring some of the most prestigious, challenging, and unique events.

Distance-Based Ultra Races

One way to categorize ultra races is by distance. After the marathon, distances can range from 50km to over 200km in a single stage. Here, we highlight two iconic distance-based ultra races:

50km and 50-mile Races

The 50km and 50-mile races are popular entry points for newcomers to the ultra world. These distances provide a significant challenge without the multi-day commitment of longer races. Examples include the JFK 50 Mile in the U.S. and the 53km Lavaredo Ultramarathon in Italy.

While these races still demand immense training and preparation, they offer a more accessible introduction to ultra running. However, don't underestimate the challenge - a 'mere' 50km or 80km can still reap havoc on the unprepared body and mind.

100km and 100-mile Races

Stepping up from the 50km and 50-mile races, 100km and 100-mile events are iconic ultra distances. The 100km distance, predicted by Bill Bowerman to be the perfect ultra distance (the 'magic number'), is challenged each year at races like the Spartathlon in Greece.

The 100-mile distance is particularly revered in the U.S., with historic races like the Western States Endurance Run and the Leadville Trail 100. These races test not just speed, but also strategy, nutrition, and mental fortitude. The achievement of completing a 160km or 160-mile race is a testament to true ultrarunning grit.

Multi-Day Ultra Races

While single-stage ultra races are impressive, multi-day events take endurance to another level. These races demand not just daily physical prowess, but also recovery, strategy, and mental stamina to keep going over multiple days. Two standout multi-day ultra races are:

The Barkley Marathons

Arguably the world's toughest foot race, the Barkley Marathons is a mythical, multi-day ultra race hidden in the Tennessee hills. With a non-existent course, brutal climbs, and a 60-hour time limit, the Barkley's legend grew through its high failure rate and elusive entry process. Only 15 people have ever finished it.

The Barkley's infamy is further enhanced by its mysterious race director, Laz Lake, and its idiosyncratic entry procedure - entrants must apply by post, with Laz hand-picking the field. Completing this race enters runners into the ranks of ultra running's eclectic elite.

The Marathon des Sables

In the Sahara Desert, the Marathon des Sables (MdS) is a self-sufficient multi-stage race covering approximately 250km over six days. Participants carry their food, clothing, and gear, plus sleeping supplies and a minimum food allowance. Water is rationed at checkpoints.

The MdS isn't just about running in extreme heat - it's about survival, navigation, and resource management. It's a slog through desert terrain, where mantenir en mouvement (keep moving) is the mantra. This race pushes runners to the brink, testing not just fitness, but also willpower and mental resolve.

Ultra races, in their various forms, epitomize human endurance and spirit. Whether you're aiming for a specific distance or multi-day experience, there's an ultra race out there for you. Training, preparation, and mindset are crucial, but one thing's for certain - crossing the finish line of an ultra race will leave you forever changed.
