So, what is the UTMB and how do the World Finals work?

For most avid trail runners the UTMB is the pinnacle of their year where they can test their skills, and put into practice everything they have worked hard for. Think of it like the World Cup is to football.

Every August, a small alpine town in the shadow of Mont Blanc becomes the epicenter of the trail running world. Chamonix, France, hosts the Ultra-Trail du Mont-Blanc (UTMB), a race that has grown from a humble idea into the crown jewel of the trail running calendar. What started in 2003 with just a few hundred participants has evolved into a global phenomenon, known today as the UTMB World Finals—a week-long celebration of endurance, grit, and the indomitable human spirit.

The Origins of UTMB

The UTMB was born from a simple yet ambitious vision: to create a race that circumnavigates the towering Mont Blanc, Europe's highest peak. The inaugural event saw a small but passionate group of runners attempt the 171-kilometer journey through France, Italy, and Switzerland. With an elevation gain of over 10,000 meters, the course was, and still is, a formidable challenge. But the race’s breathtaking scenery, rugged trails, and the camaraderie among competitors quickly earned it a reputation as one of the toughest and most prestigious trail races in the world.

What are the UTMB World Finals?

Today, the UTMB World Finals are more than just a single race—they are the culmination of a year-long series of events that span the globe. Runners from all over the world participate in qualifying races, each earning points and coveted UTMB Indexes that allow them to enter the lottery for a spot in one of the final races in Chamonix. The Finals consist of several races, each varying in distance and difficulty, but all sharing the same sense of awe-inspiring adventure.

The Races

The UTMB World Finals include a range of races designed to test every aspect of a trail runner's abilities:

- UTMB (171 km): The queen race, circling Mont Blanc and traversing three countries—France, Italy, and Switzerland. With 10,000 meters of elevation gain, this race is a true test of endurance and mental fortitude.

- CCC (100 km): The Courmayeur-Champex-Chamonix race, often seen as the gateway to the full UTMB, takes runners through some of the most scenic sections of the Mont Blanc massif.

- TDS (145 km): The Sur les Traces des Ducs de Savoie is a technical and challenging race that offers more rugged terrain and a higher degree of difficulty.

- OCC (55 km): A shorter, but no less intense race that allows newer ultra runners to experience the magic of UTMB.

- PTL (300 km): La Petite Trotte à Léon is a team race with no marked course, offering a true adventure over multiple days.

The Road to UTMB

1. Complete a UTMB World Series event or major

You can earn Running Stones by finishing races at any of the 43 UTMB World Series events around the world, including in Europe, North America, Asia, Oceania, and Africa. You can also earn double the amount of stones by finishing their major events. The more stones you have, the better your chances of getting into the lottery. 

2. Get a valid UTMB Index

You need a valid UTMB Index in the category you want to compete in. For example, to enter the 100M race lottery, you need to have completed a 100M event. You can earn a valid index by completing races in the relevant category, such as the Western States Endurance Run for the 100M race. You can also validate your index at over 5,000+ races around the world. 

3. Enter the lottery

The lottery opens in mid-December and closes about a month later. You can pre-register from around December 14, 2024 at 11 AM (Paris time) until January 11, 2025 at 11:59 PM (Paris time). Only runners who are admitted to the draw on January 11, 2025 will be able to participate. UTMB will notify you if you are selected. 

In addition to qualifying through the lottery, the top three men and women in each of the 50K, 100K, and 100M categories automatically qualify for the Finals. Elite athletes may also receive direct access to the Finals based on their performance.

The Queen Race: UTMB

The UTMB race itself is a monumental 171-kilometer journey that begins and ends in Chamonix, taking runners on a breathtaking tour of the Mont Blanc massif. The course covers a variety of terrains—from technical single tracks to rolling hills—through three countries. Runners face not only the grueling physical challenge of 10,000 meters of ascent and descent but also unpredictable weather conditions, which can range from scorching heat to freezing snow.

This combination of length, elevation, and environment is what makes UTMB one of the hardest trail races in the world. It’s a race where the physical challenge is only part of the story; the mental battle is just as fierce. Finishing UTMB is a badge of honor, a testament to a runner’s determination, preparation, and willpower.

The Pinnacle of Trail Running

For elite trail runners, the UTMB is a bucket-list race, one that represents the pinnacle of their sport. Winning UTMB can cement a runner’s legacy, while simply finishing is a lifelong achievement. The race draws thousands of spectators and some of the best athletes in the world, all converging in Chamonix for a week of shared passion and incredible performances.

In many ways, the UTMB World Finals are not just a race, but a pilgrimage for those who love the mountains, the trails, and the spirit of adventure. Whether you're an elite athlete or an everyday trail enthusiast, the allure of the UTMB is irresistible—a chance to push beyond your limits in one of the most stunning natural arenas the world has to offer.
