UTMB Mont Blanc 2023: Everything you don't know about the world's most important ultra-trail event

The Ultra Trail du Mont Blanc (UTMB) has evolved over the years to become the most prestigious ultratrail race in the world. Its challenging course, majestic surroundings and the participation of elite runners have cemented its status in the world of trail running. In 2023, despite the absence of Kilian Jornet due to injury, the race promises to be as exciting as ever. But what makes the UTMB so special?

History and origin

The Ultra-Trail de Mont-Blanc, commonly known as UTMB, is more than a mountain ultra-marathon; it is an event that has defined and redefined the ultratrail world since its inception. Founded in 2003, this race has evolved from a challenge for a brave few to become the most prestigious trail running competition in the world.

The UTMB takes place annually in the majestic scenery of the Alps, spanning three countries on its course: France, Italy and Switzerland. With a challenging distance of 171 km and a positive elevation gain of 10,000 meters, it is no wonder that it is considered the most prestigious trail running foot race in the world. Over the years, it has attracted around 2,500 participants in each edition, making it one of the most numerous races of its kind.

While elite runners complete this course in just over 20 hours, most participants cross the finish line between 30 and 46 hours, reflecting the toughness and demanding nature of the event.

Since 2006, the event has expanded to include other races, adapting to different levels of ability and endurance. In 2006, a second race was introduced with half the course, known as Courmayeur, Champex, Chamonix (CCC). In 2009, a third race called "Sur les Traces des Ducs de Savoie" (TDS) was added. As of today, the races that are part of the event are:

• UTMB: Ultra-Trail du Tour du Mont-Blanc (171 km +10,040 m).
• CCC: Courmayeur - Champex - Chamonix (101 km +6,100 m)
• TDS: In the footsteps of the Dukes of Savoy (145 km 9,100 m)
• PTL: La Petite Trotte à Léon (300 km +25,000 m)
• MCC: A 40 km race with an elevation gain of 2400 m, which was introduced in 2018. This race has the particularity of consolidating teams and is oriented as a festive competition.

The UTMB has not only grown in terms of participants and variety of races, but has also left an indelible mark on the history of ultratrail, creating unforgettable moments and forging champions who have left their mark on the trails of Montblanc.

A course that challenges and dazzles

The Ultra-Trail du Mont-Blanc is not just a race; it is an odyssey that takes runners through some of the most breathtaking mountain scenery in the world. Here is a more detailed description of this iconic course:

3. Unpredictable weather conditions:
Given its altitude and location, the weather on Mont Blanc can change quickly. Runners can experience scorching sun, torrential rain, freezing wind and snow, all in the course of the same race. This weather variability adds an element of uncertainty and requires participants to be well prepared with appropriate equipment.

4. Challenging ascents and descents:
