Why is the UTMB race so famous?
The Ultra Trail du Mont Blanc ultra marathon is famous because it is a huge challenge, held in the trail running mecca of Chamonix along a well-known hiking route which circumnavigates a huge mountain.
As it is recognized as one of the toughest foot races in the World, each year we see it gaining in popularity, especially with runners traveling from overseas.
What is the elevation gain at UTMB?
During the 106 miles / 170km of running that participants will need to complete, UTMB runners also travel through high elevation passes (2,500m+ / 8,200ft+) and need to be able to manage themselves in changeable mountain conditions.
These conditions range from scorching summer heat to freezing high-altitude precipitation and even potentially snow.
Elevation gain during the Ultra Trail du Mont Blanc covers more than 10,000m (c.33,000ft) of climbing and the same descending.
How long does the UTMB race take to complete?
In addition to time barrier cut-offs during the UTMB race, runners have up to 46h30 to complete it.
Most people can expect to be out on the UTMB course over two nights, as the race starts at 6pm on the first night. The fastest finishers can complete the course in less than 21 hours!
It’s also worth noting that due to the level of difficulty, the drop-out rate (percentage of people not finishing) at the Ultra Trail du Mont Blanc can be up to around 40% of starters.
This rate is particularly high in years with bad weather (cold, wet and stormy) and really hot years, when runners can struggle with more challenging terrain and exposure during cold and wet / stormy weather, or with dehydration and gut issues when attempting the race in hot summer conditions.
Can I have a pacer at UTMB?
