The Ultra Trail du Mont Blanc (UTMB) is one of the world’s best known endurance running events, taking place each August. It is the centrepiece of a week-long event, based in Chamonix, France, which sees almost 10,000 runners compete in seven different races. A brutal 170km route, it features more than 10km of ascent.
Here is our full guide to learning about the event, following it live or even taking part.
Date, start time & live tracking
UTMB 2022 starts at 1600 UK on Friday August 26, 2022, with runners having 46 hours 30 minutes to complete the course.

Ultra Trail du Mont Blanc (UTMB) Route
The UTMB is a 170km loop that takes runners through three countries; France, Switzerland and Italy. On many occasions the course goes above 2,500m in altitude as competitors follow the Tour Du Mont Blanc route. The race begins in Chamonix and heads anticlockwise to Saint Gervais, Les Contamines and La Balme. Les Chapieux and Lac Combal are checkpoints five and six before the race goes over Mont Blanc itself (4,810m). The route continues via Arnouvaz, La Fouly and Triente, with runners required to make it back to Chamonix inside the 46:30 cut-off point.
Facts, Tips & FAQ
The UTMB was first held in 2003 when only 67 runners completed the course. Tackling rain, hail and cold weather, Nepal’s Dawa Sherpa and USA’s Krissy Moehl were the inaugural men’s and women’s winners.
Two years later, Britain’s Lizzy Hawker won her first UTMB title. She has since recorded another four victories and holds the record for podium placings with six, having also finished second in 2009.
While Hawker is the UTMB’s leading lady, Frenchman Francois D’Haene tops the men’s rankings with four wins. These have all come in his last four starts: 2012, 2014, 2017 and 2021.
The age range of elite competitors at mountain running’s most famous event is illustrated by the men’s winners from 2006 to 2008. Italian veteran Marco Olmo finished strongly to take victory aged 58 and 59 in 2006 and 2007, clocking 21:06:06 and 21:31:58 respectively.
The following year saw the now legendary Spaniard Kilian Jornet claim the spoils aged just 20 and the youngest entrant in the race. Jornet has since completed a hat-trick of titles.
As well as tackling the challenging terrain, runners must be prepared for a considerable range of weather conditions.
The average maximum temperature for Chamonix in late August is 26°C, with the daytime average around 21°C. Overnight, temperatures average 10°C, with 6°C not uncommon.
With every 1000m of ascent, you can expect a 6.5°C drop in temperature, which is why runners are required to carry such a variety of clothing.
On average, the last week of August only features one day of rain, but light showers are fairly likely.
How to qualify and enter for Ultra Trail du Mont Blanc (UTMB)
Qualification for the UTMB is based around a points system called Running Stones. The more qualifying races runners compete in and the more highly rated the event is, the greater chance they have of earning a place through the ballot. All the details can be found here.
Ultra Trail du Mont Blanc (UTMB) records and past winners
France’s Francois D’Haene is the most successful male runner in UTMB history with his four wins coming in 2012, 2014, 2017 and 2021. Spain’s Kilian Jornet could match that feat with victory this summer. Great Britain’s Lizzy Hawker is the most successful female runner, having also won four times – in 2005, 2008, 2010 and 2011.
Different reports credit D’Haene and Spain’s Pau Capell with the men’s course record. D’Haene clocked 20:11:44 in 2014 and Capell 20:19:07 in 2019, but distances have been adapted over the years due to weather conditions. In 2020, with the race postponed due to Covid-19, Capell attempted to break the 20-hour barrier in a solo effort, but his “Breaking 20” bid came up short.
There is, however, universal agreement that USA’s Courtney Dauwalter set a new women’s record in 2021. Dawaulter finished seventh overall as she clocked 22:30:55 that year. This was six minutes 42 seconds faster than the previous record set by fellow American Rory Bosio in 2013. Dauwalter’s effort was even more impressive, since the course was around 3km longer in 2021 than in 2013.
