Ultra-Trail Du Mont-Blanc

The Ultra-Trail du Mont-Blanc (also referred to as UTMB) is a single stage mountain ultramarathon. It takes place once a year in the Alps, across France, Italy and Switzerland. The distance is approximately 166 km, with a total elevation gain of around 9,400 m. It is widely regarded as the most difficult foot race in Europe.

While the best runners complete the loop in slightly more than 20 hours, most runners take 30 to 45 hours to reach the finish line. There is no prize money awarded.

From 2006, a second race Courmayeur - Champex - Chamonix (half-loop) has also been organised, and a third race was added in 2009: "Sur les Traces des Ducs de Savoie".

Today, the races consist of the following;

  • UTMB: Ultra-Trail du Tour du Mont-Blanc (166 km +9,400 m)
  • CCC: Courmayeur - Champex - Chamonix (98 km +5,600 m)
  • TDS: Sur les Traces des Ducs de Savoie (105 km +6,700 m)
  • PTL: La Petite Trotte à Léon (250 km +18,000 m)
